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 for more details. You should also select and configure AGP (/dev/agpgart) support if it is available for your platform. config DRM_MIPI_DSI bool depends on DRM config DRM_DP_AUX_CHARDEV bool "DRM DP AUX Interface" depends on DRM help Choose this option to enable a /dev/drm_dp_auxN node that allows to read and write values to arbitrary DPCD registers on the DP aux channel. config DRM_DEBUG_MM bool "Insert extra checks and debug info into the DRM range managers" default n depends on DRM=y depends on STACKTRACE_SUPPORT select STACKDEPOT help Enable allocation tracking of memory manager and leak detection on shutdown. Recommended for driver developers only. If in doubt, say "N". config DRM_DEBUG_SELFTEST tristate "kselftests for DRM" depends on DRM depends on DEBUG_KERNEL select PRIME_NUMBERS select DRM_LIB_RANDOM select DRM_KMS_HELPER default n help This option provides kernel modules that can be used to run various selftests on parts of the DRM api. This option is not useful for distributions or general kernels, but only for kernel developers working on DRM and associated drivers. If in doubt, say "N". config DRM_KMS_HELPER tristate depends on DRM help CRTC helpers for KMS drivers. config DRM_KMS_FB_HELPER bool depends on DRM_KMS_HELPER select FB select FRAMEBUFFER_CONSOLE if !EXPERT select FRAMEBUFFER_CONSOLE_DETECT_PRIMARY if FRAMEBUFFER_CONSOLE select FB_SYS_FOPS select FB_SYS_FILLRECT select FB_SYS_COPYAREA select FB_SYS_IMAGEBLIT select FB_CFB_FILLRECT select FB_CFB_COPYAREA select FB_CFB_IMAGEBLIT select FB_DEFERRED_IO help FBDEV helpers for KMS drivers. config DRM_FBDEV_EMULATION bool "Enable legacy fbdev support for your modesetting driver" depends on DRM select DRM_KMS_HELPER select DRM_KMS_FB_HELPER default y help Choose this option if you have a need for the legacy fbdev support. Note that this support also provides the linux console support on top of your modesetting driver. If in doubt, say "Y". config DRM_FBDEV_OVERALLOC int "Overallocation of the fbdev buffer" depends on DRM_FBDEV_EMULATION default 100 help Defines the fbdev buffer overallocation in percent. Default is 100. Typical values for double buffering will be 200, triple buffering 300. config DRM_FBDEV_LEAK_PHYS_SMEM bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)" depends on DRM_FBDEV_EMULATION && EXPERT default n help In order to keep user-space compatibility, we want in certain use-cases to keep leaking the fbdev physical address to the user-space program handling the fbdev buffer. This affects, not only, Amlogic, Allwinner or Rockchip devices with ARM Mali GPUs using an userspace Blob. This option is not supported by upstream developers and should be removed as soon as possible and be considered as a broken and legacy behaviour from a modern fbdev device driver. Please send any bug reports when using this to your proprietary software vendor that requires this. If in doubt, say "N" or spread the word to your closed source library vendor. 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/EDID/HOWTO.txt. config DRM_DP_CEC bool "Enable DisplayPort CEC-Tunneling-over-AUX HDMI support" select CEC_CORE help Choose this option if you want to enable HDMI CEC support for DisplayPort/USB-C to HDMI adapters. Note: not all adapters support this feature, and even for those that do support this they often do not hook up the CEC pin. config DRM_TTM tristate depends on DRM && MMU help GPU memory management subsystem for devices with multiple GPU memory types.

Those drivers expose unsafe and dangerous APIs to user-space, which can be used to circumvent access restrictions and other security measures. For backwards compatibility those drivers are still available, but their use is highly inadvisable and might harm your system. You are recommended to use the safe modeset-only drivers instead, and perform 3D emulation in user-space. Unless you have strong reasons to go rogue, say "N". if DRM_LEGACY config DRM_TDFX tristate "3dfx Banshee/Voodoo3+" depends on DRM && PCI help Choose this option if you have a 3dfx Banshee or Voodoo3 (or later), graphics card.
