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.

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.

300 bool "Enable legacy drivers (DANGEROUS)"
301 depends on DRM && MMU
304 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
305 APIs to user-space, which can be used to circumvent access
306 restrictions and other security measures. For backwards compatibility
307 those drivers are still available, but their use is highly
308 inadvisable and might harm your system.
310 You are recommended to use the safe modeset-only drivers instead, and
311 perform 3D emulation in user-space.
313 Unless you have strong reasons to go rogue, say "N".
318 tristate "3dfx Banshee/Voodoo3+"
319 depends on DRM && PCI
321 Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
322 graphics card. If M is selected, the module will be called tdfx.
325 tristate "ATI Rage 128"
326 depends on DRM && PCI
329 Choose this option if you have an ATI Rage 128 graphics card. If M
330 is selected, the module will be called r128. AGP support for
331 this card is strongly suggested (unless you have a PCI version).
334 tristate "Intel I810"
335 # !PREEMPT because of missing ioctl locking
336 depends on DRM && AGP && AGP_INTEL && (!PREEMPT || BROKEN)
338 Choose this option if you have an Intel I810 graphics card. If M is
339 selected, the module will be called i810. AGP support is required
340 for this driver to work.
343 tristate "Matrox g200/g400"
344 depends on DRM && PCI
347 Choose this option if you have a Matrox G200, G400 or G450 graphics
348 card. If M is selected, the module will be called mga. AGP
349 support is required for this driver to work.
352 tristate "SiS video cards"
353 depends on DRM && AGP
354 depends on FB_SIS || FB_SIS=n
356 Choose this option if you have a SiS 630 or compatible video

364 Choose this option if you have a Via unichrome or compatible video
365 chipset. If M is selected the module will be called via.
368 tristate "Savage video cards"
369 depends on DRM && PCI
371 Choose this option if you have a Savage3D/4/SuperSavage/Pro/Twister
