SAI 9.x requires a SYNCD_SHM_SIZE specified otherwise it will default to 64mb which is insufficient for syncd.

E.G. of a few failures seen when insufficient shmem was set

Broadcom recommended using 1gb for DNX devices.

Since currently we don't use SAI9.x on master and 202305 this change won't fix anything until we upgrade the SAI on those branches.

Broadcom requires that programmability_ucode_relative_path is set in SAI11.
This soc property replaces the legacy custom_feature_ucode_path

Without this we get the following error:

* [build] Add build timing report and dependency analysis tools

Add three scripts for build performance instrumentation:

- scripts/build-timing-report.sh: Parse per-package timing from build
  logs (HEADER/FOOTER timestamps), generate sorted duration table,
  phase breakdown, parallelism timeline, and CSV export.

- scripts/build-dep-graph.py: Parse rules/*.mk dependency graph,
  compute critical path, fan-out/fan-in bottleneck analysis, and
  generate DOT/JSON output for visualization.

- scripts/build-resource-monitor.sh: Sample CPU, memory, disk I/O,
  and Docker container count during builds for resource utilization
  analysis.

Add "make build-report" target to slave.mk that runs the timing
report and dependency analysis after a build completes.

Example output from a VS build on 24-core/30GB machine:
- 210 packages built in 53m wall time (173m CPU)
- Max concurrency: 5 (with SONIC_CONFIG_BUILD_JOBS=4)
- Critical path: 14 packages deep (libnl -> libswsscommon -> utilities)
- Top bottleneck: LIBSWSSCOMMON with 48 downstream dependents

…dating udevd rules (#26343)

- Why I did it
On SONiC SmartSwitch platforms with DPUs, systemd-udevd crashes with SIGABRT on every reboot when DPU firmware initialization is slow. During the initramfs boot phase, a standalone systemd-udevd daemon is started to handle device discovery. If DPU firmware takes longer than the 60-second udevadm settle timeout (BlueField-3 DPUs can take 120 seconds each in the failure case when they are stuck), the initramfs cannot stop this udevd before switch_root. The stale process survives into the real system but is never chrooted into the overlayfs root, leaving it with a broken filesystem view. When dpu-udev-manager.sh writes udev rules, the stale udevd detects the change and crashes on an assertion in systemd's chase() path resolution (assert(path_is_absolute(p)) at chase.c:648), because dir_fd_is_root() returns false for a process whose root still points to the initramfs rootfs rather than the overlayfs.

This triggers a systemd issue : systemd/systemd#29559 which maintainers doesn't consider as a bug from systemd side. Raising this fix for our usecase.

- How I did it
Added a kill_stale_udevd() function to dpu-udev-manager.sh that runs before writing the udev rules. It identifies the systemd-managed udevd PID via systemctl show, then kills any other systemd-udevd --daemon process that doesn't match -- these are leftover initramfs instances. If no stale process exists (e.g. DPUs are healthy and the initramfs udevd exited cleanly), the function is a no-op.

- How to verify it
Deploy the image on a SmartSwitch with DPUs in a state where firmware initialization times out (>60s per DPU) by stopping image installation before firmware install step
Reboot the switch
Verify no new systemd-udevd coredumps in /var/core/
Verify the stale process was killed: journalctl -b 0 | grep dpu-udev-manager should show killing stale initramfs udevd PID (systemd udevd is PID )
Verify systemd-udevd.service is healthy: systemctl status systemd-udevd should show active (running)
Verify DPU udev rules were written: cat /etc/udev/rules.d/92-midplane-intf.rules should contain the DPU interface naming rules
