Struct GuaranteedPerformance 

pub struct GuaranteedPerformance;

ACPI Specification 6.5; 8.4.6.1.1.6 Guaranteed Performance

Guaranteed Performance Register conveys to OSPM a Guaranteed Performance level, which is the current maximum sustained performance level of a processor, taking into account all known external constraints (power budgeting, thermal constraints, AC vs DC power source, etc.). All processors are expected to be able to sustain their guaranteed performance levels simultaneously. The guaranteed performance level is required to fall in the range [Lowest Performance, Nominal performance], inclusive.

If this register is not implemented, OSPM assumes guaranteed performance is always equal to nominal performance.

Notify events of type 0x83 to the processor device object will cause OSPM to re-evaluate the Guaranteed Performance Register. Changes to guaranteed performance should not be more frequent than once per second. If the platform is not able to guarantee a given performance level for a sustained period of time (greater than one second), it should guarantee a lower performance level and opportunistically enter the higher performance level as requested by OSPM and allowed by current operating conditions.
