From 781263486f4b828ab2b787d307f32ac65286f05a Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Fri, 7 Jul 2017 10:57:09 -0700 Subject: [PATCH] anv: Stop setting domains to RENDER on EXEC_OBJECT_WRITE The reason we were doing this was to ensure that the kernel did the appropriate cross-ring synchronization and flushing. However, the kernel only looks at EXEC_OBJECT_WRITE to determine whether or not to insert a fence. It only cares about the domain for determining whether or not it needs to clflush the BO before using it for scanout but the domain automatically gets set to RENDER internally by the kernel if EXEC_OBJECT_WRITE is set.
