10 select DRM_PANEL_ORIENTATION_QUIRKS
15 select DMA_SHARED_BUFFER
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_DP_AUX_CHARDEV
31 bool "DRM DP AUX Interface"
34 Choose this option to enable a /dev/drm_dp_auxN node that allows to
35 read and write values to arbitrary DPCD registers on the DP aux
39 bool "Insert extra checks and debug info into the DRM range managers"
42 depends on STACKTRACE_SUPPORT
45 Enable allocation tracking of memory manager and leak detection on
48 Recommended for driver developers only.
52 config DRM_DEBUG_MM_SELFTEST
53 tristate "kselftests for DRM range manager (struct drm_mm)"
55 depends on DEBUG_KERNEL
60 This option provides a kernel module that can be used to test
61 the DRM range manager (drm_mm) and its API. This option is not
62 useful for distributions or general kernels, but only for kernel
63 developers working on DRM and associated drivers.

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

292 # Keep legacy drivers last
294 menuconfig DRM_LEGACY
295 bool "Enable legacy drivers (DANGEROUS)"
296 depends on DRM && MMU
299 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
300 APIs to user-space, which can be used to circumvent access
301 restrictions and other security measures. For backwards compatibility
302 those drivers are still available, but their use is highly
303 inadvisable and might harm your system.
305 You are recommended to use the safe modeset-only drivers instead, and
306 perform 3D emulation in user-space.
308 Unless you have strong reasons to go rogue, say "N".
313 tristate "3dfx Banshee/Voodoo3+"
314 depends on DRM && PCI
316 Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
317 graphics card. If M is selected, the module will be called tdfx.
320 tristate "ATI Rage 128"
321 depends on DRM && PCI
324 Choose this option if you have an ATI Rage 128 graphics card. If M
325 is selected, the module will be called r128. AGP support for
326 this card is strongly suggested (unless you have a PCI version).
329 tristate "Intel I810"
330 # !PREEMPT because of missing ioctl locking
331 depends on DRM && AGP && AGP_INTEL && (!PREEMPT || BROKEN)
333 Choose this option if you have an Intel I810 graphics card. If M is
334 selected, the module will be called i810. AGP support is required
335 for this driver to work.
338 tristate "Matrox g200/g400"
339 depends on DRM && PCI
342 Choose this option if you have a Matrox G200, G400 or G450 graphics
343 card. If M is selected, the module will be called mga. AGP
344 support is required for this driver to work.
347 tristate "SiS video cards"
348 depends on DRM && AGP
349 depends on FB_SIS || FB_SIS=n
351 Choose this option if you have a SiS 630 or compatible video
352 chipset. If M is selected the module will be called sis. AGP
353 support is required for this driver to work.
356 tristate "Via unichrome video cards"
357 depends on DRM && PCI
359 Choose this option if you have a Via unichrome or compatible video
360 chipset. If M is selected the module will be called via.
363 tristate "Savage video cards"
364 depends on DRM && PCI
366 Choose this option if you have a Savage3D/4/SuperSavage/Pro/Twister
367 chipset. If M is selected the module will be called savage.
