[RFC PATCH i-g-t 0/2] Xe driver watch-queue implementation and example

["Thomas Hellström" <thomas.hellstrom@linux.intel.com>]

This series aims to provide an example how to use the xe driver watch-queue
interface. The interface provides a means for user-space render clients to get
asynchronous notifications with metadata attached.

The primary use-case would be the LR mode rebind worker running out of
memory. Currently the VM gets killed, but it should be possible to
recover, unbind buffer objects and restart.
