  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,
  30           G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
  31           Core i5, Core i7 as well as Atom CPUs with integrated graphics.
  32
  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.

  46         default n
  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".

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

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

  92           selected to enabled full userptr support.
  93

 100         default n
 101         help
 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.
 116
 117           If in doubt, say "N".
