Hence using gem_mmap_device_coherent() which wraps the mmap options in the order of gem_mmap_offset / gem_mmap / mmap_gtt Signed-off-by: Ramalingam C --- tests/prime_mmap.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tests/prime_mmap.c b/tests/prime_mmap.c index fc985784407b..1433424109c8 100644 --- a/tests/prime_mmap.c +++ b/tests/prime_mmap.c @@ -85,8 +85,8 @@ test_correct(void) dma_buf_fd = prime_handle_to_fd(fd, handle); igt_assert(errno == 0); - /* Check correctness vs GEM_MMAP_GTT */ - ptr1 = gem_mmap__gtt(fd, handle, BO_SIZE, PROT_READ); + /* Check correctness vs GEM_MMAP */ + ptr1 = gem_mmap__device_coherent(fd, handle, 0, BO_SIZE, PROT_READ); ptr2 = mmap(NULL, BO_SIZE, PROT_READ, MAP_SHARED, dma_buf_fd, 0); igt_assert(ptr1 != MAP_FAILED); igt_assert(ptr2 != MAP_FAILED); -- 2.20.1 _______________________________________________ igt-dev mailing list igt-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/igt-dev
