In this series, three feature control support for amd_pstate has been added.
1. EPP: User can control Energy Performance Preference (EPP) value, which conveys user's performance vs energy preference to platform. This feature is present on amd_pstate and intel_pstate active mode.
2. amd_pstate mode switch: amd_pstate has various working modes such as 'active', 'passive' and 'guided', which can be changed dynamically.
3. Turbo boost: Turbo boost feature is present in amd_pstate as well as acpi-cpufreq. By default this is enabled, but user can control this feature dynamically.
These features can be controlled with `cpupower set` command. The options are respectively --epp, --amd-pstate-mode, --turbo-boost
Also, make cpupower recognise amd-pstate-epp driver.
Changelog: v2->v3: - Use common prefix to recognise amd-pstate-epp driver. - Picked up review tag from Mario.
v1->v2: - Drop patch 1, which was amd-pstate-epp driver rename change. - Picked ACKs from Ray.
Wyes Karny (5): cpupower: Recognise amd-pstate active mode driver cpupower: Add is_valid_path API cpupower: Add EPP value change support cpupower: Add support for amd_pstate mode change cpupower: Add turbo-boost support in cpupower
