[Intel-gfx] [PATCH i-g-t v5 0/7] CRC testing with Chamelium improvements

[Jani Nikula]

For future reference, please post new versions of the entire series as
new threads. When posting new versions of just some individual patches,
in-reply-to each patch being replaced is fine. I think this is more
clear, and also gives patchwork a better chance to apply the right
patches for testing (not that it does igt CI, but that might change).

BR,
Jani.
