Author: Bas Nieuwenhuizen <[email protected]> Date: Sun May 13 22:01:44 2018 +0200 radv: Fix multiview queries. This moves the extra queries to after the main query ended, instead of doing it after the begin and hence doing nesting. We also emit only (view count - 1) extra queries, as the main query is already there for the first view. This fixes the CTS occasionally getting stuck in dEQP-VK.multiview.queries* waiting on results. Fixes: 32b4f3c38dc "radv/query: handle multiview queries properly.
