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.

103 Enables debug tracing for topology refs in DRM's DP MST helpers. A
104 history of each topology reference/dereference will be printed to the
105 kernel log once a port or branch device's topology refcount reaches 0.
107 This has the potential to use a lot of memory and print some very

119 contention. A history of each drm modeset lock path hitting -EDEADLK
120 will be saved until gracefully handled, and the backtrace will be
121 printed when attempting to lock a contended lock.

157 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
158 depends on DRM_FBDEV_EMULATION && EXPERT
161 In order to keep user-space compatibility, we want in certain
162 use-cases to keep leaking the fbdev physical address to the
163 user-space program handling the fbdev buffer.
164 This affects, not only, Amlogic, Allwinner or Rockchip devices
165 with ARM Mali GPUs using an userspace Blob.
166 This option is not supported by upstream developers and should be
167 removed as soon as possible and be considered as a broken and
168 legacy behaviour from a modern fbdev device driver.
170 Please send any bug reports when using this to your proprietary
171 software vendor that requires this.
173 If in doubt, say "N" or spread the word to your closed source

180 Say Y here, if you want to use EDID data to be loaded from the
181 /lib/firmware directory or one of the provided built-in
182 data sets. This may be necessary, if the graphics adapter or
183 monitor are unable to provide appropriate EDID data. Since this
184 feature is provided as a workaround for broken hardware, the
185 default case is N. Details and instructions how to build your own
186 EDID data are given in Documentation/admin-guide/edid.rst.

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