From a37835c8eda017f0c955e0927e7418e7f3ba3b73 Mon Sep 17 00:00:00 2001 From: Martin Andersson Date: Sat, 2 Feb 2013 17:55:07 +0100 Subject: [PATCH] winsys/radeon: fix bo with virtual address referencing mismatch If the same context try to flink and open the object, use the same bo struct instead of opening a new gem handle for the object. This way we avoid avoid having 2 different handle pointing to the same kernel object which can latter lead to trouble with virtual address.
