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

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

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

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

390 bool "Enable legacy drivers (DANGEROUS)"
391 depends on DRM && MMU
394 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
395 APIs to user-space, which can be used to circumvent access
396 restrictions and other security measures. For backwards compatibility
397 those drivers are still available, but their use is highly
398 inadvisable and might harm your system.
400 You are recommended to use the safe modeset-only drivers instead, and
401 perform 3D emulation in user-space.
403 Unless you have strong reasons to go rogue, say "N".
408 tristate "3dfx Banshee/Voodoo3+"

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

428 Choose this option if you have an Intel I810 graphics card. If M is
429 selected, the module will be called i810. AGP support is required
430 for this driver to work.
433 tristate "Matrox g200/g400"
434 depends on DRM && PCI
437 Choose this option if you have a Matrox G200, G400 or G450 graphics
438 card. If M is selected, the module will be called mga. AGP
439 support is required for this driver to work.
442 tristate "SiS video cards"
443 depends on DRM && AGP
444 depends on FB_SIS || FB_SIS=n
446 Choose this option if you have a SiS 630 or compatible video

448 support is required for this driver to work.
451 tristate "Via unichrome video cards"
452 depends on DRM && PCI
454 Choose this option if you have a Via unichrome or compatible video
455 chipset. If M is selected the module will be called via.
