Subject: v3dv: use wait stage for wait semaphores to decide about binning syncs
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=184a48197f08372555f0cc408def63bfdb70adee;p=platform%2Fupstream%2Fmesa.git

v3dv: use wait stage for wait semaphores to decide about binning syncs

If the wait stage for a semaphore doesn't involve geometry stages we
don't need a binning sync.
