9 depends on (AGP || AGP=n) && !EMULATED_CMPXCHG && HAS_DMA
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_DP_AUX_CHARDEV
30 bool "DRM DP AUX Interface"
33 Choose this option to enable a /dev/drm_dp_auxN node that allows to
34 read and write values to arbitrary DPCD registers on the DP aux
38 bool "Insert extra checks and debug info into the DRM range managers"
41 depends on STACKTRACE_SUPPORT
44 Enable allocation tracking of memory manager and leak detection on

51 config DRM_DEBUG_MM_SELFTEST
52 tristate "kselftests for DRM range manager (struct drm_mm)"
54 depends on DEBUG_KERNEL
59 This option provides a kernel module that can be used to test
60 the DRM range manager (drm_mm) and its API. This option is not
61 useful for distributions or general kernels, but only for kernel
62 developers working on DRM and associated drivers.

90 bool "Enable legacy fbdev support for your modesetting driver"
93 select DRM_KMS_FB_HELPER

102 config DRM_LOAD_EDID_FIRMWARE
103 bool "Allow to specify an EDID data set instead of probing for it"
104 depends on DRM_KMS_HELPER
106 Say Y here, if you want to use EDID data to be loaded from the
107 /lib/firmware directory or one of the provided built-in
108 data sets. This may be necessary, if the graphics adapter or
109 monitor are unable to provide appropriate EDID data. Since this
110 feature is provided as a workaround for broken hardware, the
111 default case is N. Details and instructions how to build your own
112 EDID data are given in Documentation/EDID/HOWTO.txt.

266 # Keep legacy drivers last
268 menuconfig DRM_LEGACY
269 bool "Enable legacy drivers (DANGEROUS)"
270 depends on DRM && MMU
273 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
274 APIs to user-space, which can be used to circumvent access
275 restrictions and other security measures. For backwards compatibility
276 those drivers are still available, but their use is highly
277 inadvisable and might harm your system.
279 You are recommended to use the safe modeset-only drivers instead, and
280 perform 3D emulation in user-space.
282 Unless you have strong reasons to go rogue, say "N".
287 tristate "3dfx Banshee/Voodoo3+"
288 depends on DRM && PCI

295 depends on DRM && PCI
298 Choose this option if you have an ATI Rage 128 graphics card. If M
299 is selected, the module will be called r128. AGP support for
300 this card is strongly suggested (unless you have a PCI version).

305 depends on DRM && AGP && AGP_INTEL && (!PREEMPT || BROKEN)
307 Choose this option if you have an Intel I810 graphics card. If M is
308 selected, the module will be called i810. AGP support is required
309 for this driver to work.
312 tristate "Matrox g200/g400"
313 depends on DRM && PCI
316 Choose this option if you have a Matrox G200, G400 or G450 graphics
317 card. If M is selected, the module will be called mga. AGP
318 support is required for this driver to work.
