Subject: [PATCH 1/8] x86/amd: Move amd_get_highest_perf() from amd.c to cppc.c
Date: Mon, 26 Aug 2024 16:13:51 -0500	[thread overview]
Message-ID: <20240826211358.2694603-2-superm1@kernel.org> (raw)
In-Reply-To: <20240826211358.2694603-1-superm1@kernel.org>

From: Mario Limonciello <mario.limonciello@amd.com>

To prepare to let amd_get_highest_perf() detect preferred cores
it will require CPPC functions. Move amd_get_highest_perf() to
cppc.c to prepare for 'preferred core detection' rework.

No functional changes intended.
