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

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

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

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

209 Enables unit tests for TTM, a GPU memory manager subsystem used
210 to manage memory buffers. This option is mostly useful for kernel
211 developers. It depends on (UML || COMPILE_TEST) since no other driver
212 which uses TTM can be loaded while running the tests.

423 bool "Compile the drm subsystem with warnings as errors"
424 depends on DRM && EXPERT
427 A kernel build should not cause any compiler warnings, and this
428 enables the '-Werror' flag to enforce that rule in the drm subsystem.
430 The drm subsystem enables more warnings than the kernel default, so
431 this config option is disabled by default.
