drm/log: select CONFIG_FONT_SUPPORT

2024-12-12T17:26:32+00:00

Without fonts, this fails to link: drivers/gpu/drm/clients/drm_log.o: in function `drm_log_init_client': drm_log.c:(.text+0x3d4): undefined reference to `get_default_font' Select this, like the other users do.

drm/client: Fix drm client endless Kconfig loop

2024-12-12T10:22:32+00:00

if DRM_CLIENT_SELECTION is enabled, and none of the client is, the "Default DRM Client" choice is empty, and this makes Kconfig goes into an infinite loop of: Default DRM Client choice[1-0?]: 0 Default DRM Client choice[1-0?]: 0 Default DRM Client choice[1-0?]: 0 .... So only allow the choice if at least one of the client is selected.

drm/log: Introduce a new boot logger to draw the kmsg on the screen

2024-12-10T13:36:53+00:00

drm_log is a simple logger that uses the drm_client API to print the kmsg 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 a terminal 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=fbdev Signed-off-by: Jocelyn Falempe Reviewed-by: John Ogness # console API Reviewed-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20241204160014.1171469-3-jfalempe@redhat.com

drm: Move client code to clients/ subdirectory

2024-11-15T08:42:11+00:00

Just move some files around to keep source code well organized. Plus fix a type in the help text of CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM. No functional changes.
