Various X86PlatformPlugin errors in log

[atanvarno]

I was looking at log show --last boot | grep -i ACPI and noticed a bunch of these records.

Anyone knows what this is about..? Gigabyte B550I Aorus AX, BIOS F16e.

This is IOReg, X86PlatformPlugin:

The only place that has anything related to this is this ancient post on InsanelyMac with typical incomprehensible solution/fix. I have no idea what the author meant by

and count from index 0 (top) till you reach it.
For example in my case, I only have one turbo state so the next highest non-Turbo would be 1

...since I don't get how to recognise what is non-turbo in the list of Packages he cites as example.

AFAIK these are normal because AMD CPUs don't support Intel's XCPM, it happens on my desktop too.

That makes sense.

Looking at ACPI on Gigabyte B550I BIOS F16e, I see ACPI table (attached) that contains code similar to the mentioned post on InsanelyMac.
There's also this in IOReg, which I assume is set as some kind of fallback.



Wish I had time to learn how XCPM works and what it is looking for...
