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.

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

67	  This option enables capturing the GPU state when a hang is detected.
68	  This information is vital for triaging hangs and assists in debugging.
69	  Please report any hang to
70            https://bugs.freedesktop.org/enter_bug.cgi?product=DRI

80	help
81	  This option selects ZLIB_DEFLATE if it isn't already
82	  selected and causes any error state captured upon a GPU hang
83	  to be compressed using zlib.

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