help
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.
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.
If "M" is selected, the module will be called i915.
config DRM_I915_ALPHA_SUPPORT
bool "Enable alpha quality support for new Intel hardware by default"
depends on DRM_I915
default n
help
Choose this option if you have new Intel hardware and want to enable
the alpha quality i915 driver support for the hardware in this kernel
version. You can also enable the support at runtime using the module
parameter i915.alpha_support=1; this option changes the default for
that module parameter.
It is recommended to upgrade to a kernel version with proper support
as soon as it is available. Generally fixes for platforms with alpha
support are not backported to older kernels.
If in doubt, say "N".
config DRM_I915_CAPTURE_ERROR
bool "Enable capturing GPU state following a hang"
depends on DRM_I915
default y
help
This option enables capturing the GPU state when a hang is detected.
This information is vital for triaging hangs and assists in debugging.
Please report any hang to
https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
for triaging.
If in doubt, say "Y".
config DRM_I915_COMPRESS_ERROR
bool "Compress GPU error state"
depends on DRM_I915_CAPTURE_ERROR
select ZLIB_DEFLATE
default y
help
This option selects ZLIB_DEFLATE if it isn't already
selected and causes any error state captured upon a GPU hang
to be compressed using zlib.
If in doubt, say "Y".
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
depends on 64BIT
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".

depends on VFIO_MDEV && VFIO_MDEV_DEVICE
default n
help
Choose this option if you want to enable KVMGT support for
Intel GVT-g.
