From 62f50df7b79c273a0eb9bf769eded76933bddc3a Mon Sep 17 00:00:00 2001 From: Bas Nieuwenhuizen Date: Sun, 13 May 2018 22:01:44 +0200 Subject: [PATCH] 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.
