959ea7115f vmm: implement AccessPlatform for SEV-SNP proxy struct 
Implement AccessPlatform for SEV-SNP guest to access
restricted page using IO. VMM calls MSHV api to get access
of the pages, MSHV requests guest to release the access.

5f18ac3bc0 devices: Add pvmemcontrol device 
Pvmemcontrol provides a way for the guest to control its physical memory
properties, and enables optimizations and security features. For
example, the guest can provide information to the host where parts of a
hugepage may be unbacked, or sensitive data may not be swapped out, etc.

Pvmemcontrol allows guests to manipulate its gPTE entries in the SLAT,
and also some other properties of the memory map the back's host memory.
This is achieved by using the KVM_CAP_SYNC_MMU capability. When this
capability is available, the changes in the backing of the memory region
on the host are automatically reflected into the guest. For example, an
mmap() or madvise() that affects the region will be made visible
immediately.

There are two components of the implementation: the guest Linux driver
and Virtual Machine Monitor (VMM) device. A guest-allocated shared
buffer is negotiated per-cpu through a few PCI MMIO registers, the VMM
device assigns a unique command for each per-cpu buffer. The guest
writes its pvmemcontrol request in the per-cpu buffer, then writes the
corresponding command into the command register, calling into the VMM
device to perform the pvmemcontrol request.

The synchronous per-cpu shared buffer approach avoids the kick and busy
waiting that the guest would have to do with virtio virtqueue transport.

The Cloud Hypervisor component can be enabled with --pvmemcontrol.

954f3dd057 vm-device: generalize BusDevice to use a shared reference 
BusDevice trait functions currently holds a mutable reference to self,
and exclusive access is guaranteed by taking a Mutex when dispatched by
the Bus object. However, this prevents individual devices from serving
accesses that do not require an mutable reference or is better served
with different synchronization primitives. We switch Bus to dispatch via
BusDeviceSync, which holds a shared reference, and delegate locking to
the BusDeviceSync trait implementation for Mutex<BusDevice>.

Other changes are made to make use of the dyn BusDeviceSync
trait object.

indicate that there were no error while handling the GHCB exit.
Recently, new Linux guests got stricter with checking the value of

this behavior by clearing out SW_EXIT_INFO1 in case of no error.

a2438700e4 virtio-devices: support event idx for virtio-blk 
Support event idx feature for virtio-blk device.
This feature could improve disk IO performance by suppressing
notifications from guest to host and interrupts from host to
guest, which has been already supported in virtio-net and
vhost-user devices.

To achieve this, virtqueue's event-idx-related API is
leveraged for avail_event field update and needs_notification
check.

Fixes: #6580
