25 Kernel-level support for the Direct Rendering Infrastructure (DRI)
26 introduced in XFree86 4.0. If you say Y here, you need to select
27 the module that's right for your graphics card from the list below.
28 These modules provide support for synchronization, security, and
29 DMA transfers. Please see <http://dri.sourceforge.net/> for more
30 details. You should also select and configure AGP
31 (/dev/agpgart) support if it is available for your platform.
43 bool "Insert extra checks and debug info into the DRM range managers"
46 depends on STACKTRACE_SUPPORT
49 Enable allocation tracking of memory manager and leak detection on
52 Recommended for driver developers only.
56 config DRM_USE_DYNAMIC_DEBUG
57 bool "use dynamic debug to implement drm.debug"
61 depends on DYNAMIC_DEBUG || DYNAMIC_DEBUG_CORE
64 Use dynamic-debug to avoid drm_debug_enabled() runtime overheads.
65 Due to callsite counts in DRM drivers (~4k in amdgpu) and 56
66 bytes per callsite, the .data costs can be substantial, and
67 are therefore configurable.

90 This builds unit tests for DRM. This option is not useful for
91 distributions or general kernels, but only for kernel
92 developers working on DRM and associated drivers.
94 For more information on KUnit and unit tests in general,
95 please refer to the KUnit documentation in
96 Documentation/dev-tools/kunit/.
100 config DRM_KMS_HELPER

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

122 bool "Enable backtrace history for lock contention"
123 depends on STACKTRACE_SUPPORT
124 depends on DEBUG_KERNEL
127 default y if DEBUG_WW_MUTEX_SLOWPATH
129 Enable debug tracing of failures to gracefully handle drm modeset lock
130 contention. A history of each drm modeset lock path hitting -EDEADLK
131 will be saved until gracefully handled, and the backtrace will be
132 printed when attempting to lock a contended lock.
134 If in doubt, say "N".
136 config DRM_FBDEV_EMULATION
137 bool "Enable legacy fbdev support for your modesetting driver"
139 select FRAMEBUFFER_CONSOLE_DETECT_PRIMARY if FRAMEBUFFER_CONSOLE
142 Choose this option if you have a need for the legacy fbdev
143 support. Note that this support also provides the linux console
144 support on top of your modesetting driver.
146 If in doubt, say "Y".
148 config DRM_FBDEV_OVERALLOC
149 int "Overallocation of the fbdev buffer"
150 depends on DRM_FBDEV_EMULATION
153 Defines the fbdev buffer overallocation in percent. Default
154 is 100. Typical values for double buffering will be 200,
155 triple buffering 300.
157 config DRM_FBDEV_LEAK_PHYS_SMEM
158 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
159 depends on DRM_FBDEV_EMULATION && EXPERT
162 In order to keep user-space compatibility, we want in certain
163 use-cases to keep leaking the fbdev physical address to the
164 user-space program handling the fbdev buffer.
165 This affects, not only, Amlogic, Allwinner or Rockchip devices
166 with ARM Mali GPUs using an userspace Blob.
167 This option is not supported by upstream developers and should be
168 removed as soon as possible and be considered as a broken and
169 legacy behaviour from a modern fbdev device driver.
171 Please send any bug reports when using this to your proprietary
172 software vendor that requires this.
174 If in doubt, say "N" or spread the word to your closed source
177 config DRM_LOAD_EDID_FIRMWARE
178 bool "Allow to specify an EDID data set instead of probing for it"
181 Say Y here, if you want to use EDID data to be loaded from the
182 /lib/firmware directory or one of the provided built-in
183 data sets. This may be necessary, if the graphics adapter or
184 monitor are unable to provide appropriate EDID data. Since this
185 feature is provided as a workaround for broken hardware, the
186 default case is N. Details and instructions how to build your own
187 EDID data are given in Documentation/admin-guide/edid.rst.
