Hello Fellow Community,

I have a following question. Your help will be really appreciated.

"Kernel expects few params from kernel cmdline from underlying firmware. Is there any mechanism to dynamically update the cmdline updated by firmware (UEFI) during boot time in systemd-boot similar to DT fixup protocol ?"

Example : androidboot.serialno is read from firmware and needs to be appended to kernel commandline



Best Regards,

Harshal Patil
