From 78de69713d742645c1c4347a06afca5b38f97184 Mon Sep 17 00:00:00 2001 From: Jerome Glisse Date: Thu, 8 Apr 2010 17:50:34 +0200 Subject: drm/radeon: add new cs command stream dumping facilities Dump command stream + associated bo into a binary file which follow a similar design as json file. It allows to intercept a command stream and replay it in a standalone program (see radeondb tools). --- radeon/bof.c | 477 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 477 insertions(+) create mode 100644 radeon/bof.c (limited to 'radeon/bof.c') diff --git a/radeon/bof.c b/radeon/bof.c new file mode 100644 index 00000000..0598cc6b --- /dev/null +++ b/radeon/bof.c @@ -0,0 +1,477 @@ +/* + * Copyright 2010 Jerome Glisse + * + * 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.
