From: Jason Ekstrand Date: Sat, 17 Oct 2015 03:01:45 +0000 (-0700) Subject: anv: Add facilities for dumping an image to a file X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7010fe61c8c72ce9bc8df98d730d99652333d460;p=mesa.git anv: Add facilities for dumping an image to a file The ability to dump an arbitrary miplevel or array slice of an anv_image to a file is very useful for debugging. Nothing inside of the driver calls this right now, but it's very useful to call from GDB. --- diff --git a/src/vulkan/Makefile.am b/src/vulkan/Makefile.am index aeed78ae840..985864a87fe 100644 --- a/src/vulkan/Makefile.am +++ b/src/vulkan/Makefile.am @@ -63,6 +63,7 @@ VULKAN_SOURCES = \ anv_batch_chain.c \ anv_compiler.cpp \ anv_device.c \ + anv_dump.c \ anv_entrypoints.c \ anv_entrypoints.h \ anv_formats.c \ diff --git a/src/vulkan/anv_dump.c b/src/vulkan/anv_dump.c new file mode 100644 index 00000000000..3878941896c --- /dev/null +++ b/src/vulkan/anv_dump.c @@ -0,0 +1,210 @@ +/* + * Copyright © 2015 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.
