I actually just use acpi_cpufreq
Bah. Hit 'send' mistakenly too soon, thus the abrupt end and unfinished quoting removal.
And don't ask me why it's acpi_pstate-driven. I have X86_AMD_PSTATE=y, but
/sys/devices/system/cpu/cpufreq/policy0/scaling_driver
clearly says 'acpi-cpufreq'. Maybe I'm looking in the wrong place. My dmesg says
amd_pstate: the _CPC object is not present in SBIOS or ACPI disabled
which is presumably the reason my machine uses acpi-pstate.
I will also test out your other questions, but I need to go back and do more pull requests first.
