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_PANEL_ORIENTATION_QUIRKS
33 config DRM_DP_AUX_CHARDEV
34 bool "DRM DP AUX Interface"
37 Choose this option to enable a /dev/drm_dp_auxN node that allows to
38 read and write values to arbitrary DPCD registers on the DP aux
42 bool "Insert extra checks and debug info into the DRM range managers"
45 depends on STACKTRACE_SUPPORT
48 Enable allocation tracking of memory manager and leak detection on
51 Recommended for driver developers only.
55 config DRM_DEBUG_MM_SELFTEST
56 tristate "kselftests for DRM range manager (struct drm_mm)"
58 depends on DEBUG_KERNEL
63 This option provides a kernel module that can be used to test
64 the DRM range manager (drm_mm) and its API. This option is not
65 useful for distributions or general kernels, but only for kernel
66 developers working on DRM and associated drivers.
74 CRTC helpers for KMS drivers.

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

290 # Keep legacy drivers last

293 bool "Enable legacy drivers (DANGEROUS)"
294 depends on DRM && MMU
297 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
298 APIs to user-space, which can be used to circumvent access
299 restrictions and other security measures. For backwards compatibility
300 those drivers are still available, but their use is highly
301 inadvisable and might harm your system.
303 You are recommended to use the safe modeset-only drivers instead, and
304 perform 3D emulation in user-space.
306 Unless you have strong reasons to go rogue, say "N".
311 tristate "3dfx Banshee/Voodoo3+"
312 depends on DRM && PCI
314 Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
315 graphics card. If M is selected, the module will be called tdfx.
318 tristate "ATI Rage 128"
319 depends on DRM && PCI
322 Choose this option if you have an ATI Rage 128 graphics card. If M
323 is selected, the module will be called r128. AGP support for
324 this card is strongly suggested (unless you have a PCI version).
327 tristate "Intel I810"
328 # !PREEMPT because of missing ioctl locking
329 depends on DRM && AGP && AGP_INTEL && (!PREEMPT || BROKEN)
331 Choose this option if you have an Intel I810 graphics card. If M is
332 selected, the module will be called i810. AGP support is required
333 for this driver to work.
336 tristate "Matrox g200/g400"
337 depends on DRM && PCI
340 Choose this option if you have a Matrox G200, G400 or G450 graphics
341 card. If M is selected, the module will be called mga. AGP
342 support is required for this driver to work.
345 tristate "SiS video cards"
346 depends on DRM && AGP
347 depends on FB_SIS || FB_SIS=n
349 Choose this option if you have a SiS 630 or compatible video
350 chipset. If M is selected the module will be called sis. AGP
351 support is required for this driver to work.
354 tristate "Via unichrome video cards"
355 depends on DRM && PCI
357 Choose this option if you have a Via unichrome or compatible video
358 chipset. If M is selected the module will be called via.
