--- Comment #1 from Mario Limonciello (AMD) (mario.limonciello@amd.com) ---
I believe your CPU should support the MSR approach. It should have been fixed
by "ACPI: CPPC: Don't require _OSC if X86_FEATURE_CPPC is supported". You can
see in your lscpu output the "cppc" flag is present.
That other patch won't matter. That patch was specifically to fix "ACPI: bus:
Set CPPC _OSC bits for all and when CPPC_LIB is supported".
A few asks:
1) Does acpi-cpufreq work? Or that's broken too from this commit?
2) Can you please share your full dmesg and an acpidump?
3) If you turn on dynamic debugging for drivers/acpi/cppc_acpi.c do you see
"Flexible address space capability not supported"? I would expect yes from
that bisect.
