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.
31 config DRM_DP_AUX_CHARDEV
32 bool "DRM DP AUX Interface"
35 Choose this option to enable a /dev/drm_dp_auxN node that allows to
36 read and write values to arbitrary DPCD registers on the DP aux
40 bool "Insert extra checks and debug info into the DRM range managers"
43 depends on STACKTRACE_SUPPORT
46 Enable allocation tracking of memory manager and leak detection on
49 Recommended for driver developers only.

54 tristate "kselftests for DRM"
56 depends on DEBUG_KERNEL
62 This option provides kernel modules that can be used to run
63 various selftests on parts of the DRM api. This option is not
64 useful for distributions or general kernels, but only for kernel
65 developers working on DRM and associated drivers.

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

352 select DRM_ATI_PCIGART if PCI
354 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
355 APIs to user-space, which can be used to circumvent access
356 restrictions and other security measures. For backwards compatibility
357 those drivers are still available, but their use is highly
358 inadvisable and might harm your system.
360 You are recommended to use the safe modeset-only drivers instead, and
361 perform 3D emulation in user-space.
363 Unless you have strong reasons to go rogue, say "N".

376 depends on DRM && PCI
379 Choose this option if you have an ATI Rage 128 graphics card. If M
380 is selected, the module will be called r128. AGP support for
381 this card is strongly suggested (unless you have a PCI version).

390 for this driver to work.

394 depends on DRM && PCI
397 Choose this option if you have a Matrox G200, G400 or G450 graphics
