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.

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

367 select DRM_ATI_PCIGART if PCI
369 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
370 APIs to user-space, which can be used to circumvent access
371 restrictions and other security measures. For backwards compatibility
372 those drivers are still available, but their use is highly
373 inadvisable and might harm your system.
375 You are recommended to use the safe modeset-only drivers instead, and
376 perform 3D emulation in user-space.
378 Unless you have strong reasons to go rogue, say "N".

405 for this driver to work.
