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.

42 Choose this option to enable a /dev/drm_dp_auxN node that allows to

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

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

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

386 depends on DRM && MMU
388 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
389 APIs to user-space, which can be used to circumvent access
390 restrictions and other security measures. For backwards compatibility
391 those drivers are still available, but their use is highly
392 inadvisable and might harm your system.
394 You are recommended to use the safe modeset-only drivers instead, and
395 perform 3D emulation in user-space.
397 Unless you have strong reasons to go rogue, say "N".
