cpufreq: intel_pstate: Use passive mode by default without HWP

2020-04-17T15:04:38Z

After recent changes allowing scale-invariant utilization to be used on x86, the schedutil governor on top of intel_pstate in the passive mode should be on par with (or better than) the active mode "powersave" algorithm of intel_pstate on systems in which hardware-managed P-states (HWP) are not used, so it should not be necessary to use the internal scaling algorithm in those cases. Accordingly, modify intel_pstate to start in the passive mode by default if the processor at hand does not support HWP of if the driver is requested to avoid using HWP through the kernel command line. Among other things, that will allow utilization clamps and the support for RT/DL tasks in the schedutil governor to be utilized on systems in which intel_pstate is used. Signed-off-by: Rafael J.

Documentation: cpufreq: Move legacy driver documentation

2020-03-02T10:31:06Z

There are three legacy driver documents in Documentation/cpu-freq/ that were added years ago and converting them each to the .rst format is rather pointless, even though there is some value in preserving them. However, if they are preserved, they need to go into the admin-guide part of cpufreq documentation where they belong (at least to a certain extent). To preserve them with minimum amount of changes and put them into the right place, and make it possible to process them into HTML (and other formats) along with the rest of the documentation, move them each as a "literal text" block into a separate section of a single .rst "wrapper" file under Documentation/admin-guide/pm/. While at it, repair the PCC specification URL in one of them. Signed-off-by: Rafael J. Wysocki
