It's useful when using a user-space	  console instead of fbcon.	  It will only work if your graphic driver supports this feature.	  To support Hi-DPI Display, you can enable bigger fonts like	  FONT_TER16x32 config DRM_PANIC_FOREGROUND_COLOR	hex "Drm panic screen foreground color, in RGB"	depends on DRM_PANIC	default 0xffffff config DRM_PANIC_BACKGROUND_COLOR	hex "Drm panic screen background color, in RGB"	depends on DRM_PANIC	default 0x000000 config DRM_PANIC_DEBUG	bool "Add a debug fs entry to trigger drm_panic"	depends on DRM_PANIC && DEBUG_FS	help	  Add dri/[device]/drm_panic_plane_x in the kernel debugfs, to force the	  panic handler to write the panic message to this plane scanout buffer.	  This is unsafe and should not be enabled on a production build.	  If in doubt, say "N". config DRM_PANIC_SCREEN	string "Panic screen formatter"	default "user"	depends on DRM_PANIC	help	  This option enable to choose what will be displayed when a kernel	  panic occurs. You can choose between "user", a short message telling	  the user to reboot the system, or "kmsg" which will display the last	  lines of kmsg.	  This can also be overridden by drm.panic_screen=xxxx kernel parameter	  or by writing to /sys/module/drm/parameters/panic_screen sysfs entry	  Default is "user" config DRM_PANIC_SCREEN_QR_CODE	bool "Add a panic screen with a QR code"	depends on DRM_PANIC && RUST	select ZLIB_DEFLATE	help	  This option adds a QR code generator, and a panic screen with a QR	  code. The QR code will contain the last lines of kmsg and other debug	  information. This should be easier for the user to report a kernel	  panic, with all debug information available.	  To use this panic screen, also set DRM_PANIC_SCREEN to "qr_code" config DRM_PANIC_SCREEN_QR_CODE_URL	string "Base URL of the QR code in the panic screen"	depends on DRM_PANIC_SCREEN_QR_CODE	help	  This option sets the base URL to report the kernel panic. If it's set	  the QR code will contain the URL and the kmsg compressed with zlib as	  a URL parameter. If it's empty, the QR code will contain the kmsg as	  uncompressed text only.	  There is a demo code in javascript, to decode and uncompress the kmsg	  data from the URL parameter at https://github.com/kdj0c/panic_report config DRM_PANIC_SCREEN_QR_VERSION	int "Maximum version (size) of the QR code."	depends on DRM_PANIC_SCREEN_QR_CODE	default 40	help	  This option limits the version (or size) of the QR code. QR code	  version ranges from Version 1 (21x21) to Version 40 (177x177).	  Smaller QR code are easier to read, but will contain less debugging	  data. Default is 40. config DRM_RAS	bool "DRM RAS support"	depends on DRM	depends on NET	help	  Enables the DRM RAS (Reliability, Availability and Serviceability)	  support for DRM drivers. This provides a Generic Netlink interface	  for error reporting and queries.

A          history of each topology reference/dereference will be printed to the          kernel log once a port or branch device's topology refcount reaches 0.           This has the potential to use a lot of memory and print some very          large kernel messages.

A history of each drm modeset lock path hitting -EDEADLK	  will be saved until gracefully handled, and the backtrace will be	  printed when attempting to lock a contended lock. 	  If in doubt, say "N". config DRM_CLIENT	bool	depends on DRM	help	  Enables support for DRM clients. DRM drivers that need	  struct drm_client_dev and its interfaces should select this	  option. Drivers that support the default clients should	  select DRM_CLIENT_SELECTION instead. source "drivers/gpu/drm/clients/Kconfig" config DRM_LOAD_EDID_FIRMWARE	bool "Allow to specify an EDID data set instead of probing for it"	depends on DRM	help	  Say Y here, if you want to use EDID data to be loaded from the	  /lib/firmware directory or one of the provided built-in	  data sets. This may be necessary, if the graphics adapter or	  monitor are unable to provide appropriate EDID data. Since this	  feature is provided as a workaround for broken hardware, the	  default case is N.
