Choose this option if you have a system that has "Intel Graphics
Media Accelerator" or "HD Graphics" integrated graphics,
including 830M, 845G, 852GM, 855GM, 865G, 915G, 945G, 965G,
G35, G41, G43, G45 chipsets and Celeron, Pentium, Core i3,
Core i5, Core i7 as well as Atom CPUs with integrated graphics.
If M is selected, the module will be called i915. AGP support
is required for this driver to work. This driver is used by
the Intel driver in X.org 6.8 and XFree86 4.4 and above. It
replaces the older i830 module that supported a subset of the
hardware in older X.org releases.
Note that the older i810/i815 chipsets require the use of the
i810 driver instead, and the Atom z5xx series has an entirely
different implementation.
config DRM_I915_PRELIMINARY_HW_SUPPORT
bool "Enable preliminary support for prerelease Intel hardware by default"
depends on DRM_I915
default n
help
Choose this option if you have prerelease Intel hardware and want the
i915 driver to support it by default. You can enable such support at
runtime with the module option i915.preliminary_hw_support=1; this
option changes the default for that module option.
If in doubt, say "N".
config DRM_I915_USERPTR
bool "Always enable userptr support"
depends on DRM_I915
select MMU_NOTIFIER
default y
help
This option selects CONFIG_MMU_NOTIFIER if it isn't already
selected to enabled full userptr support.
If in doubt, say "Y".
config DRM_I915_GVT
bool "Enable Intel GVT-g graphics virtualization host support"
depends on DRM_I915
default n
help
Choose this option if you want to enable Intel GVT-g graphics
virtualization technology host support with integrated graphics.
With GVT-g, it's possible to have one integrated graphics
device shared by multiple VMs under different hypervisors.
Note that at least one hypervisor like Xen or KVM is required for
this driver to work, and it only supports newer device from
Broadwell+. For further information and setup guide, you can
visit: http://01.org/igvt-g.
Now it's just a stub to support the modifications of i915 for
GVT device model. It requires at least one MPT modules for Xen/KVM
and other components of GVT device model to work. Use it under
you own risk.
If in doubt, say "N".
