Subject: [PATCH v5 0/5] amd-pstate Dynamic EPP and raw EPP
Date: Mon, 5 Jan 2026 23:14:36 -0600 [thread overview]
Message-ID: <20260106051441.60093-1-superm1@kernel.org> (raw)
Dynamic EPP allows the kernel to register amd-pstate as part of
a platform profile. It will change EPP modes matching the user's
preference to the platform profile sysfs files as well as power
adapter state.
Raw EPP allows userspace to write integers to
energy_performance_preference.
v4: https://lore.kernel.org/linux-pm/20250321022858.1538173-1-superm1@kernel.org/
Mario Limonciello (5):
cpufreq/amd-pstate: Add dynamic energy performance preference
cpufreq/amd-pstate: add kernel command line to override dynamic epp
cpufreq/amd-pstate: Add support for platform profile class
cpufreq/amd-pstate: Add support for raw EPP writes
cpufreq/amd-pstate-ut: Add a unit test for raw EPP
