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.

54 bool "use dynamic debug to implement drm.debug"
57 depends on DYNAMIC_DEBUG || DYNAMIC_DEBUG_CORE
60 Use dynamic-debug to avoid drm_debug_enabled() runtime overheads.
61 Due to callsite counts in DRM drivers (~4k in amdgpu) and 56
62 bytes per callsite, the .data costs can be substantial, and
63 are therefore configurable.

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.

109 depends on STACKTRACE_SUPPORT
111 depends on DRM_KMS_HELPER
112 depends on DEBUG_KERNEL
115 Enables debug tracing for topology refs in DRM's DP MST helpers. A
116 history of each topology reference/dereference will be printed to the
117 kernel log once a port or branch device's topology refcount reaches 0.
119 This has the potential to use a lot of memory and print some very
120 large kernel messages. If in doubt, say "N".

130 Enable debug tracing of failures to gracefully handle drm modeset lock
131 contention. A history of each drm modeset lock path hitting -EDEADLK
132 will be saved until gracefully handled, and the backtrace will be
133 printed when attempting to lock a contended lock.

161 depends on DRM_FBDEV_EMULATION
164 Defines the fbdev buffer overallocation in percent. Default
165 is 100. Typical values for double buffering will be 200,
166 triple buffering 300.
168 config DRM_FBDEV_LEAK_PHYS_SMEM
169 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
170 depends on DRM_FBDEV_EMULATION && EXPERT
173 In order to keep user-space compatibility, we want in certain
174 use-cases to keep leaking the fbdev physical address to the
175 user-space program handling the fbdev buffer.
176 This affects, not only, Amlogic, Allwinner or Rockchip devices
177 with ARM Mali GPUs using an userspace Blob.
178 This option is not supported by upstream developers and should be
179 removed as soon as possible and be considered as a broken and
180 legacy behaviour from a modern fbdev device driver.
182 Please send any bug reports when using this to your proprietary
183 software vendor that requires this.
185 If in doubt, say "N" or spread the word to your closed source
188 config DRM_LOAD_EDID_FIRMWARE
189 bool "Allow to specify an EDID data set instead of probing for it"
192 Say Y here, if you want to use EDID data to be loaded from the
193 /lib/firmware directory or one of the provided built-in
194 data sets. This may be necessary, if the graphics adapter or
195 monitor are unable to provide appropriate EDID data. Since this
196 feature is provided as a workaround for broken hardware, the
197 default case is N. Details and instructions how to build your own
198 EDID data are given in Documentation/admin-guide/edid.rst.

438 APIs to user-space, which can be used to circumvent access
439 restrictions and other security measures. For backwards compatibility
440 those drivers are still available, but their use is highly
441 inadvisable and might harm your system.
