From df9871064e8b564d9ae2e56d561b64434fd004af Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sat, 26 Jul 2008 08:56:23 +1000 Subject: radeon: add initial atombios modesetting and GEM -> TTM translation layer. This is an initial import of the atom bios parser with modesetting support for r500 hw using atombios. It also includes a simple memory manager layer that translates a radeon GEM style interface onto TTM internally. So far this memory manager has only been used for pinned object allocation for the DDX to test modesetting. --- linux-core/atom-bits.h | 48 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 linux-core/atom-bits.h (limited to 'linux-core/atom-bits.h') diff --git a/linux-core/atom-bits.h b/linux-core/atom-bits.h new file mode 100644 index 00000000..f94d2e27 --- /dev/null +++ b/linux-core/atom-bits.h @@ -0,0 +1,48 @@ +/* + * Copyright 2008 Advanced Micro Devices, Inc. + * + * 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 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.
