From 07e99d9fb491d625034fc21e3f2d631acce341bf Mon Sep 17 00:00:00 2001 From: Thomas White Date: Sun, 2 Aug 2009 22:33:34 +0100 Subject: Add GEM mmap() and KMS tests 'gdrm-gem-mmap' creates a GEM object, mmap()s it, and tests access. 'gdrm-kms-addfb' creates a GEM object, switches the active framebuffer to use it, and writes random colours to it via memory mapped access. --- drmtest.c | 86 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 86 insertions(+) create mode 100644 drmtest.c (limited to 'drmtest.c') diff --git a/drmtest.c b/drmtest.c new file mode 100644 index 0000000..d053865 --- /dev/null +++ b/drmtest.c @@ -0,0 +1,86 @@ +/* + * Copyright © 2007 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.
