From 34ca0fce228224121d1a3b111c38325e731bace3 Mon Sep 17 00:00:00 2001 From: Timothy Arceri Date: Thu, 14 Apr 2016 11:08:32 +1000 Subject: glsl: add initial implementation of shader cache MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This uses disk_cache.c to write out a serialization of various state that's required in order to successfully load and use a binary written out by a drivers backend, this state is referred to as "metadata" throughout the implementation. This initial version is intended to work with all stages beside compute. This patch is based on the initial work done by Carl. V2: extend the file's doxygen comment to cover some of the design decisions. V3: - skip cache for fixed function shaders - add int64 support - fix glsl IR program parameter caching/restore and cache the parameter values which are used by gallium backends. - use new link status enum V4: - add compute program support Reviewed-by: Nicolai Hähnle --- src/compiler/glsl/shader_cache.h | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 src/compiler/glsl/shader_cache.h (limited to 'src/compiler/glsl/shader_cache.h') diff --git a/src/compiler/glsl/shader_cache.h b/src/compiler/glsl/shader_cache.h new file mode 100644 index 00000000000..8bd0a3ce282 --- /dev/null +++ b/src/compiler/glsl/shader_cache.h @@ -0,0 +1,38 @@ +/* + * Copyright © 2014 Intel Corporation + * + * 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, sublicense, + * 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 NONINFRINGEMENT.
