KVMGT is the MPT implementation based on VFIO/KVM. It provides a kvmgt_mpt ops to gvt for vGPU access mediation, e.g. to mediate and emulate the MMIO accesses, to inject interrupts to vGPU user, to intercept the GTT writing and replace it with DMA-able address, to write-protect guest PPGTT table for shadowing synchronization, etc. This patch provides the MPT implementation for GVT, not yet functional due to theabsence of mdev. It's built as kvmgt.ko, depends on vfio.ko, kvm.ko and mdev.ko, and being required by i915.ko. To not introduce hard dependency in i915.ko, we used indirect symbol reference. But that means users have to include kvmgt.ko into init ramdisk if their i915.ko is included.
