A lot of PCI IDs were missing and there were some problems with the
configuration and firmware selection for devices on the 9000 series.
Fix the firmware selection by adding files for the B-steps; add
configuration for some integrated devices; and add a bunch of PCI IDs
(mostly for integrated devices) that were missing from the driver's
list.
Without this patch, a lot of devices will not be recognized or will
try to load the wrong firmware file.

Previously the performance is improved through the workload auditing
and shadowing ahead of vGPU scheduling, however, there is the case that
more requests are allocated in submit_context before the previous request
is added, the timeline will hold its seqno which is later.
This patch is to move the request alloc to dispatch_workload function,
where is the same place as request is added.
It will fix the issue of kernel BUG for (timeline->seqno != request->fence.seqno)
check when add_request.

Currently every vgpu share a common gvt opregion memory, but
it is freed at vgpu destroy, then the later vgpu doesn't have
opregion memory once the first vgpu is destroyed. This cause
guest function failure like reboot, second or later boot.

vgpu, so this memory could be freed at vgpu destroy.

Our vGPU doesn't have a device ROM, we need follow the PCI spec to
report this info to drivers. Otherwise, we would see below errors.
Inspecting possible rom at 0xfe049000 (vd=8086:1912 bdf=00:10.0)

Device option ROM contents are probably invalid (check dmesg).
Skip option ROM probe with rombar=0, or load from file with romfile=No option rom signature (got 4860)
I will also send a improvement patch to PCI subsystem related to PCI ROM.
But no idea to omit below error, since no pattern to detect vbios shadow

The engine provides a mirror of the CSB and CSB write pointer in the HWSP.
Read these status from virtual HWSP in VM can reduce CPU utilization while
applications have much more short GPU workloads. Here we update the
corresponding data in virtual HWSP as it in virtual MMIO.
Before read these status from HWSP in GVT-g VM, please ensure the host
support it by checking the BIT(3) of caps in PVINFO.
Virtual HWSP only support GEN8+ platform, since the HWSP MMIO may change
follow the platform update, please add the corresponding MMIO emulation
when enable new platforms in GVT-g.
v3 : Add address audit in HWSP address update.
v4 :
Separate this patch with enalbe virtual HWSP in VM.
Use intel_gvt_render_mmio_to_ring_id() to determine ring_id by offset.
v5 : Remove unnessary check about Gen8, GVT-g only support Gen8+.

Theoretically, the largest bulk of commands in the ring buffer of an
engine might be the first submission, which usually contains a lot
of commands to initialize the HW. After removing the initial allocation
of the ring scan buffer and let krealloc() do everything we need, we
still have a big chance to get the buffer of suitable size in the first
submission.
