I would suggest adding new APIs to current sff8436Dom class instead of having this new class.
The benefit I can see could be:
-
reduce the duplicated code, there is no reason to have two copies of 'cal_temperature', 'calc_voltage', etc.
-
The threshold is part of the DOM, add new APIs would be more intuitional.

Hi,
Addressed the review comment. Removed the duplicate code and added new APIs in sff8436Dom

To provide a complete solution, I would suggest implementing the same set of APIs also for sff8472.

Hi,
Implemented the same solution for sff8472

maybe this is a code merging issue, I saw some code couldn't run. would you please confirm the test result on your local test bed?

where is this sff8436DomThreshold() defined? shouldn't it been removed?

are you able to decouple the threshold reading and the voltage/temp/bias reading? since the threshold is constant, we don't want to read them in every iteration for voltage/power/bias reading. This will introduce unnecessary load to CPU since I2C access is time-consuming.

Hi,
I have decoupled it correctly this time. Implemented a new function get_transceiver_dom_threshold_info_dict.

This change looks good to me.
One more thing is that in folder https://github.com/Azure/sonic-platform-common/tree/master/sonic_platform_base/sonic_sfp we have copies of all the files in https://github.com/Azure/sonic-platform-common/tree/master/sonic_sfp
The intention to keep this copy is that in the near future(could be next release), we will only keep files under ../sonic_platform_base/sonic_sfp and others will be removed along with plugins.
so please also merge your change to the files under ../sonic_platform_base/sonic_sfp

Hi,
Ported my changes from sonic_sfp to sonic_platform_base/sonic_sfp

This change is added to dump ChannelMonitor Threshold and Module Monitor Threshold values as part of DOM EEPROM dump output.
Added code change in sff8436.py,sfputilshow.py, xcvrd, sfpshow .. etc
Verified the output in following optics
a) AVAGO
b) Finisar
c) DELL
Seeing the following issue of Values not getting dumped properly from day 1
Some channel monitor values are not displayed correctly.
Will raise a seperate issue for that.
