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
47 Recommended for driver developers only.
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.

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

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

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