  25           Choose this option if you have a system that has "Intel Graphics
  26           Media Accelerator" or "HD Graphics" integrated graphics,
  27           including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
  28           G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
  29           Core i5, Core i7 as well as Atom CPUs with integrated graphics.

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

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

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

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

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