From 3f8bcb0d998820594ea288e4607462fa4479859f Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 3 Dec 2010 16:50:19 -0800 Subject: i965: Align gen6 push constant size to dispatch width. The FS backend is fine with register level granularity. But for the brw_wm_emit.c backend, it expects pairs of regs to be used for the constants, because the whole world is pairs of regs. If an odd number got used, we went looking for interpolation in the wrong place. --- src/mesa/drivers/dri/i965/gen6_wm_state.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/mesa/drivers/dri/i965/gen6_wm_state.c b/src/mesa/drivers/dri/i965/gen6_wm_state.c index 0d839de10dd..8968caef510 100644 --- a/src/mesa/drivers/dri/i965/gen6_wm_state.c +++ b/src/mesa/drivers/dri/i965/gen6_wm_state.c @@ -105,7 +105,8 @@ upload_wm_state(struct brw_context *brw) (5 - 2)); OUT_RELOC(brw->wm.push_const_bo, I915_GEM_DOMAIN_RENDER, 0, /* XXX: bad domain */ - ALIGN(brw->wm.prog_data->nr_params, 8) / 8 - 1); + ALIGN(brw->wm.prog_data->nr_params, + brw->wm.prog_data->dispatch_width) / 8 - 1); OUT_BATCH(0); OUT_BATCH(0); OUT_BATCH(0); -- cgit v1.2.3
