If you say Y here, you need to select the module that's right for your graphics card from the list below. These modules provide support for synchronization, security, and DMA transfers. Please see <http://dri.sourceforge.net/> for more details. You should also select and configure AGP (/dev/agpgart) support if it is available for your platform.

config DRM_MIPI_DBI tristate depends on DRM select DRM_KMS_HELPER
config DRM_MIPI_DSI bool depends on DRM
config DRM_KMS_HELPER tristate depends on DRM select FB_CORE if DRM_FBDEV_EMULATION help CRTC helpers for KMS drivers.
config DRM_DRAW bool depends on DRM
config DRM_PANIC bool "Display a user-friendly message when a kernel panic occurs" depends on DRM && PRINTK select FONT_SUPPORT select DRM_DRAW help 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
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. If in doubt, say "N".
config DRM_DEBUG_DP_MST_TOPOLOGY_REFS bool "Enable refcount backtrace history in the DP MST helpers" depends on STACKTRACE_SUPPORT select STACKDEPOT select DRM_KMS_HELPER depends on DEBUG_KERNEL depends on EXPERT help 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 depends on DEBUG_KERNEL depends on EXPERT select STACKDEPOT default y if DEBUG_WW_MUTEX_SLOWPATH help 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.

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