These patch series removes the dependency of i915/gvt hypervisor backends on the driver internals of the i915 driver. Instead, we add a small public API that hypervisor backends can use.
This enables out-of-tree hypervisor backends for the Intel graphics virtualization and simplifies development. At the same time, it creates at least a bit of a barrier to including more i915 internals into kvmgt, which is nice in itself.
The first two patches are pretty much general cleanup and could be merged without the rest.
Any feedback is welcome.
