To get the p2pdma_distance, this create a new privcmd ioctl to calculate

So this series introduce an implementation of virtgpu device_attach
callback to get p2pdma_distance. And also adds a new virtgpu command to
pass PCI notations from guest to host and a new xen privcmd to get physical
p2pdma_distance according to the PCI notations in host.

implement virtgpu specific map/unmap/attach callbacks to support both of
shmem objects and vram objects.
Changes from v1 to v2:
-Reimplement virtgpu_gem_device_attach()
-Remove calling drm dma-buf funcs in virtgpu callbacks and reimplement virtgpu
specific dma-buf callbacks.

Hi all,
Sorry to late reply. This is v2 of the implementation of
resource_query_layout. This adds a new ioctl to let guest query information
of host resource, which is originally from Daniel Stone. We add some
changes to support query the correct stride of host resource before it's
created, which
Modify RESOURCE_GET_LAYOUT ioctl to handle the use case that query
correct stride for guest linear resource before it is created.

From: Daniel Stone
This ioctl allows the guest to discover how the guest actually allocated
the underlying buffer, which allows buffers to be used for GL<->Vulkan
interop and through standard window systems. It's also a step towards
properly supporting modifiers in the guest.

Remove stride and layer_stride check in virtio-gpu so that virgl can
send transfer data command with non zero stride to sync up data from
guest to host for dGPU prime on VM.
