From 431a2f99bc9d4ab567c1feaac9360c09c1dcdfde Mon Sep 17 00:00:00 2001 From: Keith Whitwell Date: Wed, 10 Mar 2010 10:32:16 +0000 Subject: target-helpers: helper for injecting common debug layers Add a helper gallium_wrap_screen() for injecting the commonly used extra layers into a gallium stack. Currently that's just the trace module and identity layer, but there could be more in the future, eg. a validation layer. --- src/gallium/auxiliary/target-helpers/wrap_screen.c | 65 ++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 src/gallium/auxiliary/target-helpers/wrap_screen.c (limited to 'src/gallium/auxiliary/target-helpers/wrap_screen.c') diff --git a/src/gallium/auxiliary/target-helpers/wrap_screen.c b/src/gallium/auxiliary/target-helpers/wrap_screen.c new file mode 100644 index 0000000000..5fe3013938 --- /dev/null +++ b/src/gallium/auxiliary/target-helpers/wrap_screen.c @@ -0,0 +1,65 @@ +/************************************************************************** + * + * Copyright 2007 Tungsten Graphics, Inc., Bismarck, ND., USA + * 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 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 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.
