- What I did
The platform identifier string is used in the reboot script to identify and execute any custom platform specific reboot script.
sonic_platform is used as the kernel parameter to pass the platform identifier string.
- How I did it
In the reboot script, under the case where it is executed by the crash kernel, parse /proc/cmdline and parse sonic_platform value.
- How to verify it
Enable kdump and reboot to operationally enable it.
Using echo c /proc/sysrq-trigger, crash the kernel and observe that the crash kernel executes platform specific reboot script
