KVMGT leverages vfio/mdev to mediate device accesses from guest, this patch adds the vfio/mdev support, thereby completes the functionality. An intel_vgpu is presented as a mdev device, and full userspace API compatibility with vfio-pci is kept. An intel_vgpu_ops is provided to mdev framework, methods get called to create/remove a vgpu, to open/close it, and to access it.

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.

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".

This option enables capturing the GPU state when a hang is detected.

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".
