From d1b34baf9b9c977d2bcd612aa8ea7256f2143ad8 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 25 Feb 2013 13:56:01 -0800 Subject: [PATCH] i965: Write TIMESTAMP query values into the first buffer element. For timestamp queries, we just write a single value to a BO. The natural place to write that is element 0, so we should do that. Previously, we wrote it into element 1 (the second slot) leaving element 0 filled with garbage.
