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

90 distributions or general kernels, but only for kernel
91 developers working on DRM and associated drivers.
93 For more information on KUnit and unit tests in general,
94 please refer to the KUnit documentation in

111 bool "Display a user-friendly message when a kernel panic occurs"
116 Enable a drm panic handler, which will display a user-friendly message
117 when a kernel panic occurs. It's useful when using a user-space
118 console instead of fbcon.
119 It will only work if your graphic driver supports this feature.
120 To support Hi-DPI Display, you can enable bigger fonts like
123 config DRM_PANIC_FOREGROUND_COLOR
124 hex "Drm panic screen foreground color, in RGB"
128 config DRM_PANIC_BACKGROUND_COLOR
129 hex "Drm panic screen background color, in RGB"
133 config DRM_PANIC_DEBUG
134 bool "Add a debug fs entry to trigger drm_panic"
135 depends on DRM_PANIC && DEBUG_FS
137 Add dri/[device]/drm_panic_plane_x in the kernel debugfs, to force the
138 panic handler to write the panic message to this plane scanout buffer.
139 This is unsafe and should not be enabled on a production build.
140 If in doubt, say "N".
142 config DRM_PANIC_SCREEN
143 string "Panic screen formatter"
147 This option enable to choose what will be displayed when a kernel
148 panic occurs. You can choose between "user", a short message telling
149 the user to reboot the system, or "kmsg" which will display the last
151 This can also be overridden by drm.panic_screen=xxxx kernel parameter
152 or by writing to /sys/module/drm/parameters/panic_screen sysfs entry
155 config DRM_PANIC_SCREEN_QR_CODE
156 bool "Add a panic screen with a QR code"
157 depends on DRM_PANIC && RUST
160 This option adds a QR code generator, and a panic screen with a QR
161 code. The QR code will contain the last lines of kmsg and other debug
162 information. This should be easier for the user to report a kernel
163 panic, with all debug information available.
164 To use this panic screen, also set DRM_PANIC_SCREEN to "qr_code"
166 config DRM_PANIC_SCREEN_QR_CODE_URL
167 string "Base URL of the QR code in the panic screen"
168 depends on DRM_PANIC_SCREEN_QR_CODE
170 This option sets the base URL to report the kernel panic. If it's set
171 the QR code will contain the URL and the kmsg compressed with zlib as
172 a URL parameter. If it's empty, the QR code will contain the kmsg as
173 uncompressed text only.
174 There is a demo code in javascript, to decode and uncompress the kmsg
175 data from the URL parameter at https://github.com/kdj0c/panic_report
177 config DRM_PANIC_SCREEN_QR_VERSION
178 int "Maximum version (size) of the QR code."
179 depends on DRM_PANIC_SCREEN_QR_CODE
182 This option limits the version (or size) of the QR code. QR code
183 version ranges from Version 1 (21x21) to Version 40 (177x177).
184 Smaller QR code are easier to read, but will contain less debugging
187 config DRM_DEBUG_DP_MST_TOPOLOGY_REFS
188 bool "Enable refcount backtrace history in the DP MST helpers"
189 depends on STACKTRACE_SUPPORT
191 depends on DRM_KMS_HELPER
192 depends on DEBUG_KERNEL
195 Enables debug tracing for topology refs in DRM's DP MST helpers. A
196 history of each topology reference/dereference will be printed to the
197 kernel log once a port or branch device's topology refcount reaches 0.
199 This has the potential to use a lot of memory and print some very
200 large kernel messages. If in doubt, say "N".
202 config DRM_DEBUG_MODESET_LOCK
203 bool "Enable backtrace history for lock contention"
204 depends on STACKTRACE_SUPPORT
205 depends on DEBUG_KERNEL
208 default y if DEBUG_WW_MUTEX_SLOWPATH
210 Enable debug tracing of failures to gracefully handle drm modeset lock
211 contention. A history of each drm modeset lock path hitting -EDEADLK
212 will be saved until gracefully handled, and the backtrace will be
213 printed when attempting to lock a contended lock.
215 If in doubt, say "N".
221 Enables support for DRM clients. DRM drivers that need
222 struct drm_client_dev and its interfaces should select this
223 option. Drivers that support the default clients should
224 select DRM_CLIENT_SELECTION instead.
226 source "drivers/gpu/drm/clients/Kconfig"
228 config DRM_LOAD_EDID_FIRMWARE
229 bool "Allow to specify an EDID data set instead of probing for it"
232 Say Y here, if you want to use EDID data to be loaded from the
233 /lib/firmware directory or one of the provided built-in
234 data sets. This may be necessary, if the graphics adapter or
235 monitor are unable to provide appropriate EDID data. Since this
236 feature is provided as a workaround for broken hardware, the
237 default case is N. Details and instructions how to build your own
238 EDID data are given in Documentation/admin-guide/edid.rst.
240 source "drivers/gpu/drm/display/Kconfig"

247 GPU memory types. Will be enabled automatically if a device driver

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

489 A kernel build should not cause any compiler warnings, and this
