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"
47 depends on STACKTRACE_SUPPORT
50 Enable allocation tracking of memory manager and leak detection on

58 tristate "kselftests for DRM"
60 depends on DEBUG_KERNEL
66 This option provides kernel modules that can be used to run
67 various selftests on parts of the DRM api. This option is not
68 useful for distributions or general kernels, but only for kernel
69 developers working on DRM and associated drivers.

97 bool "Enable refcount backtrace history in the DP MST helpers"
99 depends on DRM_KMS_HELPER
100 depends on DEBUG_KERNEL
103 Enables debug tracing for topology refs in DRM's DP MST helpers. A
104 history of each topology reference/dereference will be printed to the
105 kernel log once a port or branch device's topology refcount reaches 0.
107 This has the potential to use a lot of memory and print some very
108 large kernel messages. If in doubt, say "N".
110 config DRM_FBDEV_EMULATION
111 bool "Enable legacy fbdev support for your modesetting driver"
113 select DRM_KMS_HELPER
114 select DRM_KMS_FB_HELPER
117 Choose this option if you have a need for the legacy fbdev
118 support. Note that this support also provides the linux console
119 support on top of your modesetting driver.
121 If in doubt, say "Y".
123 config DRM_FBDEV_OVERALLOC
124 int "Overallocation of the fbdev buffer"
125 depends on DRM_FBDEV_EMULATION
128 Defines the fbdev buffer overallocation in percent. Default
129 is 100. Typical values for double buffering will be 200,
130 triple buffering 300.
132 config DRM_FBDEV_LEAK_PHYS_SMEM
133 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
134 depends on DRM_FBDEV_EMULATION && EXPERT
137 In order to keep user-space compatibility, we want in certain
138 use-cases to keep leaking the fbdev physical address to the
139 user-space program handling the fbdev buffer.
140 This affects, not only, Amlogic, Allwinner or Rockchip devices
141 with ARM Mali GPUs using an userspace Blob.
142 This option is not supported by upstream developers and should be
143 removed as soon as possible and be considered as a broken and
144 legacy behaviour from a modern fbdev device driver.
146 Please send any bug reports when using this to your proprietary
147 software vendor that requires this.
149 If in doubt, say "N" or spread the word to your closed source
152 config DRM_LOAD_EDID_FIRMWARE
153 bool "Allow to specify an EDID data set instead of probing for it"
156 Say Y here, if you want to use EDID data to be loaded from the
157 /lib/firmware directory or one of the provided built-in
158 data sets. This may be necessary, if the graphics adapter or
159 monitor are unable to provide appropriate EDID data. Since this
160 feature is provided as a workaround for broken hardware, the
161 default case is N. Details and instructions how to build your own
162 EDID data are given in Documentation/driver-api/edid.rst.
165 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.

395 select DRM_ATI_PCIGART if PCI
397 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
398 APIs to user-space, which can be used to circumvent access
399 restrictions and other security measures. For backwards compatibility
400 those drivers are still available, but their use is highly
401 inadvisable and might harm your system.
403 You are recommended to use the safe modeset-only drivers instead, and
404 perform 3D emulation in user-space.
406 Unless you have strong reasons to go rogue, say "N".

433 for this driver to work.
436 tristate "Matrox g200/g400"
437 depends on DRM && PCI
440 Choose this option if you have a Matrox G200, G400 or G450 graphics
