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.

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

129 int "Overallocation of the fbdev buffer"

133 Defines the fbdev buffer overallocation in percent. Default
134 is 100. Typical values for double buffering will be 200,
135 triple buffering 300.

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

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