By skipping the whole test suite, this patch is just hiding the fact that PC8 doesn't work on BDW. Yes, PC8 on BDW (specifically) won't work without runtime PM, but that's not true for HSW on some Kernels. The proper fix to the bug above is to fix RC6 on BDW, or revert the revert. > > I might be wrong, but I thought we don't need backward compatibility in > igt.
