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
53 bool "Insert extra checks and debug info into the DRM range managers"

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

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

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

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

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