22	  Choose this option if you have a system that has "Intel Graphics
23	  Media Accelerator" or "HD Graphics" integrated graphics,
24	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
25	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
26	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.
27	  If M is selected, the module will be called i915.  AGP support
28	  is required for this driver to work. This driver is used by
29	  the Intel driver in X.org 6.8 and XFree86 4.4 and above. It
30	  replaces the older i830 module that supported a subset of the
31	  hardware in older X.org releases.
32
33	  Note that the older i810/i815 chipsets require the use of the
34	  i810 driver instead, and the Atom z5xx series has an entirely
35	  different implementation.
36
37config DRM_I915_PRELIMINARY_HW_SUPPORT
38	bool "Enable preliminary support for prerelease Intel hardware by default"
39	depends on DRM_I915
40	default n
41	help
42	  Choose this option if you have prerelease Intel hardware and want the
43	  i915 driver to support it by default.  You can enable such support at
44	  runtime with the module option i915.preliminary_hw_support=1; this
45	  option changes the default for that module option.
46
47	  If in doubt, say "N".
48
49config DRM_I915_CAPTURE_ERROR
50	bool "Enable capturing GPU state following a hang"
51	depends on DRM_I915
52	default y
53	help
54	  This option enables capturing the GPU state when a hang is detected.
55	  This information is vital for triaging hangs and assists in debugging.
56	  Please report any hang to
57            https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
58	  for triaging.
59
60	  If in doubt, say "Y".

62config DRM_I915_COMPRESS_ERROR
63	bool "Compress GPU error state"
64	depends on DRM_I915_CAPTURE_ERROR
65	select ZLIB_DEFLATE
66	default y
67	help
68	  This option selects ZLIB_DEFLATE if it isn't already
69	  selected and causes any error state captured upon a GPU hang
70	  to be compressed using zlib.
71
72	  If in doubt, say "Y".
73
74config DRM_I915_USERPTR
75	bool "Always enable userptr support"
76	depends on DRM_I915
77	select MMU_NOTIFIER
78	default y
79	help
80	  This option selects CONFIG_MMU_NOTIFIER if it isn't already
81	  selected to enabled full userptr support.
82
83	  If in doubt, say "Y".
84
85config DRM_I915_GVT
86        bool "Enable Intel GVT-g graphics virtualization host support"
87        depends on DRM_I915
88        default n
89        help
90	  Choose this option if you want to enable Intel GVT-g graphics
91	  virtualization technology host support with integrated graphics.
92	  With GVT-g, it's possible to have one integrated graphics
93	  device shared by multiple VMs under different hypervisors.
94
95	  Note that at least one hypervisor like Xen or KVM is required for
96	  this driver to work, and it only supports newer device from
97	  Broadwell+. For further information and setup guide, you can
98	  visit: http://01.org/igvt-g.
99
100	  Now it's just a stub to support the modifications of i915 for
101	  GVT device model. It requires at least one MPT modules for Xen/KVM
102	  and other components of GVT device model to work. Use it under
103	  you own risk.
104
105	  If in doubt, say "N".
