25 These modules provide support for synchronization, security, and

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.

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

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

167 In order to keep user-space compatibility, we want in certain
168 use-cases to keep leaking the fbdev physical address to the
169 user-space program handling the fbdev buffer.
170 This affects, not only, Amlogic, Allwinner or Rockchip devices
171 with ARM Mali GPUs using an userspace Blob.
172 This option is not supported by upstream developers and should be
173 removed as soon as possible and be considered as a broken and
174 legacy behaviour from a modern fbdev device driver.
176 Please send any bug reports when using this to your proprietary
177 software vendor that requires this.
179 If in doubt, say "N" or spread the word to your closed source

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

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