 22           Choose this option if you have a system that has "Intel Graphics
 23           Media Accelerator" or "HD Graphics" integrated graphics,
 24           including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
 25           G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
 26           Core i5, Core i7 as well as Atom CPUs with integrated graphics.
 27           If M is selected, the module will be called i915.  AGP support
 28           is required for this driver to work. This driver is used by
 29           the Intel driver in X.org 6.8 and XFree86 4.4 and above. It
 30           replaces the older i830 module that supported a subset of the
 31           hardware in older X.org releases.
 32 
 33           Note that the older i810/i815 chipsets require the use of the
 34           i810 driver instead, and the Atom z5xx series has an entirely
 35           different implementation.
 36 
 37 config DRM_I915_PRELIMINARY_HW_SUPPORT
 38         bool "Enable preliminary support for prerelease Intel hardware by default"
 39         depends on DRM_I915
 40         default n
 41         help
 42           Choose this option if you have prerelease Intel hardware and want the
 43           i915 driver to support it by default.  You can enable such support at
 44           runtime with the module option i915.preliminary_hw_support=1; this
 45           option changes the default for that module option.
 46 
 47           If in doubt, say "N".

 49 config DRM_I915_USERPTR
 50         bool "Always enable userptr support"
 51         depends on DRM_I915
 52         select MMU_NOTIFIER
 53         default y
 54         help
 55           This option selects CONFIG_MMU_NOTIFIER if it isn't already
 56           selected to enabled full userptr support.
 57 
 58           If in doubt, say "Y".
 59 
 60 config DRM_I915_GVT
 61         bool "Enable Intel GVT-g graphics virtualization host support"
 62         depends on DRM_I915
 63         default n
 64         help
 65           Choose this option if you want to enable Intel GVT-g graphics
 66           virtualization technology host support with integrated graphics.
 67           With GVT-g, it's possible to have one integrated graphics
 68           device shared by multiple VMs under different hypervisors.
 69 
 70           Note that at least one hypervisor like Xen or KVM is required for
 71           this driver to work, and it only supports newer device from
 72           Broadwell+. For further information and setup guide, you can
 73           visit: http://01.org/igvt-g.
 74 
 75           Now it's just a stub to support the modifications of i915 for
 76           GVT device model. It requires at least one MPT modules for Xen/KVM
 77           and other components of GVT device model to work. Use it under
 78           you own risk.
 79 
 80           If in doubt, say "N".
