We currenly have a bug on HSW where asking for the panel fitter CRC when the power well is down returns 0xffffffff, but kms_pipe_crc_basic passes as it only tests that the CRCs obtained for a FB are consistent over time. We consistently read 0xffffffff, so the test was passing. With this series we now scan out 2 different fbs and make sure the CRCs for those two fbs are indeed, different. This makes: $ sudo ./tests/kms_pipe_crc_basic --run-subtest read-crc-pipe-A-frame-sequence fail when the power well is down, while: $ sudo ./tests/kms_pipe_crc_basic --run-subtest read-crc-pipe-B-frame-sequence succeeds, using pipe B turning the power well on. -- Damien Damien Lespiau (6): kms_pipe_crc_basic: Split the main test function a bit more kms_pipe_crc_basic: Cycle between 2 differently colored buffer kms_pipe_crc_basic: Make the number of CRCs a parameter kms_pipe_crc_basic: Bump the number of collected CRCs to 60 kms_pipe_crc_basic: Add a bit a debugging output lib: Add a --igt-debug command line option lib/igt_core.c | 5 +++ tests/kms_pipe_crc_basic.c | 97 +++++++++++++++++++++++++++++++++------------- 2 files changed, 76 insertions(+), 26 deletions(-) -- 1.8.3.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
