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.
44 bool "Insert extra checks and debug info into the DRM range managers"
47 depends on STACKTRACE_SUPPORT
50 Enable allocation tracking of memory manager and leak detection on
53 Recommended for driver developers only.
57 config DRM_USE_DYNAMIC_DEBUG
58 bool "use dynamic debug to implement drm.debug"
62 depends on DYNAMIC_DEBUG || DYNAMIC_DEBUG_CORE
65 Use dynamic-debug to avoid drm_debug_enabled() runtime overheads.
66 Due to callsite counts in DRM drivers (~4k in amdgpu) and 56
67 bytes per callsite, the .data costs can be substantial, and
68 are therefore configurable.

89 default KUNIT_ALL_TESTS
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 "Display a user-friendly message when a kernel panic occurs"
109 depends on DRM && !FRAMEBUFFER_CONSOLE
110 select DRM_KMS_HELPER
113 Enable a drm panic handler, which will display a user-friendly message
114 when a kernel panic occurs. It's useful when using a user-space
115 console instead of fbcon.
116 It will only work if your graphic driver supports this feature.
117 To support Hi-DPI Display, you can enable bigger fonts like
120 config DRM_PANIC_FOREGROUND_COLOR
121 hex "Drm panic screen foreground color, in RGB"
125 config DRM_PANIC_BACKGROUND_COLOR
126 hex "Drm panic screen background color, in RGB"
130 config DRM_PANIC_DEBUG
131 bool "Add a debug fs entry to trigger drm_panic"
132 depends on DRM_PANIC && DEBUG_FS
134 Add dri/[device]/drm_panic_plane_x in the kernel debugfs, to force the
135 panic handler to write the panic message to this plane scanout buffer.
136 This is unsafe and should not be enabled on a production build.
137 If in doubt, say "N".
139 config DRM_DEBUG_DP_MST_TOPOLOGY_REFS
140 bool "Enable refcount backtrace history in the DP MST helpers"
141 depends on STACKTRACE_SUPPORT
143 depends on DRM_KMS_HELPER
144 depends on DEBUG_KERNEL
147 Enables debug tracing for topology refs in DRM's DP MST helpers. A
148 history of each topology reference/dereference will be printed to the
149 kernel log once a port or branch device's topology refcount reaches 0.
151 This has the potential to use a lot of memory and print some very
152 large kernel messages. If in doubt, say "N".
154 config DRM_DEBUG_MODESET_LOCK
155 bool "Enable backtrace history for lock contention"
156 depends on STACKTRACE_SUPPORT
157 depends on DEBUG_KERNEL
160 default y if DEBUG_WW_MUTEX_SLOWPATH
162 Enable debug tracing of failures to gracefully handle drm modeset lock
163 contention. A history of each drm modeset lock path hitting -EDEADLK
164 will be saved until gracefully handled, and the backtrace will be
165 printed when attempting to lock a contended lock.
167 If in doubt, say "N".
169 config DRM_FBDEV_EMULATION
170 bool "Enable legacy fbdev support for your modesetting driver"
172 select FRAMEBUFFER_CONSOLE_DETECT_PRIMARY if FRAMEBUFFER_CONSOLE
175 Choose this option if you have a need for the legacy fbdev
176 support. Note that this support also provides the linux console
177 support on top of your modesetting driver.
179 If in doubt, say "Y".
181 config DRM_FBDEV_OVERALLOC
182 int "Overallocation of the fbdev buffer"
183 depends on DRM_FBDEV_EMULATION
186 Defines the fbdev buffer overallocation in percent. Default
187 is 100. Typical values for double buffering will be 200,
188 triple buffering 300.
190 config DRM_FBDEV_LEAK_PHYS_SMEM
191 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
192 depends on DRM_FBDEV_EMULATION && EXPERT
195 In order to keep user-space compatibility, we want in certain
196 use-cases to keep leaking the fbdev physical address to the
197 user-space program handling the fbdev buffer.
198 This affects, not only, Amlogic, Allwinner or Rockchip devices
199 with ARM Mali GPUs using an userspace Blob.
200 This option is not supported by upstream developers and should be
201 removed as soon as possible and be considered as a broken and
202 legacy behaviour from a modern fbdev device driver.
204 Please send any bug reports when using this to your proprietary
205 software vendor that requires this.
207 If in doubt, say "N" or spread the word to your closed source
210 config DRM_LOAD_EDID_FIRMWARE
211 bool "Allow to specify an EDID data set instead of probing for it"
214 Say Y here, if you want to use EDID data to be loaded from the
215 /lib/firmware directory or one of the provided built-in
216 data sets. This may be necessary, if the graphics adapter or
217 monitor are unable to provide appropriate EDID data. Since this
218 feature is provided as a workaround for broken hardware, the
219 default case is N. Details and instructions how to build your own
220 EDID data are given in Documentation/admin-guide/edid.rst.

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

451 bool "Compile the drm subsystem with warnings as errors"
452 depends on DRM && EXPERT
455 A kernel build should not cause any compiler warnings, and this
456 enables the '-Werror' flag to enforce that rule in the drm subsystem.
458 The drm subsystem enables more warnings than the kernel default, so
459 this config option is disabled by default.
