The mediated bus driver is responsible for adding mediated devices to the VFIO
group when devices are bound to the driver and removing mediated devices from
the VFIO when devices are unbound from the driver.
Physical Device Driver Interface
--------------------------------
The physical device driver interface provides the mdev_parent_ops[3] structure
to define the APIs to manage work in the mediated core driver that is related
to the physical device.
The structures in the mdev_parent_ops structure are as follows:
* dev_attr_groups: attributes of the parent device
* mdev_attr_groups: attributes of the mediated device
* supported_config: attributes to define supported configurations
* device_driver: device driver to bind for mediated device instances
The mdev_parent_ops also still has various functions pointers. Theses exist
for historical reasons only and shall not be used for new drivers.
The mediated bus driver's probe function should create a vfio_device on top of
the mdev_device and connect it to an appropriate implementation of
vfio_device_ops.
When a driver wants to add the GUID creation sysfs to an existing device it has
probe'd to then it should call::
extern int mdev_register_device(struct device *dev,
const struct mdev_parent_ops *ops);
struct mdev_driver *mdev_driver);
This will provide the 'mdev_supported_types/XX/create' files which can then be
used to trigger the creation of a mdev_device. The created mdev_device will be

Choose this option if you want to enable Intel GVT-g graphics

With GVT-g, it's possible to have one integrated graphics
device shared by multiple VMs under different hypervisors.

this driver to work, and it only supports newer device from
Broadwell+. For further information and setup guide, you can

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.
