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/radeon_buffer.c | 266 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 266 insertions(+) create mode 100644 linux-core/radeon_buffer.c (limited to 'linux-core/radeon_buffer.c') diff --git a/linux-core/radeon_buffer.c b/linux-core/radeon_buffer.c new file mode 100644 index 00000000..e9ba11d4 --- /dev/null +++ b/linux-core/radeon_buffer.c @@ -0,0 +1,266 @@ +/************************************************************************** + * + * Copyright 2007 Dave Airlie + * 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.
