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

  38 config DRM_I915_PRELIMINARY_HW_SUPPORT

  42         help
  43           Choose this option if you have prerelease Intel hardware and want the
  44           i915 driver to support it by default.  You can enable such support at
  45           runtime with the module option i915.preliminary_hw_support=1; this
  46           option changes the default for that module option.
  47
  48           If in doubt, say "N".

  50 config DRM_I915_CAPTURE_ERROR

  53         default y
  54         help
  55           This option enables capturing the GPU state when a hang is detected.
  56           This information is vital for triaging hangs and assists in debugging.
  57           Please report any hang to
  58             https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
  59           for triaging.

  66         select ZLIB_DEFLATE
  67         default y
  68         help
  69           This option selects ZLIB_DEFLATE if it isn't already
  70           selected and causes any error state captured upon a GPU hang
  71           to be compressed using zlib.
  72
  73           If in doubt, say "Y".

  80         help
  81           This option selects CONFIG_MMU_NOTIFIER if it isn't already
  82           selected to enabled full userptr support.
  83
  84           If in doubt, say "Y".

  89         default n
  90         help
  91           Choose this option if you want to enable Intel GVT-g graphics
  92           virtualization technology host support with integrated graphics.
  93           With GVT-g, it's possible to have one integrated graphics
  94           device shared by multiple VMs under different hypervisors.
  95
  96           Note that at least one hypervisor like Xen or KVM is required for
  97           this driver to work, and it only supports newer device from
  98           Broadwell+. For further information and setup guide, you can
  99           visit: http://01.org/igvt-g.
 100
 101           Now it's just a stub to support the modifications of i915 for
 102           GVT device model. It requires at least one MPT modules for Xen/KVM
 103           and other components of GVT device model to work. Use it under
 104           you own risk.
 105
 106           If in doubt, say "N".
