22 Kernel-level support for the Direct Rendering Infrastructure (DRI)
23 introduced in XFree86 4.0. If you say Y here, you need to select
24 the module that's right for your graphics card from the list below.
25 These modules provide support for synchronization, security, and
26 DMA transfers. Please see <http://dri.sourceforge.net/> for more
27 details. You should also select and configure AGP
28 (/dev/agpgart) support if it is available for your platform.

39 bool "DRM DP AUX Interface"
42 Choose this option to enable a /dev/drm_dp_auxN node that allows to
43 read and write values to arbitrary DPCD registers on the DP aux

67 select DRM_EXPORT_FOR_TESTS if m
70 This option provides kernel modules that can be used to run
71 various selftests on parts of the DRM api. This option is not
72 useful for distributions or general kernels, but only for kernel
73 developers working on DRM and associated drivers.

84 bool "Enable refcount backtrace history in the DP MST helpers"
85 depends on STACKTRACE_SUPPORT
87 depends on DRM_KMS_HELPER
88 depends on DEBUG_KERNEL
91 Enables debug tracing for topology refs in DRM's DP MST helpers. A
92 history of each topology reference/dereference will be printed to the
93 kernel log once a port or branch device's topology refcount reaches 0.
95 This has the potential to use a lot of memory and print some very
96 large kernel messages. If in doubt, say "N".

118 support on top of your modesetting driver.

122 config DRM_FBDEV_OVERALLOC
123 int "Overallocation of the fbdev buffer"
124 depends on DRM_FBDEV_EMULATION
127 Defines the fbdev buffer overallocation in percent. Default
128 is 100. Typical values for double buffering will be 200,
129 triple buffering 300.
131 config DRM_FBDEV_LEAK_PHYS_SMEM
132 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
133 depends on DRM_FBDEV_EMULATION && EXPERT
136 In order to keep user-space compatibility, we want in certain
137 use-cases to keep leaking the fbdev physical address to the
138 user-space program handling the fbdev buffer.
139 This affects, not only, Amlogic, Allwinner or Rockchip devices
140 with ARM Mali GPUs using an userspace Blob.
141 This option is not supported by upstream developers and should be
142 removed as soon as possible and be considered as a broken and
143 legacy behaviour from a modern fbdev device driver.
145 Please send any bug reports when using this to your proprietary
146 software vendor that requires this.
148 If in doubt, say "N" or spread the word to your closed source
151 config DRM_LOAD_EDID_FIRMWARE
152 bool "Allow to specify an EDID data set instead of probing for it"
155 Say Y here, if you want to use EDID data to be loaded from the
156 /lib/firmware directory or one of the provided built-in
157 data sets. This may be necessary, if the graphics adapter or
158 monitor are unable to provide appropriate EDID data. Since this
159 feature is provided as a workaround for broken hardware, the
160 default case is N. Details and instructions how to build your own
161 EDID data are given in Documentation/admin-guide/edid.rst.
164 bool "Enable DisplayPort CEC-Tunneling-over-AUX HDMI support"
168 Choose this option if you want to enable HDMI CEC support for
169 DisplayPort/USB-C to HDMI adapters.
171 Note: not all adapters support this feature, and even for those
172 that do support this they often do not hook up the CEC pin.

386 bool "Enable legacy drivers (DANGEROUS)"
387 depends on DRM && MMU
389 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
390 APIs to user-space, which can be used to circumvent access
391 restrictions and other security measures. For backwards compatibility
392 those drivers are still available, but their use is highly
393 inadvisable and might harm your system.
395 You are recommended to use the safe modeset-only drivers instead, and
396 perform 3D emulation in user-space.
398 Unless you have strong reasons to go rogue, say "N".
