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 distributions or general kernels, but only for kernel
91 developers working on DRM and associated drivers.

94 please refer to the KUnit documentation in

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

126 default y if DEBUG_WW_MUTEX_SLOWPATH
128 Enable debug tracing of failures to gracefully handle drm modeset lock
129 contention. A history of each drm modeset lock path hitting -EDEADLK
130 will be saved until gracefully handled, and the backtrace will be
131 printed when attempting to lock a contended lock.
133 If in doubt, say "N".
135 config DRM_FBDEV_EMULATION
136 bool "Enable legacy fbdev support for your modesetting driver"

142 support. Note that this support also provides the linux console
143 support on top of your modesetting driver.
145 If in doubt, say "Y".
147 config DRM_FBDEV_OVERALLOC
148 int "Overallocation of the fbdev buffer"
149 depends on DRM_FBDEV_EMULATION
152 Defines the fbdev buffer overallocation in percent. Default
153 is 100. Typical values for double buffering will be 200,
154 triple buffering 300.
156 config DRM_FBDEV_LEAK_PHYS_SMEM
157 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
158 depends on DRM_FBDEV_EMULATION && EXPERT
161 In order to keep user-space compatibility, we want in certain
162 use-cases to keep leaking the fbdev physical address to the
163 user-space program handling the fbdev buffer.
164 This affects, not only, Amlogic, Allwinner or Rockchip devices
165 with ARM Mali GPUs using an userspace Blob.
166 This option is not supported by upstream developers and should be
167 removed as soon as possible and be considered as a broken and
168 legacy behaviour from a modern fbdev device driver.
170 Please send any bug reports when using this to your proprietary
171 software vendor that requires this.
173 If in doubt, say "N" or spread the word to your closed source
176 config DRM_LOAD_EDID_FIRMWARE
177 bool "Allow to specify an EDID data set instead of probing for it"
180 Say Y here, if you want to use EDID data to be loaded from the
181 /lib/firmware directory or one of the provided built-in
182 data sets. This may be necessary, if the graphics adapter or
183 monitor are unable to provide appropriate EDID data. Since this
184 feature is provided as a workaround for broken hardware, the
185 default case is N. Details and instructions how to build your own
186 EDID data are given in Documentation/admin-guide/edid.rst.

409 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
410 APIs to user-space, which can be used to circumvent access
411 restrictions and other security measures. For backwards compatibility
412 those drivers are still available, but their use is highly
413 inadvisable and might harm your system.
415 You are recommended to use the safe modeset-only drivers instead, and
416 perform 3D emulation in user-space.
