This is a testcase with multiple planes. The idea here is the following - draw a uniform frame with blue color - grab crc for reference - put planes randomly on top with the same blue color - punch holes with black color into the primary framebuffer - ideally the planes should cover these holes so that the output is the identical to reference crc - composite all with one ioctl call - grab crc and verify that the reference crc is equal - repeat this for dozen iterations to maximize coverage v2: Keep a logfile on random number seeds per subtest that are not skipped due to unmet test requirements Signed-off-by: Mika Kahola <mika.kahola@intel.com> --- tests/kms_plane_multiple.c | 421 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 421 insertions(+) create mode 100644 tests/kms_plane_multiple.c
