From 8bdac874e667179bd2682f0111cd7db58b858e5b Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 13 Oct 2016 12:38:49 +1000 Subject: radv/wsi: fix app that acquire multiple images up front dota2 does multiple acquires followed by multiple queues, this bug manifested itself as a hang in the xshmfence code randomly when dota2 was doing it's menus. It also occured when running dota2 under phoronix-test-suite. The fix is once the image is acquired to mark it busy then so nobody else can acquire. We have to trust vulkan apps that they will eventually submit it.
