 27	  Choose this option if you have a system that has "Intel Graphics
 28	  Media Accelerator" or "HD Graphics" integrated graphics,
 29	  including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,

 33	  This driver is used by the Intel driver in X.org 6.8 and
 34	  XFree86 4.4 and above. It replaces the older i830 module that
 35	  supported a subset of the hardware in older X.org releases.
 36
 37	  Note that the older i810/i815 chipsets require the use of the
 38	  i810 driver instead, and the Atom z5xx series has an entirely
 39	  different implementation.
 40
 41	  If "M" is selected, the module will be called i915.

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

 65	  This option enables capturing the GPU state when a hang is detected.

 67	  Please report any hang to
 68            https://bugs.freedesktop.org/enter_bug.cgi?product=DRI

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