From 29a6307e12e132104ce42ad3b83e377ca34880a7 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 31 Oct 2012 13:36:16 -0700 Subject: [PATCH] i965: Set dirty state for brw_draw_upload.c when num_instances changes. Otherwise, if we had a set of prims passed in with a num_instances varying between them, we wouldn't upload enough (or too much!) from user vertex arrays.
