The issue is when we disable hardcap before kernel boot up, after kernel bring up, any changes of _PPC will update scaling_max_freq properly. If we enable hardcap before kernel boot up, after kernel bring up, even we disable it, scaling_max_freq does not be updated to max frequency, the max frequency just up to the value when bring up. Review related codes I found the limit came from user_policy.max, means when we set user_policy.max to 1000MHZ when boot up, then any changes of _PPC could not enlarge the scaling_max_freq, I think this is not as expected? please advise.
