Subject: [PATCH 1/3] x86, ACPI: rename init_freq_invariance_cppc to arch_init_invariance_cppc
Date: Fri, 14 May 2021 10:53:37 +0100 [thread overview]
Message-ID: <20210514095339.12979-2-ionela.voinescu@arm.com> (raw)
In-Reply-To: <20210514095339.12979-1-ionela.voinescu@arm.com>
init_freq_invariance_cppc() was called in acpi_cppc_processor_probe(),
after CPU performance information and controls were populated from the
per-cpu _CPC objects.
But these _CPC objects provide information that helps with both CPU
(u-arch) and frequency invariance. Therefore, change the function name
to a more generic one, while adding the arch_ prefix, as this function
is expected to be defined differently by different architectures.
