[Intel-gfx] [PATCH i-g-t 0/6] Make kms_pipe_crc_basic cover pipe A + eDP on HSW

[Damien Lespiau]

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.

  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
