Hi,

Regarding "GMKS" method, it does not have "version" related information. So , its unlikely to impact any older platforms.
However, I got it confirmed that definition of GMKS method itself doesn't include any workaround feature.

But, since its getter function , I also think its harmless and if it workaround some issue then I don’t see any concern.

How about publishing schematics / specs, so we can confirm what it's
really doing ?

In recent decades I've learn to mistrust vendor-provided firmware
(especially when it comes to acpi). The reason why I'm currently
bisecting AMD's AGESA blob, in order to completely replace it.

It's a tedious job, had to write my own analysis tool, but step
by step making progress. (and already learned they've been using a
pretty inefficient compiler that can't even inline trivial memcpy().
Probably some older msvc ... :p)
