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

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

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

75	bool "Compress GPU error state"
76	depends on DRM_I915_CAPTURE_ERROR
77	select ZLIB_DEFLATE
78	default y
79	help
80	  This option selects ZLIB_DEFLATE if it isn't already
81	  selected and causes any error state captured upon a GPU hang
82	  to be compressed using zlib.
83
84	  If in doubt, say "Y".
85
86config DRM_I915_USERPTR
87	bool "Always enable userptr support"
88	depends on DRM_I915
89	select MMU_NOTIFIER
90	default y
91	help
92	  This option selects CONFIG_MMU_NOTIFIER if it isn't already
93	  selected to enabled full userptr support.
94
95	  If in doubt, say "Y".

97config DRM_I915_GVT
98        bool "Enable Intel GVT-g graphics virtualization host support"

100        depends on 64BIT
101        default n
102        help
103	  Choose this option if you want to enable Intel GVT-g graphics
104	  virtualization technology host support with integrated graphics.
105	  With GVT-g, it's possible to have one integrated graphics
106	  device shared by multiple VMs under different hypervisors.
107
108	  Note that at least one hypervisor like Xen or KVM is required for
109	  this driver to work, and it only supports newer device from
110	  Broadwell+. For further information and setup guide, you can
111	  visit: http://01.org/igvt-g.
112
113	  Now it's just a stub to support the modifications of i915 for
114	  GVT device model. It requires at least one MPT modules for Xen/KVM
115	  and other components of GVT device model to work. Use it under
116	  you own risk.
117
118	  If in doubt, say "N".
