"As a reminder, AMD P-State is only supported with AMD Zen 2 processors and newer. AMD P-State depends upon ACPI Collaborative Processor Performance Contols (CPPC) and that is only with Zen 2 and newer -- Zen 1 / Zen 1+ will not be seeing any support. You also need to ensure CPPC is enabled in your BIOS in case it happened to be disabled. Many motherboard vendors do have a "ACPI CPPC" option in the BIOS that can be set to enabled or auto on Zen 2 and newer processors." src: https://www.phoronix.com/scan.php?page=news_item&px=AMD-P-State-How-To
