Thomas Zimmermann 0a8bc1d03e drm/client: log: Implement struct drm_client_funcs.restore ... Restore the log client's output when the DRM core invokes the restore callback. Follow the existing behavior of fbdev emulation wrt. the value of the force parameter. If force is false, acquire the DRM master lock and reprogram the display. This is the case when the user-space compositor exits and the DRM core transfers the display back to the in-kernel client. This also enables drm_log output during reboot and shutdown. If force is true, reprogram without considering the master lock. This overrides the current compositor and prints the log to the screen. In case of system malfunction, users can enter SysRq+v to invoke the emergency error reporting. See Documentation/admin-guide/sysrq.rst for more information. v2: - s/exists/exits/ in second paragraph of commit description - fix grammar in commit description Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Link: https://patch.msgid.link/20251110154616.539328-4-tzimmermann@suse.de		2025-11-25 08:43:48 +01:00
