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_SELFTEST
53 tristate "kselftests for DRM"
55 depends on DEBUG_KERNEL
61 This option provides kernel modules that can be used to run
62 various selftests on parts of the DRM api. This option is not
63 useful for distributions or general kernels, but only for kernel
64 developers working on DRM and associated drivers.
72 CRTC helpers for KMS drivers.

91 config DRM_FBDEV_EMULATION
92 bool "Enable legacy fbdev support for your modesetting driver"
95 select DRM_KMS_FB_HELPER
98 Choose this option if you have a need for the legacy fbdev
99 support. Note that this support also provides the linux console
100 support on top of your modesetting driver.
102 If in doubt, say "Y".
104 config DRM_FBDEV_OVERALLOC
105 int "Overallocation of the fbdev buffer"
106 depends on DRM_FBDEV_EMULATION
109 Defines the fbdev buffer overallocation in percent. Default
110 is 100. Typical values for double buffering will be 200,
111 triple buffering 300.
113 config DRM_FBDEV_LEAK_PHYS_SMEM
114 bool "Shamelessly allow leaking of fbdev physical address (DANGEROUS)"
115 depends on DRM_FBDEV_EMULATION && EXPERT
118 In order to keep user-space compatibility, we want in certain
119 use-cases to keep leaking the fbdev physical address to the
120 user-space program handling the fbdev buffer.
121 This affects, not only, Amlogic, Allwinner or Rockchip devices
122 with ARM Mali GPUs using an userspace Blob.
123 This option is not supported by upstream developers and should be
124 removed as soon as possible and be considered as a broken and
125 legacy behaviour from a modern fbdev device driver.
127 Please send any bug reports when using this to your proprietary
128 software vendor that requires this.
130 If in doubt, say "N" or spread the word to your closed source
133 config DRM_LOAD_EDID_FIRMWARE
134 bool "Allow to specify an EDID data set instead of probing for it"
137 Say Y here, if you want to use EDID data to be loaded from the
138 /lib/firmware directory or one of the provided built-in
139 data sets. This may be necessary, if the graphics adapter or
140 monitor are unable to provide appropriate EDID data. Since this
141 feature is provided as a workaround for broken hardware, the
142 default case is N. Details and instructions how to build your own
143 EDID data are given in Documentation/EDID/HOWTO.txt.
146 bool "Enable DisplayPort CEC-Tunneling-over-AUX HDMI support"
149 Choose this option if you want to enable HDMI CEC support for
150 DisplayPort/USB-C to HDMI adapters.
152 Note: not all adapters support this feature, and even for those
153 that do support this they often do not hook up the CEC pin.

160 GPU memory types. Will be enabled automatically if a device driver

344 # Keep legacy drivers last

347 bool "Enable legacy drivers (DANGEROUS)"
348 depends on DRM && MMU
351 Enable legacy DRI1 drivers. Those drivers expose unsafe and dangerous
352 APIs to user-space, which can be used to circumvent access
353 restrictions and other security measures. For backwards compatibility
354 those drivers are still available, but their use is highly
355 inadvisable and might harm your system.
357 You are recommended to use the safe modeset-only drivers instead, and
358 perform 3D emulation in user-space.
360 Unless you have strong reasons to go rogue, say "N".
365 tristate "3dfx Banshee/Voodoo3+"
366 depends on DRM && PCI
368 Choose this option if you have a 3dfx Banshee or Voodoo3 (or later),
369 graphics card. If M is selected, the module will be called tdfx.
372 tristate "ATI Rage 128"
373 depends on DRM && PCI
376 Choose this option if you have an ATI Rage 128 graphics card. If M
377 is selected, the module will be called r128. AGP support for
378 this card is strongly suggested (unless you have a PCI version).
381 tristate "Intel I810"
382 # !PREEMPT because of missing ioctl locking
383 depends on DRM && AGP && AGP_INTEL && (!PREEMPT || BROKEN)
385 Choose this option if you have an Intel I810 graphics card. If M is
386 selected, the module will be called i810. AGP support is required
387 for this driver to work.
390 tristate "Matrox g200/g400"
391 depends on DRM && PCI
394 Choose this option if you have a Matrox G200, G400 or G450 graphics
395 card. If M is selected, the module will be called mga. AGP
396 support is required for this driver to work.
399 tristate "SiS video cards"
400 depends on DRM && AGP
401 depends on FB_SIS || FB_SIS=n
