From 818db3848bfaa002d0e7cf6b9b615a31eb82ba25 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 22 Jul 2011 10:56:10 -0700 Subject: [PATCH] i965: Fix many of the trivial WebGL demos that broke due to IB optimization. The index buffer state emit only occurred if there was an IB in place and we were in either a new batch or a new IB state. But because we only flagged new IB state if IB state changed from the last IB state we calculated, we could simply never emit IB state after batchbuffer wraps if the first draw didn't use the IB and we didn't actually change the IB. Fixes piglit glx-multi-context-ib-1. --- src/mesa/drivers/dri/i965/brw_vtbl.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/mesa/drivers/dri/i965/brw_vtbl.c b/src/mesa/drivers/dri/i965/brw_vtbl.c index 55dbd4f..40360b2 100644 --- a/src/mesa/drivers/dri/i965/brw_vtbl.c +++ b/src/mesa/drivers/dri/i965/brw_vtbl.c @@ -213,6 +213,7 @@ static void brw_new_batch( struct intel_context *intel ) brw->state_batch_count = 0; brw->vb.nr_current_buffers = 0; + brw->ib.type = -1; /* Mark that the current program cache BO has been used by the GPU. * It will be reallocated if we need to put new programs in for the -- 2.7.4
