[Intel-gfx] [IGT] IGT/tests/firmware: Test firmware loading by reading debugfs
Read debugfs and sysfs entries to check for GuC loading conditions. The patch is still WIP. Once all check conditions are covered, it can be extended to huc debugfs file too.

I agree totally. I am not very happy about it either.
