From 741bf7064c467df725c14cc0b3b8b50436f9ee09 Mon Sep 17 00:00:00 2001 From: Arkadiusz Hiler Date: Thu, 18 Oct 2018 14:06:42 +0300 Subject: tests: Introduce i915 directory We can already move all the tests with distinct prefixes: gem_, gen3_ and i915_. pm_ and drv_ tests will follow in batches, so we can do the adjustments in the reporting/filtering layer of the CI system. v2: Fix test-list.txt generation with meson v3: Fix docs build (Petri) Cc: Chris Wilson Cc: Petri Latvala Cc: Martin Peres Signed-off-by: Arkadiusz Hiler Reviewed-by: Petri Latvala Tested-by: Petri Latvala Acked-by: Daniel Vetter Acked-by: Chris Wilson --- tests/i915/gem_mmap.c | 186 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 186 insertions(+) create mode 100644 tests/i915/gem_mmap.c (limited to 'tests/i915/gem_mmap.c') diff --git a/tests/i915/gem_mmap.c b/tests/i915/gem_mmap.c new file mode 100644 index 00000000..0ed15878 --- /dev/null +++ b/tests/i915/gem_mmap.c @@ -0,0 +1,186 @@ +/* + * Copyright © 2008 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.
