From: Matthew Auld <matthew.auld@xxxxxxxxx> commit 1008368e1c7e36bdec01b3cce1e76606dc3ad46f upstream. The queue width will determine the number of batch buffer emitted into the ring. In the case of xe_bb_create_job() we pass exactly one batch address, therefore add an assert for the width to make sure we don't go out of bounds. While here also convert to the helper to determine if the queue is migration based.
