25	  Choose this option if you have a system that has "Intel Graphics
26	  Media Accelerator" or "HD Graphics" integrated graphics,
27	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
28	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
29	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.

31	  This driver is used by the Intel driver in X.org 6.8 and
32	  XFree86 4.4 and above. It replaces the older i830 module that
33	  supported a subset of the hardware in older X.org releases.
34
35	  Note that the older i810/i815 chipsets require the use of the
36	  i810 driver instead, and the Atom z5xx series has an entirely
37	  different implementation.
38
39	  If "M" is selected, the module will be called i915.

41config DRM_I915_ALPHA_SUPPORT
42	bool "Enable alpha quality support for new Intel hardware by default"
43	depends on DRM_I915
44	default n
45	help
46	  Choose this option if you have new Intel hardware and want to enable
47	  the alpha quality i915 driver support for the hardware in this kernel
48	  version. You can also enable the support at runtime using the module
49	  parameter i915.alpha_support=1; this option changes the default for
50	  that module parameter.
51
52	  It is recommended to upgrade to a kernel version with proper support
53	  as soon as it is available. Generally fixes for platforms with alpha
54	  support are not backported to older kernels.
55
56	  If in doubt, say "N".

58config DRM_I915_CAPTURE_ERROR
59	bool "Enable capturing GPU state following a hang"
60	depends on DRM_I915
61	default y
62	help
63	  This option enables capturing the GPU state when a hang is detected.
64	  This information is vital for triaging hangs and assists in debugging.
65	  Please report any hang to
66            https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
67	  for triaging.
68
69	  If in doubt, say "Y".

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