18 Kernel-level support for the Direct Rendering Infrastructure (DRI)
19 introduced in XFree86 4.0. If you say Y here, you need to select
20 the module that's right for your graphics card from the list below.
21 These modules provide support for synchronization, security, and
22 DMA transfers. Please see <http://dri.sourceforge.net/> for more
23 details. You should also select and configure AGP
24 (/dev/agpgart) support if it is available for your platform.
30 config DRM_DP_AUX_CHARDEV
31 bool "DRM DP AUX Interface"
34 Choose this option to enable a /dev/drm_dp_auxN node that allows to
35 read and write values to arbitrary DPCD registers on the DP aux
39 bool "Insert extra checks and debug info into the DRM range managers"
42 depends on STACKTRACE_SUPPORT
45 Enable allocation tracking of memory manager and leak detection on
48 Recommended for driver developers only.
52 config DRM_DEBUG_SELFTEST
53 tristate "kselftests for DRM"
55 depends on DEBUG_KERNEL
61 This option provides kernel modules that can be used to run
62 various selftests on parts of the DRM api. This option is not
63 useful for distributions or general kernels, but only for kernel
64 developers working on DRM and associated drivers.
72 CRTC helpers for KMS drivers.

92 bool "Enable legacy fbdev support for your modesetting driver"
95 select DRM_KMS_FB_HELPER
98 Choose this option if you have a need for the legacy fbdev
99 support. Note that this support also provides the linux console
100 support on top of your modesetting driver.
102 If in doubt, say "Y".
104 config DRM_FBDEV_OVERALLOC
105 int "Overallocation of the fbdev buffer"
106 depends on DRM_FBDEV_EMULATION
109 Defines the fbdev buffer overallocation in percent. Default
110 is 100. Typical values for double buffering will be 200,
111 triple buffering 300.
113 config DRM_LOAD_EDID_FIRMWARE
114 bool "Allow to specify an EDID data set instead of probing for it"
117 Say Y here, if you want to use EDID data to be loaded from the
118 /lib/firmware directory or one of the provided built-in
119 data sets. This may be necessary, if the graphics adapter or
120 monitor are unable to provide appropriate EDID data. Since this
121 feature is provided as a workaround for broken hardware, the
122 default case is N. Details and instructions how to build your own
123 EDID data are given in Documentation/EDID/HOWTO.txt.
126 bool "Enable DisplayPort CEC-Tunneling-over-AUX HDMI support"
129 Choose this option if you want to enable HDMI CEC support for
130 DisplayPort/USB-C to HDMI adapters.
132 Note: not all adapters support this feature, and even for those
133 that do support this they often do not hook up the CEC pin.

321 bool "Enable legacy drivers (DANGEROUS)"
322 depends on DRM && MMU
325 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
326 APIs to user-space, which can be used to circumvent access
327 restrictions and other security measures. For backwards compatibility
328 those drivers are still available, but their use is highly
329 inadvisable and might harm your system.
331 You are recommended to use the safe modeset-only drivers instead, and
332 perform 3D emulation in user-space.
334 Unless you have strong reasons to go rogue, say "N".
339 tristate "3dfx Banshee/Voodoo3+"
340 depends on DRM && PCI
342 Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
343 graphics card. If M is selected, the module will be called tdfx.
346 tristate "ATI Rage 128"
347 depends on DRM && PCI
350 Choose this option if you have an ATI Rage 128 graphics card. If M
351 is selected, the module will be called r128. AGP support for
352 this card is strongly suggested (unless you have a PCI version).
355 tristate "Intel I810"
356 # !PREEMPT because of missing ioctl locking
357 depends on DRM && AGP && AGP_INTEL && (!PREEMPT || BROKEN)
359 Choose this option if you have an Intel I810 graphics card. If M is
360 selected, the module will be called i810. AGP support is required
361 for this driver to work.
364 tristate "Matrox g200/g400"
365 depends on DRM && PCI
368 Choose this option if you have a Matrox G200, G400 or G450 graphics
369 card. If M is selected, the module will be called mga. AGP
370 support is required for this driver to work.
373 tristate "SiS video cards"
374 depends on DRM && AGP
375 depends on FB_SIS || FB_SIS=n
377 Choose this option if you have a SiS 630 or compatible video
378 chipset. If M is selected the module will be called sis. AGP
379 support is required for this driver to work.
382 tristate "Via unichrome video cards"
383 depends on DRM && PCI
385 Choose this option if you have a Via unichrome or compatible video
386 chipset. If M is selected the module will be called via.
389 tristate "Savage video cards"
390 depends on DRM && PCI
392 Choose this option if you have a Savage3D/4/SuperSavage/Pro/Twister
