From: Eric Anholt Date: Mon, 21 May 2007 17:53:33 +0000 (-0700) Subject: Remove unused intel_batchpool.c. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2b325a9f32e4478d324feaa9fcc3706b8bae4a3b;p=mesa.git Remove unused intel_batchpool.c. This may need to be implemented again, but probably not as a buffer manager (pool). --- diff --git a/src/mesa/drivers/dri/i915tex/intel_batchpool.c b/src/mesa/drivers/dri/i915tex/intel_batchpool.c deleted file mode 100644 index 2503b8a62a1..00000000000 --- a/src/mesa/drivers/dri/i915tex/intel_batchpool.c +++ /dev/null @@ -1,418 +0,0 @@ -/************************************************************************** - * - * Copyright 2006 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.
