From 1936e4bdfd776f78f9fe44f77ce66066fd166360 Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Mon, 17 Mar 2008 15:45:52 -0700 Subject: cell: Initial code-gen for alpha / stencil / depth testing Alpha test is currently broken because all per-fragment testing occurs before alpha is calculated. Stencil test is currently broken because the Z-clear code asserts if there is a stencil buffer. --- .../drivers/cell/ppu/cell_state_per_fragment.h | 35 ++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 src/gallium/drivers/cell/ppu/cell_state_per_fragment.h (limited to 'src/gallium/drivers/cell/ppu/cell_state_per_fragment.h') diff --git a/src/gallium/drivers/cell/ppu/cell_state_per_fragment.h b/src/gallium/drivers/cell/ppu/cell_state_per_fragment.h new file mode 100644 index 0000000000..541c3b3be0 --- /dev/null +++ b/src/gallium/drivers/cell/ppu/cell_state_per_fragment.h @@ -0,0 +1,35 @@ +/* + * (C) Copyright IBM Corporation 2008 + * All Rights Reserved. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * on the rights to use, copy, modify, merge, publish, distribute, sub + * license, and/or sell copies of the Software, and to permit persons to whom + * the Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT.
