Cover letter [PATCH 0/2] cpufreq: intel_pstate: Run in the passive mode by default on systems without HWP
Hi All,
These two patches modify the intel_pstate driver to run in the passive mode by default on systems without HWP (refer to the changelog of patch [2/2] for the motivation part).
Internal testing of the system performance in 5.6-rc indicates that the difference between the active mode with the powersave scaling algorithm and the passive mode with the schedutil governor should be negligible for the majority of users, so it should be safe to change the default behavior of the driver as per the above.
Patch [1/2] makes changes to select the schedutil governor and set it as the default one when intel_pstate is selected in Kconfig.
Patch [2/2] changes intel_pstate to start in the passive by default if HWP is not supported (or if it is disabled via the kernel command line).
Please refer to the patch changelogs for more information.
Thanks!
