Subject: [PATCH 3/4] cpufreq/amd-pstate: Call cppc_set_epp_perf in the reenable function
Date: Wed, 23 Oct 2024 10:21:10 +0000 [thread overview]
Message-ID: <20241023102108.5980-4-Dhananjay.Ugwekar@amd.com> (raw)
In-Reply-To: <20241023102108.5980-1-Dhananjay.Ugwekar@amd.com>
The EPP value being set in perf_ctrls.energy_perf is not being propagated
to the shared memory, fix that.
