vmw_resource_unreserve - unreserve resources previously reserved for command submission.
: list of resources to unreserve.
Currently only surfaces are considered, and unreserving a surface means putting it back on the device's surface lru list, so that it can be evicted if necessary. This function traverses the resource list and checks whether resources are surfaces, and in that case puts them back on the device's surface LRU list.

vmw_surface_do_validate - make a surface available to the device.
: Pointer to a device private struct. : Pointer to a struct vmw_surface.
If the surface doesn't have a hw id, allocate one, and optionally DMA the backed up surface contents to the device.
Returns -EBUSY if there wasn't sufficient device resources to complete the validation. Retry after freeing up resources.
May return other errors if the kernel is out of guest resources.

vmw_surface_evict - Evict a hw surface.
: Pointer to a device private struct. : Pointer to a struct vmw_surface
DMA the contents of a hw surface to a backup guest buffer object, and destroy the hw surface, releasing its id.

vmw_surface_validate - make a surface available to the device, evicting other surfaces if needed.
: Pointer to a device private struct. : Pointer to a struct vmw_surface.
Try to validate a surface and if it fails due to limited device resources, repeatedly try to evict other surfaces until the request can be acommodated.
May return errors if out of resources.
