Subject: [PATCH v2 3/3] arm64, topology: enable use of init_cpu_capacity_cppc()
Date: Tue, 24 Aug 2021 11:56:51 +0100 [thread overview]
Message-ID: <20210824105651.28660-4-ionela.voinescu@arm.com> (raw)
In-Reply-To: <20210824105651.28660-1-ionela.voinescu@arm.com>
Now that the arch topology driver provides a method of setting CPU
capacity values based on information on highest performance from CPPC,
use this functionality on arm64 platforms.
