e473405783 drm/i915/gvt: vGPU workload scheduler
This patch introduces the vGPU workload scheduler routines.

GVT workload scheduler is responsible for picking and executing GVT workload
from current scheduled vGPU. Before the workload is submitted to host i915,
the guest execlist context will be shadowed in the host GVT shadow context.
the instructions in guest ring buffer will be copied into GVT shadow ring
buffer. Then GVT-g workload scheduler will scan the instructions in guest
ring buffer and submit it to host i915.

28c4c6ca7f drm/i915/gvt: vGPU workload submission
This patch introduces the vGPU workload submission logics.

Under virtualization environment, guest will submit workload through
virtual execlist submit port. The submitted workload load will be wrapped
into an gvt workload which will be picked by GVT workload scheduler and
executed on host i915 later.

04d348ae3f drm/i915/gvt: vGPU display virtualization
This patch introduces the GVT-g display virtualization.

It consists a collection of display MMIO handlers, like power well register
handler, pipe register handler, plane register handler, which will emulate
all display MMIOs behavior to support virtual mode setting sequence for
guest.

e39c5add32 drm/i915/gvt: vGPU MMIO virtualization
This patch introduces the generic vGPU MMIO emulation intercept
framework.  The MPT modules will request GVT-g core logic to
emulate MMIO read/write through IO emulation operations
callback when hypervisor trapped a guest GTTMMIO read/write.

12d14cc43b drm/i915/gvt: Introduce a framework for tracking HW registers.
This patch introduces a framework for tracking HW registers on different
GEN platforms.

Accesses to GEN HW registers from VMs will be trapped by hypervisor. It
will forward these emulation requests to GVT-g device model, which
requires this framework to search for related register descriptions.

Each MMIO entry in this framework describes a GEN HW registers, e.g.
offset, length, whether it contains RO bits, whether it can be accessed by
LRIs...and also emulation handlers for emulating register reading and
writing.

- Use i915 MMIO register definition & statement.(Joonas)
