	DRM's fbdev helpers are for the fbdev-emulation clients. Move them into the client-library module. Fix include statements throughout DRM drivers. While at it, rename the files from drm_fb_helper to drm_fbdev_helper. The old name was too reminiscent of DRM's framebuffer code. The GEM support code for fbdev remains part of DRM's memory managers. v4: - fix the depedendencies from v3 v3: - remove obsolete dependencies from Kconfig v2: - update armada und docs Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Acked-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patch.msgid.link/20260928080323.23909-3-tzimmermann@suse.de
2024-12-10	drm/log: Introduce a new boot logger to draw the kmsg on the screen	Jocelyn Falempe
	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 <jfalempe@redhat.com> Reviewed-by: John Ogness <john.ogness@linutronix.de> # console API Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20241204160014.1171469-3-jfalempe@redhat.com
