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

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.

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

115 bool "Enable legacy fbdev support for your modesetting driver"
117 select DRM_KMS_HELPER

121 Choose this option if you have a need for the legacy fbdev
122 support. Note that this support also provides the linux console
123 support on top of your modesetting driver.

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

399 select DRM_ATI_PCIGART if PCI
401 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
402 APIs to user-space, which can be used to circumvent access
403 restrictions and other security measures. For backwards compatibility
404 those drivers are still available, but their use is highly
405 inadvisable and might harm your system.
407 You are recommended to use the safe modeset-only drivers instead, and
408 perform 3D emulation in user-space.

437 for this driver to work.
