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_DBI tristate depends on DRM select DRM_KMS_HELPER config DRM_MIPI_DSI bool depends on DRM 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.

Due to callsite counts in DRM drivers (~4k in amdgpu) and 56 bytes per callsite, the .data costs can be substantial, and are therefore configurable. config DRM_KUNIT_TEST_HELPERS tristate depends on DRM && KUNIT help KUnit Helpers for KMS drivers. config DRM_KUNIT_TEST tristate "KUnit tests for DRM" if !KUNIT_ALL_TESTS depends on DRM && KUNIT select PRIME_NUMBERS select DRM_DISPLAY_DP_HELPER select DRM_DISPLAY_HELPER select DRM_LIB_RANDOM select DRM_KMS_HELPER select DRM_BUDDY select DRM_EXPORT_FOR_TESTS if m select DRM_KUNIT_TEST_HELPERS default KUNIT_ALL_TESTS help This builds unit tests for DRM.

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.

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.

If M is selected the module will be called hyperv_drm. # Keep legacy drivers last menuconfig DRM_LEGACY bool "Enable legacy drivers (DANGEROUS)" depends on DRM && MMU help Enable legacy DRI1 drivers. 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.
