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.

67 various selftests on parts of the DRM api. This option is not
68 useful for distributions or general kernels, but only for kernel
69 developers working on DRM and associated drivers.

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

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

131 config DRM_FBDEV_OVERALLOC
132 int "Overallocation of the fbdev buffer"
133 depends on DRM_FBDEV_EMULATION
136 Defines the fbdev buffer overallocation in percent. Default
137 is 100. Typical values for double buffering will be 200,
138 triple buffering 300.
140 config DRM_FBDEV_LEAK_PHYS_SMEM
141 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
142 depends on DRM_FBDEV_EMULATION && EXPERT
145 In order to keep user-space compatibility, we want in certain
146 use-cases to keep leaking the fbdev physical address to the
147 user-space program handling the fbdev buffer.
148 This affects, not only, Amlogic, Allwinner or Rockchip devices
149 with ARM Mali GPUs using an userspace Blob.
150 This option is not supported by upstream developers and should be
151 removed as soon as possible and be considered as a broken and
152 legacy behaviour from a modern fbdev device driver.
154 Please send any bug reports when using this to your proprietary
155 software vendor that requires this.
157 If in doubt, say "N" or spread the word to your closed source
160 config DRM_LOAD_EDID_FIRMWARE
161 bool "Allow to specify an EDID data set instead of probing for it"
164 Say Y here, if you want to use EDID data to be loaded from the
165 /lib/firmware directory or one of the provided built-in
166 data sets. This may be necessary, if the graphics adapter or
167 monitor are unable to provide appropriate EDID data. Since this
168 feature is provided as a workaround for broken hardware, the
169 default case is N. Details and instructions how to build your own
170 EDID data are given in Documentation/admin-guide/edid.rst.

407 APIs to user-space, which can be used to circumvent access
408 restrictions and other security measures. For backwards compatibility
409 those drivers are still available, but their use is highly
410 inadvisable and might harm your system.
412 You are recommended to use the safe modeset-only drivers instead, and
413 perform 3D emulation in user-space.
