I just looked my ASRock B460M-ITX's firmware settings. You are right, the option "Enable/Disable Intel Speed Shift Technology support" has the same help message. But I don't know if the bug / current fix disables any function that had worked before. Based on various online resources, my understanding is "Intel Speed Shift" = HWP (Hardware P-state) in Linux, and I can see kernel message say it always works (intel_pstate: HWP enabled).

The issue is that the ACPI _OSC method supports ONLY the UUID of the "PCI root bridge device", but not any other, but linux is looking for CPPC support with the "Platform-Wide OSPM Capabilities" uuid, which does not exist anywhere in the firmware. bios engineers told me that this is all part of AMDs AGESA thingie, and they won't be able to add support for this, at least on current (i.e. zen3-supporting) platforms. Could this be worked around, by first checking whether any _CPC objects exist, and maybe a matching PCC entry?

Oh I see this was fixed recently with fbd74d16 ("ACPI: CPPC: Fix enabling CPPC on AMD systems with shared memory").

If you still have one with Zen open a new issue. The remaining issue is that reportedly from this thread a number of Intel systems the firmware will mask the _OSC during negotiation. When the _OSC is masked a dynamic SSDT doesn't get loaded. Someone needs to confirm if: * This is intended behavior that firmware masks the _OSC (and thus CPPC v2 shouldn't be used on these systems). or * This is purely a firmware bug and CPPC v2 should be used and that should be quirked when the _OSC is evaluated on the affected systems (or later so the SSDT still loads).
