	  Enable a drm panic handler, which will display a user-friendly message
	  when a kernel panic occurs. 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

	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

	  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.

          Enables debug tracing for topology refs in DRM's DP MST helpers. 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. If in doubt, say "N".

config DRM_DEBUG_MODESET_LOCK
	bool "Enable backtrace history for lock contention"
	depends on STACKTRACE_SUPPORT

	  Enable debug tracing of failures to gracefully handle drm modeset lock
	  contention. 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.

	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. Details and instructions how to build your own
	  EDID data are given in Documentation/admin-guide/edid.rst.
