I can't get it to work either. Even when completely disabeling ACPI CPUFreq, it doesnt work, I cannot get it to activate. AMD previously stated they will revise some parts in upcoming linux release 5.19, making it easier to activate, but I cant officially confirm it right now.
In anycase, pstate isnt that much better than ACPI CPUFreq so youre not missing out on much. Infact, in some cases its worse and consumes more power idle.
