Hi Rafael, I have identified some regressions with the schedutil governor which happen due to one of your patches that got merged in 4.12-rc1.
This series fixes all the drivers which provide a ->target_index() callback but doesn't fix the drivers which provide ->target() callback. Such platforms need to implement the ->resolve_freq() callback in order to get this fixed and I only had hardware for testing intel_pstate, which I fixed in this series. I am wondering if there is another way to fix this issue (than what I tried) or if we should revert the offending commit (39b64aa1c007) and look for other solutions. Anyway, this series has the necessary patches to fix it.
