drm/xe/oa: Add syncs support to OA config ioctl
[ Upstream commit 9920c8b88c5cf2e44f4ff508dd3c0c96e4364db0 ]
In addition to stream open, add xe_sync support to the OA config ioctl,
where it is even more useful. This allows e.g. Mesa to replay a workload
repeatedly on the GPU, each time with a different OA configuration, while
precisely controlling (at batch buffer granularity) the workload segment
for which a particular OA configuration is active, without introducing
stalls in the userspace pipeline.
v2: Emit OA config even when config id is same as previous, to ensure
consistent sync behavior (Jose)
