Wed, 04 Dec 2024 15:45:01 +0000

drm/log: Introduce a new boot logger to draw the kmsg on the screendrm_log is a simple logger that uses the drm_client API to print thekmsg boot log on the screen. This is not a full replacement to fbcon,as it will only print the kmsg. It will never handle user input, or aterminal because this is better done in userspace.Design decisions: * It uses the drm_client API, so it should work on all drm drivers from the start. * It doesn't scroll the message, that way it doesn't need to redraw the whole screen for each new message. It also means it doesn't have to keep drawn messages in memory, to redraw them when scrolling. * It uses the new non-blocking console API, so it should work well with PREEMPT_RT.This patch also adds a Kconfig menu to select the drm client to use.It can be overwritten on the kernel command line with:drm_client_lib.active=log or drm_client_lib.active=fbdevSigned-off-by: Jocelyn Falempe Reviewed-by: John Ogness # console APIReviewed-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20241204160014.1171469-3-jfalempe@redhat.com List of files: /linux-6.15/drivers/gpu/drm/clients/Makefile
