+        for the kernel:         
+            config-accton-as5712_54x.patch 
+                    for kernel configuration.
+            driver-i2c-muxes-pca954x-always-deselect.patch 
+                    for i2c_mux deselects after transaction.
+            driver-patches-for-accton-as5712-fan-psu-cpld.patch
+                    for as5712's fan/psu/cpld/led/sfp drivers.
+        for ONIE:
+            onie_installer-accton-AS5712-54X.patch 
+                    for console port setting and copy util script o rootfs.
+  module - Contains source code of as5712 kernel driver modules.
+
+The late Sonic building scripts, pushed @Dec 5 2016, will automatically 
+create a docker container and run building process under it.
+User is not necessary to handle docker environment creation.
+
+1. Download sonic-buildimage environment.
+  - Run "git clone https://github.com/Azure/sonic-buildimage".
+  - cd to sonic-buildimage and run "git submodule update --init --recursive".
+2. Build kernel
+  - cd ./src/sonic-linux-kernel
+  - Copy patches and series from patch/kernel of this release to 
+    sonic-linux-kernel/patch.
+  - Build kernel by "make".
+  - The built kernel package, linux-image-3.16.0-6-amd64_3.16.51-3+deb8u1_amd64.deb
+    , is generated.
+3. Build installer 
+  - Change directory back to sonic-buildimage/.
+  - Get onie_installer-accton-AS5712-54X.patch" from patch/installer.
+  - Change setting for AS5712-54X by patching build_image.sh.
+    "patch -p1 < onie_installer-accton-AS5712-54X.patch"
+    !!NOTICE, patching onie_installer-accton-AS5712-54X.patch comments out the
+    "git status" checking at build_image.sh.
+  - The account and password of installed OS can be given at rules/config.
+    The default user and password are "admin" & "YourPaSsWoRd" respectively.
+  - Run "make configure PLATFORM=broadcom"
+  - Copy the built kernel debian package to target/debs/.
+    The file is linux-image-3.16.0-6-amd64_*_amd64.deb under directory
+    src/sonic-linux-kernel/.
+  - Run "make target/sonic-generic.bin"
+  - Get the installer, target/sonic-generic.bin, to target machine and install.
+
+All Linux kernel code is licensed under the GPLv1. All other code is
+licensed under the GPLv3. Please see the LICENSE file for copies of
+both licenses.
+
+The code for integacting with Accton AS5712-54X has 2 parts, 
+kernel drivers and operational script. 
+The kernel drivers of peripherals are under module/ directory.
+1.  These drivers are patched into kernel by 
+    driver-patches-for-accton-as5712-fan-psu-cpld.patch
+    Or you can build the driver under module/ by setting environment variable, 
+    KERNEL_SRC, to proper linux built directory and run make. 
+    It may be sonic-linux-kernel/linux-3.*/debian/build/build_amd64_none_amd64/.
+2.  A operational script, accton_as5712_util.py, for device initializatian and 
+    peripheral accessing should be installed at /usr/bin. 
+    This script is generated by onie_installer-accton-AS5712-54X.patch.
+    It's done by patching onie_installer-accton-AS5712-54X.patch at build-image.
+    Run "accton_as5712_util.py install" to install drivers.
+
+To initialize the system, run "accton_as5712_util.py install".
+To clean up the drivers & devices, run "accton_as5712_util.py clean".
+To dump information of sensors, run "accton_as5712_util.py show".
+To dump SFP EEPROM, run "accton_as5712_util.py sff".
+To set fan speed, run "accton_as5712_util.py set fan".
+To enable/disable SFP emission, run "accton_as5712_util.py set sfp".
+To set system LEDs' color, run "accton_as5712_util.py set led"
+For more information, run "accton_as5712_util.py --help".
+
+====================================================================
+Besides applying accton_as5712_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+System LED:
+    There are 5 system LEDs at the lower-left corner of front panel.
+    They are  loc, diag, fan, ps1, and ps2. 
+    The sysfs interface color mappings are as follows:
+    Brightness:
+        0 => off
+        1 => green
+        2 => amber
+        3 => red
+        4 => blue
+    But not all colors are available for each LED.
+
+Fan Control:
+    There are 10 fans inside 5 fan modules.
+    All fans share 1 duty setting, ranged from 0~100.
+
+Thermal sensers:
+    3 temperature sensors are controlled by the lm75 kernel modules. 
+
+PSUs:
+    There 2 power supplies slot at the left/right side of the back.
+    Once if a PSU is not plugged, the status of it is shown failed.
+
+There are 48 SFP+ and 6 QSFP modules are equipped. 
+Before operating on PSU and QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+To set system LEDs' color, run "accton_as5812_54t_util.py set led"
+For more information, run "accton_as5812_54t_util.py --help".
+
+====================================================================
+Besides applying accton_as5812_54t_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+LED controls can be found under /sys/class/leds. The sysfs interface
+color mappings are as follows:
+Brightness:
+  0 => off
+  1 => green
+  2 => amber
+  3 => red
+  4 => blue
+
+There are 5 system LEDs, loc, diag, fan, ps1, and ps2. 
+They are lit automatically by CPLD, but the loc and diag.
+The loc led has only 1 color, blue.
+The diag one has 3 colors: red, amber, and green.
+
+Fan controls can be found in /sys/bus/i2c/devices/2-0066.
+There are 12 fans inside 6 fan modules.
+All fans share 1 duty setting, ranged from 0~100.
+
+Three temperature sensors are controlled by the lm75 kernel modules. 
+They should already be visible under /sys/bus/i2c/drivers/lm75/.
+
+Two power supplies are controlled by the CPLD. 
+Here provide their status under
+/sys/bus/i2c/devices/10-0050 and /sys/bus/i2c/devices/11-0053.
+
+There are 32 QSFP+ modules are equipped. 
+Apply "accton_as5812_54t_util.py show" to get their status. 
+Apply "accton_as5812_54t_util.py set sfp" to turn on/off light transmission.
+Apply "accton_as5812_54t_util.py sff" to dump EEPROM information.
+Before operating on that QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+                    for as7312's fan/psu/cpld/led/sfp drivers.
+        for ONIE:
+            onie_installer-accton-AS7312-54X.patch 
+                    for console port setting and copy util script o rootfs.
+  module - Contains source code of as7312 kernel driver modules.
+
+The late Sonic building scripts, pushed @Dec 5 2016, will automatically 
+create a docker container and run building process under it.
+User is not necessary to handle docker environment creation.
+
+1. Download sonic-buildimage environment.
+  - Run "git clone https://github.com/Azure/sonic-buildimage".
+  - cd to sonic-buildimage and run "git submodule update --init --recursive".
+2. Build kernel
+  - cd ./src/sonic-linux-kernel
+  - Copy patches and series from patch/kernel of this release to 
+    sonic-linux-kernel/patch.
+  - Build kernel by "make".
+  - The built kernel package, linux-image-3.16.0-6-amd64_3.16.51-3+deb8u1_amd64.deb
+    , is generated.
+3. Build installer 
+  - Change directory back to sonic-buildimage/.
+  - Get onie_installer-accton-AS7312-54X.patch" from patch/installer.
+  - Change setting for AS7312-54X by patching build_image.sh.
+    "patch -p1 < onie_installer-accton-AS7312-54X.patch"
+    !!NOTICE, patching onie_installer-accton-AS7312-54X.patch comments out the
+    "git status" checking at build_image.sh.
+  - The account and password of installed OS can be given at rules/config.
+    The default user and password are "admin" & "YourPaSsWoRd" respectively.
+  - Run "make configure PLATFORM=broadcom"
+  - Copy the built kernel debian package to target/debs/.
+    The file is linux-image-3.16.0-6-amd64_*_amd64.deb under directory
+    src/sonic-linux-kernel/.
+  - Run "make target/sonic-generic.bin"
+  - Get the installer, target/sonic-generic.bin, to target machine and install.
+
+All Linux kernel code is licensed under the GPLv1. All other code is
+licensed under the GPLv3. Please see the LICENSE file for copies of
+both licenses.
+
+The code for integacting with Accton AS7312-54X has 2 parts, 
+kernel drivers and operational script. 
+The kernel drivers of peripherals are under module/ directory.
+1.  These drivers are patched into kernel by 
+    driver-patches-for-accton-as7312-fan-psu-cpld.patch
+    Or you can build the driver under module/ by setting environment variable, 
+    KERNEL_SRC, to proper linux built directory and run make. 
+    It may be sonic-linux-kernel/linux-3.*/debian/build/build_amd64_none_amd64/.
+2.  A operational script, accton_as7312_util.py, for device initializatian and 
+    peripheral accessing should be installed at /usr/bin. 
+    This script is generated by onie_installer-accton-AS7312-54X.patch.
+    It's done by patching onie_installer-accton-AS7312-54X.patch at build-image.
+    Run "accton_as7312_util.py install" to install drivers.
+
+To initialize the system, run "accton_as7312_util.py install".
+To clean up the drivers & devices, run "accton_as7312_util.py clean".
+To dump information of sensors, run "accton_as7312_util.py show".
+To dump SFP EEPROM, run "accton_as7312_util.py sff".
+To set fan speed, run "accton_as7312_util.py set fan".
+To enable/disable SFP emission, run "accton_as7312_util.py set sfp".
+To set system LEDs' color, run "accton_as7312_util.py set led"
+For more information, run "accton_as7312_util.py --help".
+
+====================================================================
+Besides applying accton_as7312_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+System LED:
+    There are 5 system LEDs at the lower-left corner of front panel.
+    They are  loc, diag, fan, ps1, and ps2. 
+    The sysfs interface color mappings are as follows:
+    Brightness:
+        0 => off
+        1 => green
+        2 => amber
+        3 => red
+        4 => blue
+    But not all colors are available for each LED.
+
+Fan Control:
+    There are 10 fans inside 5 fan modules.
+    All fans share 1 duty setting, ranged from 0~100.
+
+Thermal sensers:
+    3 temperature sensors are controlled by the lm75 kernel modules. 
+
+PSUs:
+    There 2 power supplies slot at the left/right side of the back.
+    Once if a PSU is not plugged, the status of it is shown failed.
+
+There are 48 SFP+ and 6 QSFP modules are equipped. 
+Before operating on PSU and QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+Contents of this package:
+  module - Contains source code of as7326 kernel driver modules.
+  util   - operational scripts.
+
+Sonic creates a docker container and run building process under it.
+If user tries to built new drivers, please get into that docker and 
+dpkg-buildpackage for them.
+
+All Linux kernel code is licensed under the GPLv1. All other code is
+licensed under the GPLv3. Please see the LICENSE file for copies of
+both licenses.
+
+The code for integacting with Accton AS7326-56X has 2 parts, 
+kernel drivers and operational script. 
+The kernel drivers of peripherals are under module/ directory.
+1.  These drivers can be built to individual ko during dpkg-buildpackage.
+2.  A operational script, accton_as7326_util.py, for device initializatian.
+    Run "accton_as7326_util.py install" to install drivers.
+
+To initialize the system, run "accton_as7326_util.py install".
+To clean up the drivers & devices, run "accton_as7326_util.py clean".
+To dump information of sensors, run "accton_as7326_util.py show".
+To dump SFP EEPROM, run "accton_as7326_util.py sff".
+To set fan speed, run "accton_as7326_util.py set fan".
+To enable/disable SFP emission, run "accton_as7326_util.py set sfp".
+To set system LEDs' color, run "accton_as7326_util.py set led"
+For more information, run "accton_as7326_util.py --help".
+
+====================================================================
+Besides applying accton_as7326_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+System LED:
+    There are 5 system LEDs at the lower-left corner of front panel.
+    They are  loc, diag, fan, ps1, and ps2. 
+    The sysfs interface color mappings are as follows:
+    Brightness:
+        0 => off
+        1 => green
+        2 => amber
+        3 => red
+        4 => blue
+    But not all colors are available for each LED.
+
+Fan Control:
+    There are 10 fans inside 6 fan modules.
+    All fans share 1 duty setting, ranged from 0~100.
+
+Thermal sensers:
+    3 temperature sensors are controlled by the lm75 kernel modules. 
+
+PSUs:
+    There 2 power supplies slot at the left/right side of the back.
+    Once if a PSU is not plugged, the status of it is shown failed.
+
+There are 48 SFP+ and 8 QSFP modules are equipped. 
+Before operating on PSU and QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+
+To initialize the system, run "accton_as7712_util.py install".
+To clean up the drivers & devices, run "accton_as7712_util.py clean".
+To dump information of sensors, run "accton_as7712_util.py show".
+To dump SFP EEPROM, run "accton_as7712_util.py sff".
+To set fan speed, run "accton_as7712_util.py set fan".
+To enable/disable SFP emission, run "accton_as7712_util.py set sfp".
+To set system LEDs' color, run "accton_as7712_util.py set led"
+For more information, run "accton_as7712_util.py --help".
+
+====================================================================
+Besides applying accton_as7712_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+LED controls can be found under /sys/class/leds. The sysfs interface
+color mappings are as follows:
+Brightness:
+  0 => off
+  1 => green
+  2 => amber
+  3 => red
+  4 => blue
+
+There are 5 system LEDs, loc, diag, fan, ps1, and ps2. 
+They are lit automatically by CPLD, but the loc and diag.
+The loc led has only 1 color, blue.
+The diag one has 3 colors: red, amber, and green.
+
+Fan controls can be found in /sys/bus/i2c/devices/2-0066.
+There are 12 fans inside 6 fan modules.
+All fans share 1 duty setting, ranged from 0~100.
+
+Three temperature sensors are controlled by the lm75 kernel modules. 
+They should already be visible under /sys/bus/i2c/drivers/lm75/.
+
+Two power supplies are controlled by the CPLD. 
+Here provide their status under
+/sys/bus/i2c/devices/10-0050 and /sys/bus/i2c/devices/11-0053.
+
+There are 32 QSFP+ modules are equipped. 
+Apply "accton_as7712_util.py show" to get their status. 
+Apply "accton_as7712_util.py set sfp" to turn on/off light transmission.
+Apply "accton_as7712_util.py sff" to dump EEPROM information.
+Before operating on that QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+/*
+ *	Description:
+ *	a) Optical transceiver EEPROM read/write transactions are just like
+ *		the at24 eeproms managed by the at24.c i2c driver
+ *	b) The register/memory layout is up to 256 128 byte pages defined by
+ *		a "pages valid" register and switched via a "page select"
+ *		register as explained in below diagram.
+ *	c) 256 bytes are mapped at a time. 'Lower page 00h' is the first 128
+ *	        bytes of address space, and always references the same
+ *	        location, independent of the page select register.
+ *	        All mapped pages are mapped into the upper 128 bytes 
+ *	        (offset 128-255) of the i2c address.
+ *	d) Devices with one I2C address (eg QSFP) use I2C address 0x50 
+ *		(A0h in the spec), and map all pages in the upper 128 bytes
+ *		of that address.
+ *	e) Devices with two I2C addresses (eg SFP) have 256 bytes of data
+ *		at I2C address 0x50, and 256 bytes of data at I2C address
+ *		0x51 (A2h in the spec).  Page selection and paged access
+ *		only apply to this second I2C address (0x51).
+ *	e) The address space is presented, by the driver, as a linear 
+ *	        address space.  For devices with one I2C client at address
+ *	        0x50 (eg QSFP), offset 0-127 are in the lower
+ *	        half of address 50/A0h/client[0].  Offset 128-255 are in
+ *	        page 0, 256-383 are page 1, etc.  More generally, offset
+ *	        'n' resides in page (n/128)-1.  ('page -1' is the lower
+ *	        half, offset 0-127).

+        for the kernel:         
+            config-accton-as5712_54x.patch 
+                    for kernel configuration.
+            driver-i2c-muxes-pca954x-always-deselect.patch 
+                    for i2c_mux deselects after transaction.
+            driver-patches-for-accton-as5712-fan-psu-cpld.patch
+                    for as5712's fan/psu/cpld/led/sfp drivers.
+        for ONIE:
+            onie_installer-accton-AS5712-54X.patch 
+                    for console port setting and copy util script o rootfs.
+  module - Contains source code of as5712 kernel driver modules.
+
+The late Sonic building scripts, pushed @Dec 5 2016, will automatically 
+create a docker container and run building process under it.
+User is not necessary to handle docker environment creation.
+
+1. Download sonic-buildimage environment.
+  - Run "git clone https://github.com/Azure/sonic-buildimage".
+  - cd to sonic-buildimage and run "git submodule update --init --recursive".
+2. Build kernel
+  - cd ./src/sonic-linux-kernel
+  - Copy patches and series from patch/kernel of this release to 
+    sonic-linux-kernel/patch.
+  - Build kernel by "make".
+  - The built kernel package, linux-image-3.16.0-6-amd64_3.16.51-3+deb8u1_amd64.deb
+    , is generated.
+3. Build installer 
+  - Change directory back to sonic-buildimage/.
+  - Get onie_installer-accton-AS5712-54X.patch" from patch/installer.
+  - Change setting for AS5712-54X by patching build_image.sh.
+    "patch -p1 < onie_installer-accton-AS5712-54X.patch"
+    !!NOTICE, patching onie_installer-accton-AS5712-54X.patch comments out the
+    "git status" checking at build_image.sh.
+  - The account and password of installed OS can be given at rules/config.
+    The default user and password are "admin" & "YourPaSsWoRd" respectively.
+  - Run "make configure PLATFORM=broadcom"
+  - Copy the built kernel debian package to target/debs/.
+    The file is linux-image-3.16.0-6-amd64_*_amd64.deb under directory
+    src/sonic-linux-kernel/.
+  - Run "make target/sonic-generic.bin"
+  - Get the installer, target/sonic-generic.bin, to target machine and install.
+
+All Linux kernel code is licensed under the GPLv1. All other code is
+licensed under the GPLv3. Please see the LICENSE file for copies of
+both licenses.
+
+The code for integacting with Accton AS5712-54X has 2 parts, 
+kernel drivers and operational script. 
+The kernel drivers of peripherals are under module/ directory.
+1.  These drivers are patched into kernel by 
+    driver-patches-for-accton-as5712-fan-psu-cpld.patch
+    Or you can build the driver under module/ by setting environment variable, 
+    KERNEL_SRC, to proper linux built directory and run make. 
+    It may be sonic-linux-kernel/linux-3.*/debian/build/build_amd64_none_amd64/.
+2.  A operational script, accton_as5712_util.py, for device initializatian and 
+    peripheral accessing should be installed at /usr/bin. 
+    This script is generated by onie_installer-accton-AS5712-54X.patch.
+    It's done by patching onie_installer-accton-AS5712-54X.patch at build-image.
+    Run "accton_as5712_util.py install" to install drivers.
+
+To initialize the system, run "accton_as5712_util.py install".
+To clean up the drivers & devices, run "accton_as5712_util.py clean".
+To dump information of sensors, run "accton_as5712_util.py show".
+To dump SFP EEPROM, run "accton_as5712_util.py sff".
+To set fan speed, run "accton_as5712_util.py set fan".
+To enable/disable SFP emission, run "accton_as5712_util.py set sfp".
+To set system LEDs' color, run "accton_as5712_util.py set led"
+For more information, run "accton_as5712_util.py --help".
+
+====================================================================
+Besides applying accton_as5712_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+System LED:
+    There are 5 system LEDs at the lower-left corner of front panel.
+    They are  loc, diag, fan, ps1, and ps2. 
+    The sysfs interface color mappings are as follows:
+    Brightness:
+        0 => off
+        1 => green
+        2 => amber
+        3 => red
+        4 => blue
+    But not all colors are available for each LED.
+
+Fan Control:
+    There are 10 fans inside 5 fan modules.
+    All fans share 1 duty setting, ranged from 0~100.
+
+Thermal sensers:
+    3 temperature sensors are controlled by the lm75 kernel modules. 
+
+PSUs:
+    There 2 power supplies slot at the left/right side of the back.
+    Once if a PSU is not plugged, the status of it is shown failed.
+
+There are 48 SFP+ and 6 QSFP modules are equipped. 
+Before operating on PSU and QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+The late Sonic building scripts, pushed @Dec 5 2016, will automatically 
+create a docker container and run building process under it.
+User is not necessary to handle docker environment creation.
+
+1. Download sonic-buildimage environment.
+  - Run "git clone https://github.com/Azure/sonic-buildimage".
+  - cd to sonic-buildimage and run "git submodule update --init --recursive".
+2. Build kernel
+  - cd ./src/sonic-linux-kernel
+  - Copy patches and series from patch/kernel of this release to 
+    sonic-linux-kernel/patch.
+  - Build kernel by "make".

+
+All Linux kernel code is licensed under the GPLv1. All other code is
+licensed under the GPLv3. Please see the LICENSE file for copies of
+both licenses.
+
+The code for integacting with Accton AS5712-54X has 2 parts, 
+kernel drivers and operational script. 
+The kernel drivers of peripherals are under module/ directory.
+1.  These drivers are patched into kernel by 
+    driver-patches-for-accton-as5712-fan-psu-cpld.patch
+    Or you can build the driver under module/ by setting environment variable, 
+    KERNEL_SRC, to proper linux built directory and run make. 
+    It may be sonic-linux-kernel/linux-3.*/debian/build/build_amd64_none_amd64/.
+2.  A operational script, accton_as5712_util.py, for device initializatian and 
+    peripheral accessing should be installed at /usr/bin. 
+    This script is generated by onie_installer-accton-AS5712-54X.patch.
+    It's done by patching onie_installer-accton-AS5712-54X.patch at build-image.
+    Run "accton_as5712_util.py install" to install drivers.
+
+To initialize the system, run "accton_as5712_util.py install".
+To clean up the drivers & devices, run "accton_as5712_util.py clean".
+To dump information of sensors, run "accton_as5712_util.py show".
+To dump SFP EEPROM, run "accton_as5712_util.py sff".
+To set fan speed, run "accton_as5712_util.py set fan".
+To enable/disable SFP emission, run "accton_as5712_util.py set sfp".
+To set system LEDs' color, run "accton_as5712_util.py set led"
+For more information, run "accton_as5712_util.py --help".
+
+====================================================================
+Besides applying accton_as5712_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+System LED:
+    There are 5 system LEDs at the lower-left corner of front panel.
+    They are  loc, diag, fan, ps1, and ps2. 
+    The sysfs interface color mappings are as follows:
+    Brightness:
+        0 => off
+        1 => green
+        2 => amber
+        3 => red
+        4 => blue
+    But not all colors are available for each LED.
+
+Fan Control:
+    There are 10 fans inside 5 fan modules.
+    All fans share 1 duty setting, ranged from 0~100.
+
+Thermal sensers:
+    3 temperature sensors are controlled by the lm75 kernel modules. 
+
+PSUs:
+    There 2 power supplies slot at the left/right side of the back.
+    Once if a PSU is not plugged, the status of it is shown failed.
+
+There are 48 SFP+ and 6 QSFP modules are equipped. 
+Before operating on PSU and QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+
+To initialize the system, run "accton_as7712_util.py install".
+To clean up the drivers & devices, run "accton_as7712_util.py clean".
+To dump information of sensors, run "accton_as7712_util.py show".
+To dump SFP EEPROM, run "accton_as7712_util.py sff".
+To set fan speed, run "accton_as7712_util.py set fan".
+To enable/disable SFP emission, run "accton_as7712_util.py set sfp".
+To set system LEDs' color, run "accton_as7712_util.py set led"
+For more information, run "accton_as7712_util.py --help".
+
+====================================================================
+Besides applying accton_as7712_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+LED controls can be found under /sys/class/leds. The sysfs interface
+color mappings are as follows:
+Brightness:
+  0 => off
+  1 => green
+  2 => amber
+  3 => red
+  4 => blue
+
+There are 5 system LEDs, loc, diag, fan, ps1, and ps2. 
+They are lit automatically by CPLD, but the loc and diag.
+The loc led has only 1 color, blue.
+The diag one has 3 colors: red, amber, and green.
+
+Fan controls can be found in /sys/bus/i2c/devices/2-0066.
+There are 12 fans inside 6 fan modules.
+All fans share 1 duty setting, ranged from 0~100.
+
+Three temperature sensors are controlled by the lm75 kernel modules. 
+They should already be visible under /sys/bus/i2c/drivers/lm75/.
+
+Two power supplies are controlled by the CPLD. 
+Here provide their status under
+/sys/bus/i2c/devices/10-0050 and /sys/bus/i2c/devices/11-0053.
+
+There are 32 QSFP+ modules are equipped. 
+Apply "accton_as7712_util.py show" to get their status. 
+Apply "accton_as7712_util.py set sfp" to turn on/off light transmission.
+Apply "accton_as7712_util.py sff" to dump EEPROM information.
+Before operating on that QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+ * Virtual registers.
+ * Useful to support attributes which are not supported by standard PMBus
+ * registers but exist as manufacturer specific registers on individual chips.
+ * Must be mapped to real registers in device specific code.
+ *
+ * Semantics:
+ * Virtual registers are all word size.
+ * READ registers are read-only; writes are either ignored or return an error.
+ * RESET registers are read/write. Reading reset registers returns zero
+ * (used for detection), writing any value causes the associated history to be
+ * reset.
+ * Virtual registers have to be handled in device specific driver code. Chip
+ * driver code returns non-negative register values if a virtual register is
+ * supported, or a negative error code if not. The chip driver may return
+ * -ENODATA or any other error code in this case, though an error code other
+ * than -ENODATA is handled more efficiently and thus preferred. Either case,
+ * the calling PMBus core code will abort if the chip driver returns an error
+ * code when reading or writing virtual registers.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.
+
+
+
+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+

+Arista platform support for SONiC
+=================================
+

+
+This program is free software: you can redistribute it and/or modify
+it under the terms of the GNU General Public License as published by

+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+GNU General Public License for more details.
+
+You should have received a copy of the GNU General Public License
+along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+## License
+
+All linux kernel code is licensed under the GPLv2. All other code is
+licensed under the GPLv3. Please see the LICENSE file for copies of
+both licenses.
+
+## Purpose
+
+This package contains kernel drivers, a python library and a python binary to
+provide platform support for Arista switches.
+
+The `arista` tool will identify the platform on which it is running and will
+then load and initialise the required kernel drivers. Once initialised, the
+system will expose transceivers, leds, fans, temperature sensors and gpios
+through the sysfs.
+
+## Supported platforms
+
+The following platforms are currently supported,
+
+ - DCS-7050QX-32
+ - DCS-7050QX-32S
+ - DCS-7060CX-32
+ - DCS-7260CX3-64
+
+Some platforms will require some custom kernel patches.
+They are available on the Azure/sonic-linux-kernel repository.
+
+## Usage
+
+This repository contains both a `systemd` and `LSB` init script to properly
+integrate with the system startup and shutdown.
+
+Alternatively the `arista` tool can be used in standalone to load and unload
+the platform support.
+
+```
+   arista --help
+```
+
+Since the python library knows about the current platform, it can provides a
+common and unified implementation of the SONiC plugins.
+Currently supports `eeprom`, `sfputil` and `led_control`.
+
+The python library and tools are python2 and python3 compatible.
+
+## Drivers
+
+The kernel drivers in this repository have currently been tested against a
+3.16 and 3.18 based kernel image.
+
+### scd-hwmon vs sonic-support-driver
+
+The `scd-hwmon` is the newer implementation of the scd driver and is used
+for all supported platforms except `DCS-7050QX-32` and `DCS-7050QX-32S` which
+use `sonic-support driver`.
+
+When the `scd-hwmon` driver is loaded, the various gpios and resets can be set
+and unset by writing into the sysfs file.
+The meaning of the value `0` or `1` read from or written to is determined by
+the name of the sysfs entry.
+
+```
+cd /sys/module/scd/drivers/pci:scd/<pciAddr>/
+echo 1 > switch_chip_reset
+```
+
+When the legacy `sonic-support-driver` is in use, the gpios and resets behave
+according to the gpio subsystem of the kernel. The driver will properly set
+`value` and `active_low`, whereas `direction` must be set to `out` when
+setting the gpio and to `in` when reading it. Read only entries don't have
+a `direction` file.
+
+```
+cd /sys/module/scd/drivers/pci:scd/<pciAddr>/
+echo out > switch_chip_reset/direction
+echo 1 > switch_chip_reset/value
+echo 0 > switch_chip_reset/value
+```
+
+## Components
+
+This section describes how to interact with the various components exposed by
+the kernel drivers.
+In order to see them, the platform must be successfully initialized.
+
+The following sections describe how to manually interact with the components.
+Examples shown may differ across platforms but the logic stays the same.
+
+### LEDs
+
+LED entries can be found under `/sys/class/leds`. Since the sysfs interface
+for LEDs is not very expressive, the brightness field is used here
+to toggle between off and different colors. The brightness to LED
+color mappings are as follows (0 maps to off for all LEDs):
+
+```
+status, fan_status, psu1, psu2:
+  0 => off
+  1 => green
+  2 => red
+
+beacon:
+  1+ => blue
+
+qsfp:
+  1 => green
+  2 => yellow
+
+fan:
+  1 => green
+  2 => red
+  3 => yellow
+```
+
+Given that this repository is primarily aimed at running on SONiC, an
+implementation of the `led_control` plugin is available under
+`arista.utils.sonic_leds`. It requires access to the `port_config.ini` file to
+translate from `interface name` to `front panel port`.
+
+### Fans
+
+Fans are exposed under `/sys/class/hwmon/*` and respect the
+[sysfs-interface](https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface)
+guidelines.
+
+This repository provides the kernel modules to handle the fans.
+
+### Temperature sensors
+
+Temperature sensors are exposed under `/sys/class/hwmon/*` and also respect
+the [sysfs-interface](https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface).
+
+They are all managed by linux standard modules like `lm73` and `max6658`.
+
+### Power supplies
+
+Power supplies and power controllers can be managed by the kernel's
+generic `pmbus` module. Assuming the pmbus module was compiled into the
+kernel.
+
+Some power supplies may need kernel patches against the `pmbus` driver.
+
+### System EEPROM
+
+The system eeprom contains platform specific information like the `SKU`, the
+`serial number` and the `base mac address`.
+
+The way to read the system eeprom from a platform can differ from one SKU to the
+other.
+The most reliable way to get this information is by issuing `arista syseeprom`
+
+In the case of SONiC the module `arista.utils.sonic_eeprom` provide the plugin
+implementation.
+
+### Transceivers - QSFPs / SFPs
+
+Currently only platforms with QSFP+ and SFP+ ports are supported.
+These transceivers provide 2 kind of information.
+
+#### Pins
+
+The first piece of information is obtained from the transceiver physical pins.
+ - QSFP: present, reset, low power mode, interrupt, module select
+ - SFP: present, rxlos, txfault, txdisable
+
+These knobs are accessible under `/sys/module/scd/drivers/pci:scd/.../`
+The name of the entries follow this naming `<type><id>_<pin>`
+For example `qsfp2_reset` or `sfp66_txdisable`.
+
+See [this section](#scd-hwmon-vs-sonic-support-driver) on how to use them.
+
+#### Eeproms
+
+The second piece of information provided by a transceiver is the content of its
+`eeprom`. It is accessible via `SMBus` at the fixed address `0x50`.
+
+On linux, an unoffical module called `sff_8436_eeprom` can handle such devices.
+The arista initialisation library takes care of loading the module for all the
+transceivers.
+They should then all be available under
+`/sys/module/sff_8436_eeprom/drivers/i2c:sff8436`
+
+After instantiation, the EEPROM information can be read like so:
+
+```
+root@sonic# hexdump -C /sys/bus/i2c/devices/19-0050/eeprom

+```
+
+Before being read, the QSFP+ modules must be taken out of reset and
+have their module select signals asserted. This can be done through
+the GPIO interface.
+
+### QSFP - SFP multiplexing
+
+On the `DCS-7050QX-32S`, the first QSFP port and the 4 SFP ports are multiplexed.
+To choose between one or the other, write into the sysfs file located under
+`/sys/modules/scd/drivers/pci:scd/.../mux_sfp_qsfp`
+
+### GPIOs and resets
+
+Most of the GPIOs are exposed by the `scd-hwmon` and the `sonic-support-driver`.
+They should be available under `/sys/module/scd/drivers/pci:scd/.../`.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.
+
+
+
+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ * SCD driver.
+ *
+ * When a PCI SCD device is detected, this driver initializes the PCI device and
+ * maps its memory region 0 into virtual memory, but it delays registering an
+ * interrupt handler for the device.  Instead, it creates several device attribute
+ * files:
+ *
+ *   interrupt_status_offset
+ *   interrupt_mask_read_offset
+ *   interrupt_mask_set_offset
+ *   interrupt_mask_clear_offset
+ *   interrupt_mask
+ *   interrupt_mask_powerloss
+ *   interrupt_mask_ardma
+ *   crc_error_irq
+ *   crc_error_panic
+ *   ptp_high_offset
+ *   ptp_low_offset
+ *   msi_rearm_offset
+ *   interrupt_irq
+ *   power_loss
+ *   ardma_offset
+ *   interrupt_poll
+ *   nmi_port_io_p
+ *   nmi_control_reg_addr
+ *   nmi_control_mask
+ *   nmi_status_reg_addr
+ *   nmi_status_mask
+ *   nmi_gpio_status_reg_addr
+ *   nmi_gpio_status_mask
+ *   init_trigger
+ *
+ * which will appear in the directory /sys/devices/pciAAAA:BB/AAAA:BB:CC.D/.
+ *
+ * The first 13 are read/write.  The offset within memory region 0 of the interrupt
+ * status and interrupt mask registers can be configured by writing their values to
+ * the first four attribute files.  The mask of valid bits in the interrupt status
+ * register can be set by writing its value to the fifth file (all 'invalid' bits
+ * are expected always to be zero).  To handle
+ * the CRC error interrupt (completely separate from the normal interrupt line),
+ * write the IRQ number to crc_error_irq.  Similarly, if the device interrupt is not
+ * the PCI interrupt, then write the interrupt_irq file. To raise a kernel panic
+ * upon a crc interrupt, set crc_error_panic to 1.
+ *
+ * The values written to each of these files should be in ASCII decimal.  Reading
+ * from any of these files will return the value last written, also in ASCII decimal.
+ *
+ * After the other files have been written, writing (anything) to the
+ * 'init_trigger' file will cause initialization of the driver to continue, creating
+ * up to 32 UIO devices (/dev/uio<n>), one for each bit that was set in the
+ * interrupt_mask, registering an interrupt handler. Reading from 'init_trigger'
+ * returns a positive initialization error if one occurred, or 0 for success.
+ * After successful initialization attribute files become read only. Attempts at
+ * changing their values results in a warning.
+ *
+ * Each UIO device corresponds to a bit in the interrupt status/mask registers.
+ * Reads on one of the UIO device files will complete when an interrupt has occurred
+ * for that bit, at which point that bit will have been added to the interrupt mask.
+ * It is up to the userspace code to remove that bit from the interrupt mask when it
+ * has handled the interrupt and cleared the interrupt at source.
+ *
+ * NMI data is also stored per-scd. nmi_priv points to the scd_dev_priv for the
+ * scd responsible for registering and maintaining the nmi handler. Only
+ * one scd is configured to handle the nmi. Userspace code (the scd agent) is trusted
+ * to pick the correct scd and correctly write to the corresponding attribute files.
+ * nmi_priv is set when writing to the nmi_control_reg_addr file, attempts by other
+ * devices to change nmi_priv after this point is an error. There is no protection
+ * against multiple entities concurrently initializing scd attributes.

+Dell S6100 64x40G support 
+------------------------
+
+summary:-
+S6100 has 64 x 40G port capacity
+S6100 supports 4 IO Modules which are pluggable. Below section covers how to power on IO modules
+and initialize the device drivers and configure necessary mux to send traffic.
+
+
+Necessary drivers and scripts to package 
+
+1) Users are expected to build necessary drivers for kernel and package to acess it on the target
+
+    a) Mgmt phy driver  
+      This supports BCM 54616 phy driver ( enable CONFIG_IGB in kernel config)
+    b) driver-support-sff-8436-eeprom.patch 
+    c) driver-support-sff-8436-eeprom-update.patch
+    This driver supports QSFP EEPROM
+    d) dell_s6100_iom_cpld.ko   
+    This driver provides support for cpld on 4 x 40Gig-IOM modules
+    e) i2c_mux_pca954x.ko
+    This driver provides support for i2c mux/switch (pca954x)
+    f) dell_s6100_lpc.ko
+    This driver porivide support for reading all the platform info from SMF. 
+
+
+2) Users are also expected to package below scripts for platform initialization and i2c tree creation 
+
+    a) iom_power.sh
+    This script is used to power on IO modules on S6100
+    b) io_rd_wr.py
+This script is generic LPC/io read/write utility (can also access system cpld)
+
+steps to platform initialization (Tested with 3.16)
+
+1) After power up of S6100 
+
+     a) power up the io modules by executing (./iom_power.sh)
+     b) insert i2c_mux_pca954x.ko,dell_s6100_iom_cpld.ko,dell_s6100_lpc.ko 
+
+    Above 2 steps can be called by including them in below 2 step
+
+2) Build i2c device tree/device initialization by calling below script
+
+    ./s6100_platform_init.sh
+
+3) IOM cpld devices are created under "/sys/bus/i2c/drivers/dell_s6100_iom_cpld/"
+   QSFP handles via sysfs i2c bus #( 15,16,17,18-003e)
+   iom_cpld_vers -- Displays CPLD version(RO)
+   qsfp_lpmode   -- lpmode settings(RW)
+   qsfp_modprs   -- modules presence (RO)
+   qsfp_reset    -- reset settings (RW)
+
+    ls /sys/bus/i2c/drivers/dell_s6100_iom_cpld/15-003e/
+    driver/        iom_cpld_vers  modalias       name           power/         qsfp_lpmode    qsfp_modprs    qsfp_reset     subsystem/     uevent
+
+4) step 2 script also builds/attach sfp device tress in sysfs
+   
+    Example for reading EEPROM data

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    {one line to give the program's name and a brief idea of what it does.}
+    Copyright (C) {year}  {name of author}
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    {project}  Copyright (C) {year}  {fullname}
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+ - conf/
+ > Platform configure files.
+
+## Kernel modules and drivers
+
+The driver for interacting with Ingrasys S8810-32Q is contained in the I2C 
+kernel module and initialization script. The initialization script loads 
+the modules in the correct order. It has been built and tested against
+the Linux 3.16 kernel. 
+
+The initialization script will modprobe the needed modules, navigate to the 
+module's device directory in sysfs, and write configuration data to 
+the kernel module.
+
+### IGB
+
+This is OOB Ports on front panel for management plane.
+
+The IGB module must be loaded first on Ingrasys S8810-32Q platform.
+
+### I2C i801
+
+The I2C i801 on Ingrasys S8810-32Q can be found in
+`/sys/bus/i2c/devices/i2c-0/`
+
+This is I2C bus for Clock Gen, DIMM channel and digital potentiometers. 
+
+The i801 module must be loaded second on Ingrasys S8810-32Q.
+
+### I2C iSMT
+
+The I2C iSMT module on S8810-32Q can be found in
+`/sys/bus/i2c/devices/i2c-1/`
+
+This is I2C bus for CPLD, HWM, power controller and I2C Switches.
+
+The i801 module must be loaded third on Ingrasys S8810-32Q.
+
+### I2C PCA9548
+The PCA9548 module on S8810-32Q can be found in
+`/sys/bus/i2c/devices/i2c-2/` , `/sys/bus/i2c/devices/i2c-3/`, 
+`/sys/bus/i2c/devices/i2c-4/`, `/sys/bus/i2c/devices/i2c-5/`,
+`/sys/bus/i2c/devices/i2c-6/`, `/sys/bus/i2c/devices/i2c-7/`,
+`/sys/bus/i2c/devices/i2c-8/`, `/sys/bus/i2c/devices/i2c-9/`.
+
+The pca9548 module for zQSFP module get/set functions, PSU information, 
+fan status and EEPROM.
+
+## Hardware components
+
+The hardware components are initialized in the init script on S8810-32Q. 
+The following describes manual initialization as well as interaction.
+The examples below are just for Ingrasys S8810-32Q platform.
+
+### Hardware initialization
+
+When the sonic-platform-ingrasys-s8810-32q package is installed on the S8810-32Q,
+it is automatically initialized. If you want to manual initialization, the 
+utility command usage as follows:
+```
+    i2c_utils.sh i2c_init
+```
+
+### EEPROM
+
+The EEPROM is including the board SKU, model name, vendor name, serial number, 
+and other information can be accessed with the specific eeprom kernel module.
+After using `modprobe eeprom_mb` to detect the eeprom, it will show up in sysfs.
+
+The hexdump utility can be used to decode the raw output of the EEPROM. 
+For example,
+```
+    bash# echo "mb_eeprom 0x54" > /sys/bus/i2c/devices/i2c-9/new_device
+    bash# cat /sys/bus/i2c/drivers/mb_eeprom/9-0054/eeprom | hexdump -C
+```
+
+### Front panel LEDs
+
+LEDs can be setup on/off by using i2c utility `/usr/sbin/i2c_utils.sh`.
+Utility function command usage as follows:
+
+```
+Status LED:
+    i2c_utils.sh i2c_sys_led green|amber on|off
+
+Fan status LED:
+    i2c_utils.sh i2c_fan_led green|amber on|off
+
+PSU1 status LED:
+    i2c_utils.sh i2c_psu1_led green|amber on|off
+
+PSU2 status LED:
+    i2c_utils.sh i2c_psu2_led green|amber on|off
+
+```
+QSFP Module Port LEDs control by ASIC library.
+
+
+### Fan speed
+
+Fan speed are controlled by the w83795 kernel module. 
+It can be found in `/sys/class/hwmon/hwmon1/device/`.
+If they were compiled as modules, you will need to modprobe w83795 for
+their sysfs entries to show up. Each fan has an `fan<N>_input` file 
+for reading the fan speed. And `pwm1` setting fan1 to fan4, 
+`pwm2` setting fan5 to fan8.
+
+There is docker-platform-monitor container installed fancontrol package that can
+automatic control platform fan speed.
+
+
+### Temperature sensors
+
+Temperature sensors are controlled by the w83795 kernel
+module. It can be found in `/sys/class/hwmon/hwmon1/device/`. 
+If they were compiled as modules, then you will need to modprobe w83795 for
+their sysfs entries to show up.
+`temp1_input` is front MAC temperature sensor. `temp2_input` is rear MAC 
+temperature sensor. 
+
+There is docker-platform-monitor container installed lm-sensors package that can
+monitor platform temperature. And `sensors` command can show each 
+temperature sensors status.
+
+### Power supplies
+
+Power supplies status and its EEPROM info can be used i2c utility 
+`/usr/sbin/i2c_utils.sh` to get.
+The usage as follows:
+```
+PSU EEPROM:
+    i2c_utils.sh i2c_psu_eeprom_get
+    hexdump -C psu0.rom
+    hexdump -C psu1.rom
+
+PSU Status:
+    i2c_utils.sh i2c_psu_status
+```
+
+### QSFPs
+QSFP modules are managed by the pca9548 kernel driver.
+The i2c utility `/usr/sbin/i2c_utils.sh` can be used to get status and
+module EEPROM informations.
+The usage as follows:
+```
+QSFP EEPROM:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+
+QSFP Insert Event:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+    0 => not insert
+    1 => inserted
+```

+
+## Kernel modules and drivers
+
+The driver for interacting with Ingrasys S8900-54XC is contained in the I2C 
+kernel module and initialization script. The initialization script loads 
+the modules in the correct order. It has been built and tested against
+the Linux 3.16 kernel. 
+
+The initialization script will modprobe the needed modules, navigate to the 
+module's device directory in sysfs, and write configuration data to 
+the kernel module.
+
+### IGB
+
+This is OOB Ports on front panel for management plane.
+
+The IGB module must be loaded first on Ingrasys S8900-54XC platform.
+
+### I2C i801
+
+The I2C i801 on Ingrasys S8900-54XC can be found in
+`/sys/bus/i2c/devices/i2c-0/`
+
+This is I2C bus for Clock Gen, DIMM channel and digital potentiometers. 
+
+The i801 module must be loaded second on Ingrasys S8900-54XC.
+
+### I2C iSMT
+
+The I2C iSMT module on S8900-54XC can be found in
+`/sys/bus/i2c/devices/i2c-1/`
+
+This is I2C bus for CPLD, HWM, power controller and I2C Switches.
+
+The i801 module must be loaded third on Ingrasys S8900-54XC.
+
+### I2C PCA9548
+The PCA9548 module on S8900-54XC can be found in
+`/sys/bus/i2c/devices/i2c-2/` , `/sys/bus/i2c/devices/i2c-3/`, 
+`/sys/bus/i2c/devices/i2c-4/`, `/sys/bus/i2c/devices/i2c-5/`,
+`/sys/bus/i2c/devices/i2c-6/`, `/sys/bus/i2c/devices/i2c-7/`,
+`/sys/bus/i2c/devices/i2c-8/`, `/sys/bus/i2c/devices/i2c-9/`.
+
+The pca9548 module for zQSFP module get/set functions, PSU information, 
+fan status and EEPROM.
+
+## Hardware components
+
+The hardware components are initialized in the init script on S8900-54XC. 
+The following describes manual initialization as well as interaction.
+The examples below are just for Ingrasys S8900-54XC platform.
+
+### Hardware initialization
+
+When the sonic-platform-ingrasys-s8900-54xc package is installed on the S8900-54XC,
+it is automatically initialized. If you want to manual initialization, the 
+utility command usage as follows:
+```
+    i2c_utils.sh i2c_init
+```
+
+### EEPROM
+
+The EEPROM is including the board SKU, model name, vendor name, serial number, 
+and other information can be accessed with the specific eeprom kernel module.
+After using `modprobe eeprom_mb` to detect the eeprom, it will show up in sysfs.
+
+The hexdump utility can be used to decode the raw output of the EEPROM. 
+For example,
+```
+    bash# echo "mb_eeprom 0x54" > /sys/bus/i2c/devices/i2c-9/new_device
+    bash# cat /sys/bus/i2c/drivers/mb_eeprom/9-0054/eeprom | hexdump -C
+```
+
+### Front panel LEDs
+
+LEDs can be setup on/off by using i2c utility `/usr/sbin/i2c_utils.sh`.
+Utility function command usage as follows:
+
+```
+Status LED:
+    i2c_utils.sh i2c_sys_led green|amber on|off
+
+Fan status LED:
+    i2c_utils.sh i2c_fan_led green|amber on|off
+
+PSU1 status LED:
+    i2c_utils.sh i2c_psu1_led green|amber on|off
+
+PSU2 status LED:
+    i2c_utils.sh i2c_psu2_led green|amber on|off
+
+```
+QSFP Module Port LEDs control by ASIC library.
+
+
+### Fan speed
+
+Fan speed are controlled by the w83795 kernel module. 
+It can be found in `/sys/class/hwmon/hwmon1/device/`.
+If they were compiled as modules, you will need to modprobe w83795 for
+their sysfs entries to show up. Each fan has an `fan<N>_input` file 
+for reading the fan speed. And `pwm1` setting fan1 to fan4, 
+`pwm2` setting fan5 to fan8.
+
+There is docker-platform-monitor container installed fancontrol package that can
+automatic control platform fan speed.
+
+
+### Temperature sensors
+
+Temperature sensors are controlled by the w83795 kernel
+module. It can be found in `/sys/class/hwmon/hwmon1/device/`. 
+If they were compiled as modules, then you will need to modprobe w83795 for
+their sysfs entries to show up.
+`temp1_input` is front MAC temperature sensor. `temp2_input` is rear MAC 
+temperature sensor. 
+
+There is docker-platform-monitor container installed lm-sensors package that can
+monitor platform temperature. And `sensors` command can show each 
+temperature sensors status.
+
+### Power supplies
+
+Power supplies status and its EEPROM info can be used i2c utility 
+`/usr/sbin/i2c_utils.sh` to get.
+The usage as follows:
+```
+PSU EEPROM:
+    i2c_utils.sh i2c_psu_eeprom_get
+    hexdump -C psu0.rom
+    hexdump -C psu1.rom
+
+PSU Status:
+    i2c_utils.sh i2c_psu_status
+```
+
+### QSFPs
+QSFP modules are managed by the pca9548 kernel driver.
+The i2c utility `/usr/sbin/i2c_utils.sh` can be used to get status and
+module EEPROM informations.
+The usage as follows:
+```
+QSFP EEPROM:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+
+QSFP Insert Event:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+    0 => not insert
+    1 => inserted
+```

+## Kernel modules and drivers
+
+The driver for interacting with Ingrasys S8900-64XC is contained in the I2C 
+kernel module and initialization script. The initialization script loads 
+the modules in the correct order. It has been built and tested against
+the Linux 3.16 kernel. 
+
+The initialization script will modprobe the needed modules, navigate to the 
+module's device directory in sysfs, and write configuration data to 
+the kernel module.
+
+### IGB
+
+This is OOB Ports on front panel for management plane.
+
+The IGB module must be loaded first on Ingrasys S8900-64XC platform.
+
+### I2C i801
+
+The I2C i801 on Ingrasys S8900-64XC can be found in
+`/sys/bus/i2c/devices/i2c-0/`
+
+This is I2C bus for Clock Gen, DIMM channel and digital potentiometers. 
+
+The i801 module must be loaded second on Ingrasys S8900-64XC.
+
+### I2C iSMT
+
+The I2C iSMT module on S8900-64XC can be found in
+`/sys/bus/i2c/devices/i2c-1/`
+
+This is I2C bus for CPLD, HWM, power controller and I2C Switches.
+
+The i801 module must be loaded third on Ingrasys S8900-64XC.
+
+### I2C PCA9548
+The PCA9548 module on S8900-64XC can be found in
+`/sys/bus/i2c/devices/i2c-2/` , `/sys/bus/i2c/devices/i2c-3/`, 
+`/sys/bus/i2c/devices/i2c-4/`, `/sys/bus/i2c/devices/i2c-5/`,
+`/sys/bus/i2c/devices/i2c-6/`, `/sys/bus/i2c/devices/i2c-7/`,
+`/sys/bus/i2c/devices/i2c-8/`, `/sys/bus/i2c/devices/i2c-9/`.
+
+The pca9548 module for zQSFP module get/set functions, PSU information, 
+fan status and EEPROM.
+
+## Hardware components
+
+The hardware components are initialized in the init script on S8900-64XC. 
+The following describes manual initialization as well as interaction.
+The examples below are just for Ingrasys S8900-64XC platform.
+
+### Hardware initialization
+
+When the sonic-platform-ingrasys-s8900-64xc package is installed on the S8900-64XC,
+it is automatically initialized. If you want to manual initialization, the 
+utility command usage as follows:
+```
+    i2c_utils.sh i2c_init
+```
+
+### EEPROM
+
+The EEPROM is including the board SKU, model name, vendor name, serial number, 
+and other information can be accessed with the specific eeprom kernel module.
+After using `modprobe eeprom_mb` to detect the eeprom, it will show up in sysfs.
+
+The hexdump utility can be used to decode the raw output of the EEPROM. 
+For example,
+```
+    bash# echo "mb_eeprom 0x54" > /sys/bus/i2c/devices/i2c-9/new_device
+    bash# cat /sys/bus/i2c/drivers/mb_eeprom/9-0054/eeprom | hexdump -C
+```
+
+### Front panel LEDs
+
+LEDs can be setup on/off by using i2c utility `/usr/sbin/i2c_utils.sh`.
+Utility function command usage as follows:
+
+```
+Status LED:
+    i2c_utils.sh i2c_sys_led green|amber on|off
+
+Fan status LED:
+    i2c_utils.sh i2c_fan_led green|amber on|off
+
+PSU1 status LED:
+    i2c_utils.sh i2c_psu1_led green|amber on|off
+
+PSU2 status LED:
+    i2c_utils.sh i2c_psu2_led green|amber on|off
+
+```
+QSFP Module Port LEDs control by ASIC library.
+
+
+### Fan speed
+
+Fan speed are controlled by the w83795 kernel module. 
+It can be found in `/sys/class/hwmon/hwmon1/device/`.
+If they were compiled as modules, you will need to modprobe w83795 for
+their sysfs entries to show up. Each fan has an `fan<N>_input` file 
+for reading the fan speed. And `pwm1` setting fan1 to fan4, 
+`pwm2` setting fan5 to fan8.
+
+There is docker-platform-monitor container installed fancontrol package that can
+automatic control platform fan speed.
+
+
+### Temperature sensors
+
+Temperature sensors are controlled by the w83795 kernel
+module. It can be found in `/sys/class/hwmon/hwmon1/device/`. 
+If they were compiled as modules, then you will need to modprobe w83795 for
+their sysfs entries to show up.
+`temp1_input` is front MAC temperature sensor. `temp2_input` is rear MAC 
+temperature sensor. 
+
+There is docker-platform-monitor container installed lm-sensors package that can
+monitor platform temperature. And `sensors` command can show each 
+temperature sensors status.
+
+### Power supplies
+
+Power supplies status and its EEPROM info can be used i2c utility 
+`/usr/sbin/i2c_utils.sh` to get.
+The usage as follows:
+```
+PSU EEPROM:
+    i2c_utils.sh i2c_psu_eeprom_get
+    hexdump -C psu0.rom
+    hexdump -C psu1.rom
+
+PSU Status:
+    i2c_utils.sh i2c_psu_status
+```
+
+### QSFPs
+QSFP modules are managed by the pca9548 kernel driver.
+The i2c utility `/usr/sbin/i2c_utils.sh` can be used to get status and
+module EEPROM informations.
+The usage as follows:
+```
+QSFP EEPROM:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+
+QSFP Insert Event:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+    0 => not insert
+    1 => inserted
+```

+## Licensing terms
+
+The Licensing terms of the files within this project is split 2 parts.
+The Linux kernel is released under the GNU General Public License version 2.
+All other code is released under the GNU General Public License version 3.
+Please see the LICENSE file for copies of both licenses.

+## Contents of this package
+
+ - service/
+ > Service config files for platform initialization and monitoring
+ - utils/
+ > Scripts useful during platform bringup and sysfs function
+ - conf/
+ > Platform configure files.
+
+## Kernel modules and drivers
+
+The driver for interacting with Ingrasys S9100-32X is contained in the I2C 
+kernel module and initialization script. The initialization script loads 
+the modules in the correct order. It has been built and tested against
+the Linux 3.16 kernel. 
+
+The initialization script will modprobe the needed modules, navigate to the 
+module's device directory in sysfs, and write configuration data to 
+the kernel module.
+
+### IGB
+
+This is OOB Ports on front panel for management plane.
+
+The IGB module must be loaded first on Ingrasys S9100-32X platform.
+
+### I2C i801
+
+The I2C i801 on Ingrasys S9100-32X can be found in
+`/sys/bus/i2c/devices/i2c-0/`
+
+This is I2C bus for Clock Gen, DIMM channel and digital potentiometers. 
+
+The i801 module must be loaded second on Ingrasys S9100-32X.
+
+### I2C iSMT
+
+The I2C iSMT module on S9100-32X can be found in
+`/sys/bus/i2c/devices/i2c-1/`
+
+This is I2C bus for CPLD, HWM, power controller and I2C Switches.
+
+The i801 module must be loaded third on Ingrasys S9100-32X.
+
+### I2C PCA9548
+The PCA9548 module on S9100-32X can be found in
+`/sys/bus/i2c/devices/i2c-2/` , `/sys/bus/i2c/devices/i2c-3/`, 
+`/sys/bus/i2c/devices/i2c-4/`, `/sys/bus/i2c/devices/i2c-5/`,
+`/sys/bus/i2c/devices/i2c-6/`, `/sys/bus/i2c/devices/i2c-7/`,
+`/sys/bus/i2c/devices/i2c-8/`, `/sys/bus/i2c/devices/i2c-9/`.
+
+The pca9548 module for zQSFP module get/set functions, PSU information, 
+fan status and EEPROM.
+
+## Hardware components
+
+The hardware components are initialized in the init script on S9100-32X. 
+The following describes manual initialization as well as interaction.
+The examples below are just for Ingrasys S9100-32X platform.
+
+### Hardware initialization
+
+When the sonic-platform-ingrasys-s9100 package is installed on the S9100-32X,
+it is automatically initialized. If you want to manual initialization, the 
+utility command usage as follows:
+```
+    i2c_utils.sh i2c_init
+```
+
+### EEPROM
+
+The EEPROM is including the board SKU, model name, vendor name, serial number, 
+and other information can be accessed with the specific eeprom kernel module.
+After using `modprobe eeprom_mb` to detect the eeprom, it will show up in sysfs.
+
+The hexdump utility can be used to decode the raw output of the EEPROM. 
+For example,
+```
+    bash# echo "mb_eeprom 0x54" > /sys/bus/i2c/devices/i2c-9/new_device
+    bash# cat /sys/bus/i2c/drivers/mb_eeprom/9-0054/eeprom | hexdump -C
+```
+
+### Front panel LEDs
+
+LEDs can be setup on/off by using i2c utility `/usr/sbin/i2c_utils.sh`.
+Utility function command usage as follows:
+
+```
+Status LED:
+    i2c_utils.sh i2c_sys_led green|amber on|off
+
+Fan status LED:
+    i2c_utils.sh i2c_fan_led green|amber on|off
+
+PSU1 status LED:
+    i2c_utils.sh i2c_psu1_led green|amber on|off
+
+PSU2 status LED:
+    i2c_utils.sh i2c_psu2_led green|amber on|off
+
+```
+QSFP Module Port LEDs control by ASIC library.
+
+
+### Fan speed
+
+Fan speed are controlled by the w83795 kernel module. 
+It can be found in `/sys/class/hwmon/hwmon1/device/`.
+If they were compiled as modules, you will need to modprobe w83795 for
+their sysfs entries to show up. Each fan has an `fan<N>_input` file 
+for reading the fan speed. And `pwm1` setting fan1 to fan4, 
+`pwm2` setting fan5 to fan8.
+
+There is docker-platform-monitor container installed fancontrol package that can
+automatic control platform fan speed.
+
+
+### Temperature sensors
+
+Temperature sensors are controlled by the w83795 kernel
+module. It can be found in `/sys/class/hwmon/hwmon1/device/`. 
+If they were compiled as modules, then you will need to modprobe w83795 for
+their sysfs entries to show up.
+`temp1_input` is front MAC temperature sensor. `temp2_input` is rear MAC 
+temperature sensor. 
+
+There is docker-platform-monitor container installed lm-sensors package that can
+monitor platform temperature. And `sensors` command can show each 
+temperature sensors status.
+
+### Power supplies
+
+Power supplies status and its EEPROM info can be used i2c utility 
+`/usr/sbin/i2c_utils.sh` to get.
+The usage as follows:
+```
+PSU EEPROM:
+    i2c_utils.sh i2c_psu_eeprom_get
+    hexdump -C psu0.rom
+    hexdump -C psu1.rom
+
+PSU Status:
+    i2c_utils.sh i2c_psu_status
+```
+
+### QSFPs
+QSFP modules are managed by the pca9548 kernel driver.
+The i2c utility `/usr/sbin/i2c_utils.sh` can be used to get status and
+module EEPROM informations.
+The usage as follows:
+```
+QSFP EEPROM:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+
+QSFP Insert Event:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+    0 => not insert
+    1 => inserted
+```

+ > Platform configure files.
+
+## Kernel modules and drivers
+
+The driver for interacting with Ingrasys S9200-64X is contained in the I2C 
+kernel module and initialization script. The initialization script loads 
+the modules in the correct order. It has been built and tested against
+the Linux 3.16 kernel. 
+
+The initialization script will modprobe the needed modules, navigate to the 
+module's device directory in sysfs, and write configuration data to 
+the kernel module.
+
+### IGB
+
+This is OOB Ports on front panel for management plane.
+
+The IGB module must be loaded first on Ingrasys S9200-64X platform.
+
+### I2C i801
+
+The I2C i801 on Ingrasys S9200-64X can be found in
+`/sys/bus/i2c/devices/i2c-0/`
+
+This is I2C bus for Clock Gen, DIMM channel and digital potentiometers. 
+
+The i801 module must be loaded second on Ingrasys S9200-64X.
+
+### I2C iSMT
+
+The I2C iSMT module on S9200-64X can be found in
+`/sys/bus/i2c/devices/i2c-1/`
+
+This is I2C bus for CPLD, HWM, power controller and I2C Switches.
+
+The i801 module must be loaded third on Ingrasys S9200-64X.
+
+### I2C PCA9548
+The PCA9548 module on S9200-64X can be found in
+`/sys/bus/i2c/devices/i2c-2/` , `/sys/bus/i2c/devices/i2c-3/`, 
+`/sys/bus/i2c/devices/i2c-4/`, `/sys/bus/i2c/devices/i2c-5/`,
+`/sys/bus/i2c/devices/i2c-6/`, `/sys/bus/i2c/devices/i2c-7/`,
+`/sys/bus/i2c/devices/i2c-8/`, `/sys/bus/i2c/devices/i2c-9/`.
+
+The pca9548 module for zQSFP module get/set functions, PSU information, 
+fan status and EEPROM.
+
+## Hardware components
+
+The hardware components are initialized in the init script on S9200-64X. 
+The following describes manual initialization as well as interaction.
+The examples below are just for Ingrasys S9200-64X platform.
+
+### Hardware initialization
+
+When the sonic-platform-ingrasys-s9200-64x package is installed on the S9200-64X,
+it is automatically initialized. If you want to manual initialization, the 
+utility command usage as follows:
+```
+    i2c_utils.sh i2c_init
+```
+
+### EEPROM
+
+The EEPROM is including the board SKU, model name, vendor name, serial number, 
+and other information can be accessed with the specific eeprom kernel module.
+After using `modprobe eeprom_mb` to detect the eeprom, it will show up in sysfs.
+
+The hexdump utility can be used to decode the raw output of the EEPROM. 
+For example,
+```
+    bash# echo "mb_eeprom 0x54" > /sys/bus/i2c/devices/i2c-9/new_device
+    bash# cat /sys/bus/i2c/drivers/mb_eeprom/9-0054/eeprom | hexdump -C
+```
+
+### Front panel LEDs
+
+LEDs can be setup on/off by using i2c utility `/usr/sbin/i2c_utils.sh`.
+Utility function command usage as follows:
+
+```
+Status LED:
+    i2c_utils.sh i2c_sys_led green|amber
+
+Fan status LED:
+    i2c_utils.sh i2c_fan_led green|amber
+
+PSU1 status LED:
+    i2c_utils.sh i2c_psu1_led green|amber
+
+PSU2 status LED:
+    i2c_utils.sh i2c_psu2_led green|amber
+
+```
+QSFP Module Port LEDs control by ASIC library.
+
+
+### Fan speed
+
+Fan speed are controlled by the w83795 kernel module. 
+It can be found in `/sys/class/hwmon/hwmon5/device/`.
+If they were compiled as modules, you will need to modprobe w83795 for
+their sysfs entries to show up. Each fan has an `fan<N>_input` file 
+for reading the fan speed. And `pwm2` setting fan1/fan3/fan5/fan7. 
+
+There is docker-platform-monitor container installed fancontrol package that can
+automatic control platform fan speed.
+
+
+### Temperature sensors
+
+Temperature sensors are controlled by the w83795 kernel
+module. It can be found in `/sys/class/hwmon/hwmon5/device/`. 
+If they were compiled as modules, then you will need to modprobe w83795 for
+their sysfs entries to show up.
+`temp1_input` is front MAC temperature sensor. `temp2_input` is rear MAC 
+temperature sensor. 
+
+There is docker-platform-monitor container installed lm-sensors package that can
+monitor platform temperature. And `sensors` command can show each 
+temperature sensors status.
+
+### Power supplies
+
+Power supplies status and its EEPROM info can be used i2c utility 
+`/usr/sbin/i2c_utils.sh` to get.
+The usage as follows:
+```
+PSU EEPROM:
+    i2c_utils.sh i2c_psu_eeprom_get
+    hexdump -C psu0.rom
+    hexdump -C psu1.rom
+
+PSU Status:
+    i2c_utils.sh i2c_psu_status
+```
+
+### QSFPs
+QSFP modules are managed by the pca9548 kernel driver.
+The i2c utility `/usr/sbin/i2c_utils.sh` can be used to get status and
+module EEPROM informations.
+The usage as follows:
+```
+QSFP EEPROM:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-64]
+
+QSFP Insert Event:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-64]
+    0 => not insert
+    1 => inserted
+```

+ * Virtual registers.
+ * Useful to support attributes which are not supported by standard PMBus
+ * registers but exist as manufacturer specific registers on individual chips.
+ * Must be mapped to real registers in device specific code.
+ *
+ * Semantics:
+ * Virtual registers are all word size.
+ * READ registers are read-only; writes are either ignored or return an error.
+ * RESET registers are read/write. Reading reset registers returns zero
+ * (used for detection), writing any value causes the associated history to be
+ * reset.
+ * Virtual registers have to be handled in device specific driver code. Chip
+ * driver code returns non-negative register values if a virtual register is
+ * supported, or a negative error code if not. The chip driver may return
+ * -ENODATA or any other error code in this case, though an error code other
+ * than -ENODATA is handled more efficiently and thus preferred. Either case,
+ * the calling PMBus core code will abort if the chip driver returns an error
+ * code when reading or writing virtual registers.

+ * I2C EEPROMs from most vendors are inexpensive and mostly interchangeable.
+ * Differences between different vendor product lines (like Atmel AT24C or
+ * MicroChip 24LC, etc) won't much matter for typical read/write access.
+ * There are also I2C RAM chips, likewise interchangeable. One example
+ * would be the PCF8570, which acts like a 24c02 EEPROM (256 bytes).
+ *
+ * However, misconfiguration can lose data. "Set 16-bit memory address"
+ * to a part with 8-bit addressing will overwrite data. Writing with too
+ * big a page size also loses data. And it's not safe to assume that the
+ * conventional addresses 0x50..0x57 only hold eeproms; a PCF8563 RTC
+ * uses 0x51, for just one example.
+ *
+ * Accordingly, explicit board-specific configuration data should be used
+ * in almost all cases. (One partial exception is an SMBus used to access
+ * "SPD" data for DRAM sticks. Those only use 24c02 EEPROMs.)
+ *
+ * So this driver uses "new style" I2C driver binding, expecting to be
+ * told what devices exist. That may be in arch/X/mach-Y/board-Z.c or
+ * similar kernel-resident tables; or, configuration data coming from
+ * a bootloader.
+ *
+ * Other than binding model, current differences from "eeprom" driver are
+ * that this one handles write access and isn't restricted to 24c02 devices.
+ * It also handles larger devices (32 kbit and up) with two-byte addresses,
+ * which won't work on pure SMBus systems.

+ * I2C EEPROMs from most vendors are inexpensive and mostly interchangeable.
+ * Differences between different vendor product lines (like Atmel AT24C or
+ * MicroChip 24LC, etc) won't much matter for typical read/write access.
+ * There are also I2C RAM chips, likewise interchangeable. One example
+ * would be the PCF8570, which acts like a 24c02 EEPROM (256 bytes).
+ *
+ * However, misconfiguration can lose data. "Set 16-bit memory address"
+ * to a part with 8-bit addressing will overwrite data. Writing with too
+ * big a page size also loses data. And it's not safe to assume that the
+ * conventional addresses 0x50..0x57 only hold eeproms; a PCF8563 RTC
+ * uses 0x51, for just one example.
+ *
+ * Accordingly, explicit board-specific configuration data should be used
+ * in almost all cases. (One partial exception is an SMBus used to access
+ * "SPD" data for DRAM sticks. Those only use 24c02 EEPROMs.)
+ *
+ * So this driver uses "new style" I2C driver binding, expecting to be
+ * told what devices exist. That may be in arch/X/mach-Y/board-Z.c or
+ * similar kernel-resident tables; or, configuration data coming from
+ * a bootloader.
+ *
+ * Other than binding model, current differences from "eeprom" driver are
+ * that this one handles write access and isn't restricted to 24c02 devices.
+ * It also handles larger devices (32 kbit and up) with two-byte addresses,
+ * which won't work on pure SMBus systems.

+
+To initialize the system, run "accton_as7712_util.py install".
+To clean up the drivers & devices, run "accton_as7712_util.py clean".
+To dump information of sensors, run "accton_as7712_util.py show".
+To dump SFP EEPROM, run "accton_as7712_util.py sff".
+To set fan speed, run "accton_as7712_util.py set fan".
+To enable/disable SFP emission, run "accton_as7712_util.py set sfp".
+To set system LEDs' color, run "accton_as7712_util.py set led"
+For more information, run "accton_as7712_util.py --help".
+
+====================================================================
+Besides applying accton_as7712_util.py to access peripherals, you can 
+access peripherals by sysfs nodes directly after the installation is run.
+
+LED controls can be found under /sys/class/leds. The sysfs interface
+color mappings are as follows:
+Brightness:
+  0 => off
+  1 => green
+  2 => amber
+  3 => red
+  4 => blue
+
+There are 5 system LEDs, loc, diag, fan, ps1, and ps2. 
+They are lit automatically by CPLD, but the loc and diag.
+The loc led has only 1 color, blue.
+The diag one has 3 colors: red, amber, and green.
+
+Fan controls can be found in /sys/bus/i2c/devices/2-0066.
+There are 12 fans inside 6 fan modules.
+All fans share 1 duty setting, ranged from 0~100.
+
+Three temperature sensors are controlled by the lm75 kernel modules. 
+They should already be visible under /sys/bus/i2c/drivers/lm75/.
+
+Two power supplies are controlled by the CPLD. 
+Here provide their status under
+/sys/bus/i2c/devices/10-0050 and /sys/bus/i2c/devices/11-0053.
+
+There are 32 QSFP+ modules are equipped. 
+Apply "accton_as7712_util.py show" to get their status. 
+Apply "accton_as7712_util.py set sfp" to turn on/off light transmission.
+Apply "accton_as7712_util.py sff" to dump EEPROM information.
+Before operating on that QSFP+, please make sure it is well plugged. 
+Otherwise, operation is going to fail.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    {one line to give the program's name and a brief idea of what it does.}
+    Copyright (C) {year}  {name of author}
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    {project}  Copyright (C) {year}  {fullname}
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+## Contents of this package
+
+ - service/
+ > Service config files for platform initialization and monitoring
+ - utils/
+ > Scripts useful during platform bringup and sysfs function
+ - conf/
+ > Platform configure files.
+
+## Kernel modules and drivers
+
+The driver for interacting with Ingrasys S9130-32X is contained in the I2C 
+kernel module and initialization script. The initialization script loads 
+the modules in the correct order. It has been built and tested against
+the Linux 3.16 kernel. 
+
+The initialization script will modprobe the needed modules, navigate to the 
+module's device directory in sysfs, and write configuration data to 
+the kernel module.
+
+### IGB
+
+This is OOB Ports on front panel for management plane.
+
+The IGB module must be loaded first on Ingrasys S9130-32X platform.
+
+### I2C i801
+
+The I2C i801 on Ingrasys S9130-32X can be found in
+`/sys/bus/i2c/devices/i2c-0/`
+
+This is I2C bus for power monitor, FAN controller, HWM and thermal sensors. 
+
+### I2C PCA9548
+The PCA9548 module on S9130-32X can be found in
+`/sys/bus/i2c/devices/i2c-1/` , `/sys/bus/i2c/devices/i2c-2/`, 
+`/sys/bus/i2c/devices/i2c-3/`, `/sys/bus/i2c/devices/i2c-4/`,
+`/sys/bus/i2c/devices/i2c-5/`, `/sys/bus/i2c/devices/i2c-6/`,
+`/sys/bus/i2c/devices/i2c-7/`, `/sys/bus/i2c/devices/i2c-8/`
+
+The pca9548 module for zQSFP module get/set functions, PSU information, 
+fan status and EEPROM.
+
+## Hardware components
+
+The hardware components are initialized in the init script on S9130-32X. 
+The following describes manual initialization as well as interaction.
+The examples below are just for Ingrasys S9130-32X platform.
+
+### Hardware initialization
+
+When the sonic-platform-ingrasys-s9130-32x package is installed on the S9130-32X,
+it is automatically initialized. If you want to manual initialization, the 
+utility command usage as follows:
+```
+    i2c_utils.sh i2c_init
+```
+
+### EEPROM
+
+The EEPROM is including the board SKU, model name, vendor name, serial number, 
+and other information can be accessed with the specific eeprom kernel module.
+After using `modprobe eeprom_mb` to detect the eeprom, it will show up in sysfs.
+
+The hexdump utility can be used to decode the raw output of the EEPROM. 
+For example,
+```
+    bash# echo "mb_eeprom 0x51" > /sys/bus/i2c/devices/i2c-0/new_device
+    bash# cat /sys/bus/i2c/drivers/mb_eeprom/0-0051/eeprom | hexdump -C
+```
+
+### Front panel LEDs
+
+LEDs can be setup on/off by using i2c utility `/usr/sbin/i2c_utils.sh`.
+Utility function command usage as follows:
+
+```
+Status LED:
+    i2c_utils.sh i2c_sys_led green|amber 
+
+Fan status LED:
+    i2c_utils.sh i2c_fan_led green|amber on|off
+
+PSU1 status LED:
+    i2c_utils.sh i2c_psu1_led green|amber on|off
+
+PSU2 status LED:
+    i2c_utils.sh i2c_psu2_led green|amber on|off
+
+```
+QSFP Module Port LEDs control by ASIC library.
+
+
+### Fan speed
+
+Fan speed are controlled by the w83795 kernel module. 
+It can be found in `/sys/class/hwmon/hwmon5/device/`.
+If they were compiled as modules, you will need to modprobe w83795 for
+their sysfs entries to show up. Each fan has an `fan<N>_input` file 
+for reading the fan speed. And `pwm1` setting fan1 to fan4, 
+`pwm2` setting fan5 to fan8.
+
+There is docker-platform-monitor container installed fancontrol package that can
+automatic control platform fan speed.
+
+
+### Temperature sensors
+
+There is docker-platform-monitor container installed lm-sensors package that can
+monitor platform temperature. And `sensors` command can show each 
+temperature sensors status.
+
+### Power supplies
+
+Power supplies status and its EEPROM info can be used i2c utility 
+`/usr/sbin/i2c_utils.sh` to get.
+The usage as follows:
+```
+PSU EEPROM:
+    i2c_utils.sh i2c_psu_eeprom_get
+    hexdump -C psu0.rom
+    hexdump -C psu1.rom
+
+PSU Status:
+    i2c_utils.sh i2c_psu_status
+```
+
+### QSFPs
+QSFP modules are managed by the pca9548 kernel driver.
+The i2c utility `/usr/sbin/i2c_utils.sh` can be used to get status and
+module EEPROM informations.
+The usage as follows:
+```
+QSFP EEPROM:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+
+QSFP Insert Event:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-32]
+    0 => not insert
+    1 => inserted
+```

+ > Service config files for platform initialization and monitoring
+ - utils/
+ > Scripts useful during platform bringup and sysfs function
+ - conf/
+ > Platform configure files.
+
+## Kernel modules and drivers
+
+The driver for interacting with Ingrasys S9230-64X is contained in the I2C 
+kernel module and initialization script. The initialization script loads 
+the modules in the correct order. It has been built and tested against
+the Linux 3.16 kernel. 
+
+The initialization script will modprobe the needed modules, navigate to the 
+module's device directory in sysfs, and write configuration data to 
+the kernel module.
+
+### IGB
+
+This is OOB Ports on front panel for management plane.
+
+The IGB module must be loaded first on Ingrasys S9230-64X platform.
+
+### I2C i801
+
+The I2C i801 on Ingrasys S9230-64X can be found in
+`/sys/bus/i2c/devices/i2c-0/`
+
+This is I2C bus for power monitor, FAN controller, HWM and thermal sensors. 
+
+### I2C PCA9548
+The PCA9548 module on S9230-64X can be found in
+`/sys/bus/i2c/devices/i2c-1/` , `/sys/bus/i2c/devices/i2c-2/`, 
+`/sys/bus/i2c/devices/i2c-3/`, `/sys/bus/i2c/devices/i2c-4/`,
+`/sys/bus/i2c/devices/i2c-5/`, `/sys/bus/i2c/devices/i2c-6/`,
+`/sys/bus/i2c/devices/i2c-7/`, `/sys/bus/i2c/devices/i2c-8/`
+
+The pca9548 module for CPLD get/set functions, PSU information, 
+fan status and EEPROM.
+
+## Hardware components
+
+The hardware components are initialized in the init script on S9230-64X. 
+The following describes manual initialization as well as interaction.
+The examples below are just for Ingrasys S9230-64X platform.
+
+### Hardware initialization
+
+When the sonic-platform-ingrasys-s9230-64X package is installed on the S9230-64X,
+it is automatically initialized. If you want to manual initialization, the 
+utility command usage as follows:
+```
+    i2c_utils.sh i2c_init
+```
+
+### EEPROM
+
+The EEPROM is including the board SKU, model name, vendor name, serial number, 
+and other information can be accessed with the specific eeprom kernel module.
+After using `modprobe eeprom_mb` to detect the eeprom, it will show up in sysfs.
+
+The hexdump utility can be used to decode the raw output of the EEPROM. 
+For example,
+```
+    bash# echo "mb_eeprom 0x55" > /sys/bus/i2c/devices/i2c-0/new_device
+    bash# cat /sys/bus/i2c/drivers/mb_eeprom/0-0055/eeprom | hexdump -C
+```
+
+### Front panel LEDs
+
+LEDs can be setup on/off by using i2c utility `/usr/sbin/i2c_utils.sh`.
+Utility function command usage as follows:
+
+```
+Status LED:
+    i2c_utils.sh i2c_sys_led green|amber 
+
+Fan status LED:
+    i2c_utils.sh i2c_fan_led green|amber on|off
+
+PSU1 status LED:
+    i2c_utils.sh i2c_psu1_led green|amber on|off
+
+PSU2 status LED:
+    i2c_utils.sh i2c_psu2_led green|amber on|off
+
+```
+QSFP Module Port LEDs control by ASIC library.
+
+
+### Fan speed
+
+Fan speed are controlled by the w83795 kernel module. 
+It can be found in `/sys/class/hwmon/hwmon7/device/`.
+If they were compiled as modules, you will need to modprobe w83795 for
+their sysfs entries to show up. Each fan has an `fan<N>_input` file 
+for reading the fan speed. And `pwm1` setting fan1 to fan4, 
+`pwm2` setting fan5 to fan8.
+
+There is docker-platform-monitor container installed fancontrol package that can
+automatic control platform fan speed.
+
+
+### Temperature sensors
+
+There is docker-platform-monitor container installed lm-sensors package that can
+monitor platform temperature. And `sensors` command can show each 
+temperature sensors status.
+
+### Power supplies
+
+Power supplies status and its EEPROM info can be used i2c utility 
+`/usr/sbin/i2c_utils.sh` to get.
+The usage as follows:
+```
+PSU EEPROM:
+    i2c_utils.sh i2c_psu_eeprom_get
+    hexdump -C psu0.rom
+    hexdump -C psu1.rom
+
+PSU Status:
+    i2c_utils.sh i2c_psu_status
+```
+
+### QSFPs
+QSFP modules are managed by the CPLD 1~5 according to port number.
+The i2c utility `/usr/sbin/i2c_utils.sh` can be used to get status and
+module EEPROM informations.
+The usage as follows:
+```
+QSFP EEPROM:
+    i2c_utils.sh i2c_qsfp_eeprom_get [1-64]
+
