19 Kernel-level support for the Direct Rendering Infrastructure (DRI)
20 introduced in XFree86 4.0. If you say Y here, you need to select
21 the module that's right for your graphics card from the list below.
22 These modules provide support for synchronization, security, and
23 DMA transfers. Please see <http://dri.sourceforge.net/> for more
24 details. You should also select and configure AGP
25 (/dev/agpgart) support if it is available for your platform.
35 config DRM_DP_AUX_CHARDEV
36 bool "DRM DP AUX Interface"
39 Choose this option to enable a /dev/drm_dp_auxN node that allows to
40 read and write values to arbitrary DPCD registers on the DP aux
44 bool "Insert extra checks and debug info into the DRM range managers"

67 This option provides kernel modules that can be used to run
68 various selftests on parts of the DRM api. This option is not
69 useful for distributions or general kernels, but only for kernel

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

120 support. Note that this support also provides the linux console
121 support on top of your modesetting driver.

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

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

428 for this driver to work.
431 tristate "Matrox g200/g400"
