Subject: [PATCH 2/2] cpufreq/amd-pstate: Add EPP tunings for Zen6 client platforms
Date: Mon, 31 Aug 2026 00:46:30 -0500 [thread overview]
Message-ID: <20260831054630.1745997-3-superm1@kernel.org> (raw)
In-Reply-To: <20260831054630.1745997-1-superm1@kernel.org>
Zen6 client platforms perform better with individual tunings for
different core types. Add initial EPP tuning values for those
platforms.
