Subject: [PATCH v2 1/5] Revert "ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn"
Date: Mon, 4 May 2026 18:01:37 -0500 [thread overview]
Message-ID: <20260504230141.484743-2-mario.limonciello@amd.com> (raw)
In-Reply-To: <20260504230141.484743-1-mario.limonciello@amd.com>
Some older systems don't support CPPC in the firmware and this just makes
noise for them when booting. Drop back to debug.
This reverts commit 21fb59ab4b9767085f4fe1edbdbe3177fbb9ec97.
Fixes: 21fb59ab4b976 ("ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn")
