Yocto: L5.15.32

when system start, I find the /sys/module/kernel/parameters/consoleblank is 0

root@imx8qmmek:~# cat /sys/module/kernel/parameters/consoleblank
0

This means the framebuffer auto blank feature will be disabled, but I'm not find when and where set consoleblank to 0 during system start up, can anybody help me about this?

Try to check from bootargs settings for it or in drivers/tty/vt/vt.c
