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 # Separate option because drm_panel_orientation_quirks.c is shared with fbdev
31 config DRM_PANEL_ORIENTATION_QUIRKS
34 config DRM_DP_AUX_CHARDEV
35 bool "DRM DP AUX Interface"
38 Choose this option to enable a /dev/drm_dp_auxN node that allows to
39 read and write values to arbitrary DPCD registers on the DP aux
43 bool "Insert extra checks and debug info into the DRM range managers"
46 depends on STACKTRACE_SUPPORT
49 Enable allocation tracking of memory manager and leak detection on

57 tristate "kselftests for DRM range manager (struct drm_mm)"
59 depends on DEBUG_KERNEL
64 This option provides a kernel module that can be used to test
65 the DRM range manager (drm_mm) and its API. This option is not
66 useful for distributions or general kernels, but only for kernel
67 developers working on DRM and associated drivers.

95 bool "Enable legacy fbdev support for your modesetting driver"
98 select DRM_KMS_FB_HELPER
101 Choose this option if you have a need for the legacy fbdev
102 support. Note that this support also provides the linux console
103 support on top of your modesetting driver.
105 If in doubt, say "Y".
107 config DRM_FBDEV_OVERALLOC
108 int "Overallocation of the fbdev buffer"
109 depends on DRM_FBDEV_EMULATION
112 Defines the fbdev buffer overallocation in percent. Default
113 is 100. Typical values for double buffering will be 200,
114 triple buffering 300.
116 config DRM_LOAD_EDID_FIRMWARE
117 bool "Allow to specify an EDID data set instead of probing for it"
120 Say Y here, if you want to use EDID data to be loaded from the
121 /lib/firmware directory or one of the provided built-in
122 data sets. This may be necessary, if the graphics adapter or
123 monitor are unable to provide appropriate EDID data. Since this
124 feature is provided as a workaround for broken hardware, the
125 default case is N. Details and instructions how to build your own
126 EDID data are given in Documentation/EDID/HOWTO.txt.

294 bool "Enable legacy drivers (DANGEROUS)"
295 depends on DRM && MMU
298 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
299 APIs to user-space, which can be used to circumvent access
300 restrictions and other security measures. For backwards compatibility
301 those drivers are still available, but their use is highly
302 inadvisable and might harm your system.
304 You are recommended to use the safe modeset-only drivers instead, and
305 perform 3D emulation in user-space.
307 Unless you have strong reasons to go rogue, say "N".
312 tristate "3dfx Banshee/Voodoo3+"

323 Choose this option if you have an ATI Rage 128 graphics card. If M
324 is selected, the module will be called r128. AGP support for
325 this card is strongly suggested (unless you have a PCI version).

332 Choose this option if you have an Intel I810 graphics card. If M is
333 selected, the module will be called i810. AGP support is required
334 for this driver to work.
337 tristate "Matrox g200/g400"
338 depends on DRM && PCI
341 Choose this option if you have a Matrox G200, G400 or G450 graphics
342 card. If M is selected, the module will be called mga. AGP
343 support is required for this driver to work.
