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.

54 bool "use dynamic debug to implement drm.debug"
58 depends on DYNAMIC_DEBUG || DYNAMIC_DEBUG_CORE
61 Use dynamic-debug to avoid drm_debug_enabled() runtime overheads.
62 Due to callsite counts in DRM drivers (~4k in amdgpu) and 56
63 bytes per callsite, the .data costs can be substantial, and
64 are therefore configurable.

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

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

156 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
157 depends on DRM_FBDEV_EMULATION && EXPERT
160 In order to keep user-space compatibility, we want in certain
161 use-cases to keep leaking the fbdev physical address to the
162 user-space program handling the fbdev buffer.
163 This affects, not only, Amlogic, Allwinner or Rockchip devices
164 with ARM Mali GPUs using an userspace Blob.
165 This option is not supported by upstream developers and should be
166 removed as soon as possible and be considered as a broken and
167 legacy behaviour from a modern fbdev device driver.
169 Please send any bug reports when using this to your proprietary
170 software vendor that requires this.
172 If in doubt, say "N" or spread the word to your closed source
175 config DRM_LOAD_EDID_FIRMWARE
176 bool "Allow to specify an EDID data set instead of probing for it"
179 Say Y here, if you want to use EDID data to be loaded from the
180 /lib/firmware directory or one of the provided built-in
181 data sets. This may be necessary, if the graphics adapter or
182 monitor are unable to provide appropriate EDID data. Since this
183 feature is provided as a workaround for broken hardware, the
184 default case is N. Details and instructions how to build your own
185 EDID data are given in Documentation/admin-guide/edid.rst.

387 restrictions and other security measures. For backwards compatibility
388 those drivers are still available, but their use is highly
389 inadvisable and might harm your system.
