From 3dba47e8962ec6ebf7e8825531bd46ab54a84ec6 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 6 Aug 2013 22:27:37 +0200 Subject: [PATCH] tests: add gem_prw_concurrent_blt New testcase to check that pwrite/pread correctly synchronize with oustanding rendering. Just to catch regressions when we change something.
