Subject: v3d: Stop clearing the OQ state at the end of the job.
X-Git-Tag: upstream/19.0.0~2513
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0b8007b52316f76c76ca05846c858055f0cc9e38;p=platform%2Fupstream%2Fmesa.git

v3d: Stop clearing the OQ state at the end of the job.

Ever since we added OQ support, we've been clearing OQ state at the start
of the job anyway.  We're intentionally breaking old-and-new-driver-mix
systems, because we need to stop using the unvalidated FLUSH_ALL_STATE.
