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

45config DRM_I915_ALPHA_SUPPORT
46	bool "Enable alpha quality support for new Intel hardware by default"
47	depends on DRM_I915

49	  This option is deprecated. Use DRM_I915_FORCE_PROBE option instead.

54	default "*" if DRM_I915_ALPHA_SUPPORT
55	help
56	  This is the default value for the i915.force_probe module
57	  parameter. Using the module parameter overrides this option.
58
59	  Force probe the driver for new Intel graphics devices that are
60	  recognized but not properly supported by this kernel version. It is
61	  recommended to upgrade to a kernel version with proper support as soon
62	  as it is available.
63
64	  Use "" to disable force probe. If in doubt, use this.
65
66	  Use "<pci-id>[,<pci-id>,...]" to force probe the driver for listed
67	  devices. For example, "4500" or "4500,4571".
68
69	  Use "*" to force probe the driver for all known devices.

71config DRM_I915_CAPTURE_ERROR
72	bool "Enable capturing GPU state following a hang"
73	depends on DRM_I915
74	default y
75	help
76	  This option enables capturing the GPU state when a hang is detected.
77	  This information is vital for triaging hangs and assists in debugging.
78	  Please report any hang to
79	    https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
80	  for triaging.
81
82	  If in doubt, say "Y".

87	select ZLIB_DEFLATE
88	default y
89	help
90	  This option selects ZLIB_DEFLATE if it isn't already
91	  selected and causes any error state captured upon a GPU hang
92	  to be compressed using zlib.
93
94	  If in doubt, say "Y".

101	help
102	  This option selects CONFIG_MMU_NOTIFIER if it isn't already
103	  selected to enabled full userptr support.
104
105	  If in doubt, say "Y".

107config DRM_I915_GVT
108	bool "Enable Intel GVT-g graphics virtualization host support"
109	depends on DRM_I915
110	depends on 64BIT
111	default n
112	help
113	  Choose this option if you want to enable Intel GVT-g graphics
114	  virtualization technology host support with integrated graphics.
115	  With GVT-g, it's possible to have one integrated graphics
116	  device shared by multiple VMs under different hypervisors.
117
118	  Note that at least one hypervisor like Xen or KVM is required for
119	  this driver to work, and it only supports newer device from
120	  Broadwell+. For further information and setup guide, you can
121	  visit: http://01.org/igvt-g.
122
123	  Now it's just a stub to support the modifications of i915 for
124	  GVT device model. It requires at least one MPT modules for Xen/KVM
125	  and other components of GVT device model to work. Use it under
126	  you own risk.
127
128	  If in doubt, say "N".
