Ryzen Mobile Power/Performance With Linux 6.3's New AMD P-State EPP Driver

With Linux 6.3 there is the new AMD P-State EPP driver code for supporting the ACPI Energy Performance Preference (EPP) to further enhance the power efficiency and performance of modern AMD systems on Linux. Last week I ran some benchmarks of AMD EPYC with the new AMD P-State EPP mode while in today's article is a look at the laptop impact with Ryzen Mobile when comparing ACPI CPUFreq, the existing AMD P-State driver, and the new AMD P-State EPP mode and its multiple different preferences.
