22 Kernel-level support for the Direct Rendering Infrastructure (DRI)
23 introduced in XFree86 4.0. If you say Y here, you need to select
24 the module that's right for your graphics card from the list below.
25 These modules provide support for synchronization, security, and
26 DMA transfers. Please see <http://dri.sourceforge.net/> for more
27 details. You should also select and configure AGP
28 (/dev/agpgart) support if it is available for your platform.

44 bool "DRM DP AUX Interface"
47 Choose this option to enable a /dev/drm_dp_auxN node that allows to
48 read and write values to arbitrary DPCD registers on the DP aux

72 select DRM_EXPORT_FOR_TESTS if m
75 This option provides kernel modules that can be used to run
76 various selftests on parts of the DRM api. This option is not
77 useful for distributions or general kernels, but only for kernel
78 developers working on DRM and associated drivers.
86 CRTC helpers for KMS drivers.

89 bool "Enable refcount backtrace history in the DP MST helpers"
90 depends on STACKTRACE_SUPPORT
92 depends on DRM_KMS_HELPER
93 depends on DEBUG_KERNEL
96 Enables debug tracing for topology refs in DRM's DP MST helpers. A
97 history of each topology reference/dereference will be printed to the
98 kernel log once a port or branch device's topology refcount reaches 0.
100 This has the potential to use a lot of memory and print some very

127 int "Overallocation of the fbdev buffer"
128 depends on DRM_FBDEV_EMULATION
131 Defines the fbdev buffer overallocation in percent. Default
132 is 100. Typical values for double buffering will be 200,
133 triple buffering 300.
135 config DRM_FBDEV_LEAK_PHYS_SMEM
136 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
137 depends on DRM_FBDEV_EMULATION && EXPERT
140 In order to keep user-space compatibility, we want in certain
141 use-cases to keep leaking the fbdev physical address to the
142 user-space program handling the fbdev buffer.
143 This affects, not only, Amlogic, Allwinner or Rockchip devices
144 with ARM Mali GPUs using an userspace Blob.
145 This option is not supported by upstream developers and should be
146 removed as soon as possible and be considered as a broken and
147 legacy behaviour from a modern fbdev device driver.
149 Please send any bug reports when using this to your proprietary
150 software vendor that requires this.
152 If in doubt, say "N" or spread the word to your closed source
155 config DRM_LOAD_EDID_FIRMWARE
156 bool "Allow to specify an EDID data set instead of probing for it"
159 Say Y here, if you want to use EDID data to be loaded from the
160 /lib/firmware directory or one of the provided built-in
161 data sets. This may be necessary, if the graphics adapter or
162 monitor are unable to provide appropriate EDID data. Since this
163 feature is provided as a workaround for broken hardware, the
164 default case is N. Details and instructions how to build your own
165 EDID data are given in Documentation/admin-guide/edid.rst.
168 bool "Enable DisplayPort CEC-Tunneling-over-AUX HDMI support"
172 Choose this option if you want to enable HDMI CEC support for
173 DisplayPort/USB-C to HDMI adapters.
175 Note: not all adapters support this feature, and even for those
176 that do support this they often do not hook up the CEC pin.

401 depends on DRM && MMU
403 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
404 APIs to user-space, which can be used to circumvent access
405 restrictions and other security measures. For backwards compatibility
406 those drivers are still available, but their use is highly
407 inadvisable and might harm your system.
409 You are recommended to use the safe modeset-only drivers instead, and
