23	  Choose this option if you have a system that has "Intel Graphics
24	  Media Accelerator" or "HD Graphics" integrated graphics,
25	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
26	  G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
27	  Core i5, Core i7 as well as Atom CPUs with integrated graphics.
28
29	  This driver is used by the Intel driver in X.org 6.8 and
30	  XFree86 4.4 and above. It replaces the older i830 module that
31	  supported a subset of the 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
37	  If "M" is selected, the module will be called i915.

39config DRM_I915_ALPHA_SUPPORT
40	bool "Enable alpha quality support for new Intel hardware by default"
41	depends on DRM_I915
42	default n
43	help
44	  Choose this option if you have new Intel hardware and want to enable
45	  the alpha quality i915 driver support for the hardware in this kernel
46	  version. You can also enable the support at runtime using the module
47	  parameter i915.alpha_support=1; this option changes the default for
48	  that module parameter.
49
50	  It is recommended to upgrade to a kernel version with proper support
51	  as soon as it is available. Generally fixes for platforms with alpha
52	  support are not backported to older kernels.
53
54	  If in doubt, say "N".
55
56config DRM_I915_CAPTURE_ERROR
57	bool "Enable capturing GPU state following a hang"
58	depends on DRM_I915
59	default y
60	help
61	  This option enables capturing the GPU state when a hang is detected.
62	  This information is vital for triaging hangs and assists in debugging.
63	  Please report any hang to
64            https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
65	  for triaging.
66
67	  If in doubt, say "Y".

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