From: Ankitprasad Sharma <ankitprasad.r.sharma@xxxxxxxxx> This test validates the two parameters (size and flags) GEM_CREATE ioctl. v2: Added IGT_TEST_DESCRIPTION (Thomas Wood) v3: Removed use of hard coded values, updated comments (Tvrtko) v4: Removed over-use of macros, updated with multiples of PAGE_SIZE (Tvrtko) Signed-off-by: Ankitprasad Sharma <ankitprasad.r.sharma at intel.com> --- tests/Makefile.sources | 1 + tests/gem_create.c | 166 +++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 167 insertions(+) create mode 100644 tests/gem_create.c diff --git a/tests/Makefile.sources b/tests/Makefile.sources index 324cbb5..f5790df 100644 --- a/tests/Makefile.sources +++ b/tests/Makefile.sources @@ -15,6 +15,7 @@ TESTS_progs_M = \ gem_close_race \ gem_concurrent_blit \ gem_concurrent_all \ + gem_create \ gem_cs_tlb \ gem_ctx_param_basic \ gem_ctx_bad_exec \ diff --git a/tests/gem_create.c b/tests/gem_create.c new file mode 100644 index 0000000..8f32072 --- /dev/null +++ b/tests/gem_create.c @@ -0,0 +1,166 @@ +/* + * Copyright © 2015 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.
