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

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

76 This option provides kernel modules that can be used to run
77 various selftests on parts of the DRM api. This option is not
78 useful for distributions or general kernels, but only for kernel
79 developers working on DRM and associated drivers.

90 bool "Enable refcount backtrace history in the DP MST helpers"
91 depends on STACKTRACE_SUPPORT
93 depends on DRM_KMS_HELPER
94 depends on DEBUG_KERNEL
97 Enables debug tracing for topology refs in DRM's DP MST helpers. A
98 history of each topology reference/dereference will be printed to the
99 kernel log once a port or branch device's topology refcount reaches 0.
101 This has the potential to use a lot of memory and print some very
102 large kernel messages. If in doubt, say "N".

105 bool "Enable backtrace history for lock contention"
106 depends on STACKTRACE_SUPPORT
107 depends on DEBUG_KERNEL
110 default y if DEBUG_WW_MUTEX_SLOWPATH
112 Enable debug tracing of failures to gracefully handle drm modeset lock
113 contention. A history of each drm modeset lock path hitting -EDEADLK
114 will be saved until gracefully handled, and the backtrace will be
115 printed when attempting to lock a contended lock.

137 support on top of your modesetting driver.

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

412 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
413 APIs to user-space, which can be used to circumvent access
414 restrictions and other security measures. For backwards compatibility
415 those drivers are still available, but their use is highly
416 inadvisable and might harm your system.
418 You are recommended to use the safe modeset-only drivers instead, and
