14 select DMA_SHARED_BUFFER
17 Kernel-level support for the Direct Rendering Infrastructure (DRI)
18 introduced in XFree86 4.0. If you say Y here, you need to select
19 the module that's right for your graphics card from the list below.
20 These modules provide support for synchronization, security, and
21 DMA transfers. Please see <http://dri.sourceforge.net/> for more
22 details. You should also select and configure AGP
23 (/dev/agpgart) support if it is available for your platform.
29 config DRM_PANEL_ORIENTATION_QUIRKS
32 config DRM_DP_AUX_CHARDEV
33 bool "DRM DP AUX Interface"
36 Choose this option to enable a /dev/drm_dp_auxN node that allows to
37 read and write values to arbitrary DPCD registers on the DP aux
41 bool "Insert extra checks and debug info into the DRM range managers"
44 depends on STACKTRACE_SUPPORT
47 Enable allocation tracking of memory manager and leak detection on
50 Recommended for driver developers only.
54 config DRM_DEBUG_MM_SELFTEST
55 tristate "kselftests for DRM range manager (struct drm_mm)"
57 depends on DEBUG_KERNEL
62 This option provides a kernel module that can be used to test
63 the DRM range manager (drm_mm) and its API. This option is not
64 useful for distributions or general kernels, but only for kernel
65 developers working on DRM and associated drivers.
73 CRTC helpers for KMS drivers.

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

289 # Keep legacy drivers last
291 menuconfig DRM_LEGACY
292 bool "Enable legacy drivers (DANGEROUS)"
293 depends on DRM && MMU
296 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
297 APIs to user-space, which can be used to circumvent access
298 restrictions and other security measures. For backwards compatibility
299 those drivers are still available, but their use is highly
300 inadvisable and might harm your system.
302 You are recommended to use the safe modeset-only drivers instead, and
303 perform 3D emulation in user-space.
305 Unless you have strong reasons to go rogue, say "N".
310 tristate "3dfx Banshee/Voodoo3+"
311 depends on DRM && PCI
313 Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
314 graphics card. If M is selected, the module will be called tdfx.
317 tristate "ATI Rage 128"
318 depends on DRM && PCI
321 Choose this option if you have an ATI Rage 128 graphics card. If M
322 is selected, the module will be called r128. AGP support for
323 this card is strongly suggested (unless you have a PCI version).
326 tristate "Intel I810"
327 # !PREEMPT because of missing ioctl locking
328 depends on DRM && AGP && AGP_INTEL && (!PREEMPT || BROKEN)
330 Choose this option if you have an Intel I810 graphics card. If M is
331 selected, the module will be called i810. AGP support is required
332 for this driver to work.
335 tristate "Matrox g200/g400"
336 depends on DRM && PCI
339 Choose this option if you have a Matrox G200, G400 or G450 graphics
340 card. If M is selected, the module will be called mga. AGP
341 support is required for this driver to work.
344 tristate "SiS video cards"
345 depends on DRM && AGP
346 depends on FB_SIS || FB_SIS=n
348 Choose this option if you have a SiS 630 or compatible video

350 support is required for this driver to work.
353 tristate "Via unichrome video cards"
354 depends on DRM && PCI
