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.

43 Choose this option to enable a /dev/drm_dp_auxN node that allows to
44 read and write values to arbitrary DPCD registers on the DP aux

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

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

124 support. Note that this support also provides the linux console
125 support on top of your modesetting driver.

129 config DRM_FBDEV_OVERALLOC
130 int "Overallocation of the fbdev buffer"
131 depends on DRM_FBDEV_EMULATION
134 Defines the fbdev buffer overallocation in percent. Default
135 is 100. Typical values for double buffering will be 200,
136 triple buffering 300.

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

400 depends on DRM && MMU
403 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
404 APIs to user-space, which can be used to circumvent access
405 restrictions and other security measures. For backwards compatibility
406 those drivers are still available, but their use is highly
407 inadvisable and might harm your system.
409 You are recommended to use the safe modeset-only drivers instead, and
410 perform 3D emulation in user-space.
412 Unless you have strong reasons to go rogue, say "N".

439 for this driver to work.
