27	  Choose this option if you have a system that has "Intel Graphics
28	  Media Accelerator" or "HD Graphics" integrated graphics,
29	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
30	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
31	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.
32
33	  This driver is used by the Intel driver in X.org 6.8 and
34	  XFree86 4.4 and above. It replaces the older i830 module that
35	  supported a subset of the hardware in older X.org releases.
36
37	  Note that the older i810/i815 chipsets require the use of the
38	  i810 driver instead, and the Atom z5xx series has an entirely
39	  different implementation.
40
41	  If "M" is selected, the module will be called i915.

43config DRM_I915_ALPHA_SUPPORT
44	bool "Enable alpha quality support for new Intel hardware by default"
45	depends on DRM_I915
46	default n
47	help
48	  Choose this option if you have new Intel hardware and want to enable
49	  the alpha quality i915 driver support for the hardware in this kernel
50	  version. You can also enable the support at runtime using the module
51	  parameter i915.alpha_support=1; this option changes the default for
52	  that module parameter.
53
54	  It is recommended to upgrade to a kernel version with proper support
55	  as soon as it is available. Generally fixes for platforms with alpha
56	  support are not backported to older kernels.
57
58	  If in doubt, say "N".

60config DRM_I915_CAPTURE_ERROR
61	bool "Enable capturing GPU state following a hang"
62	depends on DRM_I915
63	default y
64	help
65	  This option enables capturing the GPU state when a hang is detected.
66	  This information is vital for triaging hangs and assists in debugging.
67	  Please report any hang to
68            https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
69	  for triaging.
70
71	  If in doubt, say "Y".

74	bool "Compress GPU error state"
75	depends on DRM_I915_CAPTURE_ERROR
76	select ZLIB_DEFLATE
77	default y
78	help
79	  This option selects ZLIB_DEFLATE if it isn't already
80	  selected and causes any error state captured upon a GPU hang
81	  to be compressed using zlib.
82
83	  If in doubt, say "Y".
84
85config DRM_I915_USERPTR
86	bool "Always enable userptr support"
87	depends on DRM_I915
88	select MMU_NOTIFIER
89	default y
90	help
91	  This option selects CONFIG_MMU_NOTIFIER if it isn't already
92	  selected to enabled full userptr support.
93
94	  If in doubt, say "Y".
95
96config DRM_I915_GVT
97        bool "Enable Intel GVT-g graphics virtualization host support"
98        depends on DRM_I915
99        depends on 64BIT
100        default n
101        help
102	  Choose this option if you want to enable Intel GVT-g graphics
103	  virtualization technology host support with integrated graphics.
104	  With GVT-g, it's possible to have one integrated graphics
105	  device shared by multiple VMs under different hypervisors.
106
107	  Note that at least one hypervisor like Xen or KVM is required for
108	  this driver to work, and it only supports newer device from
109	  Broadwell+. For further information and setup guide, you can
110	  visit: http://01.org/igvt-g.
111
112	  Now it's just a stub to support the modifications of i915 for
113	  GVT device model. It requires at least one MPT modules for Xen/KVM
114	  and other components of GVT device model to work. Use it under
115	  you own risk.
116
117	  If in doubt, say "N".
