st/va: force to flush the last p frame in idr period
During dual instance encoding submission, if the second encode task and first encode task have no reference dependency, e.g. p following with idr-frame, there is a chance the second task will use for its reconstructed picture buffer the same buffer used by first task for its reference/reconstructed picture. In this case, buffer corruption may occur depending on encoding speed. Fix is to force flush these two tasks separately to avoid race condition Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=98005 Signed-off-by: Boyuan Zhang <[email protected]> Reviewed-by: Christian König <[email protected]>
