Subject: [PATCH 0/6] cpupower: Add various feature control support for amd_pstate
Date: Mon, 12 Jun 2023 11:36:09 +0000 [thread overview]
Message-ID: <20230612113615.205353-1-wyes.karny@amd.com> (raw)
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, fix amd-pstate-epp driver name and make cpupower recognise
amd-pstate-epp driver.
Wyes Karny (6):
amd-pstate: Make amd-pstate epp driver name hyphenated
cpupower: Recognise amd-pstate active mode driver
cpupower: Add is_sysfs_present API
cpupower: Add EPP value change support
cpupower: Add support for amd_pstate mode change
cpupower: Add turbo-boost support in cpupower
