platform/x86: hfi: Introduce AMD Hardware Feedback Interface Driver
The AMD Heterogeneous core design and Hardware Feedback Interface (HFI) provide behavioral classification and a dynamically updated ranking table for the scheduler to use when choosing cores for tasks.
There are two CPU core types defined: Classic and Dense. Classic cores are the standard performance cores, while Dense cores are optimized for area and efficiency.
Heterogeneous compute refers to CPU implementations that are comprised of more than one architectural class, each with two capabilities. This means each CPU reports two separate capabilities: "perf" and "eff".
Each capability lists all core ranking numbers between 0 and 255, where a higher number represents a higher capability.
Heterogeneous systems can also extend to more than two architectural classes.
The purpose of the scheduling feedback mechanism is to provide information to the operating system scheduler in real time, allowing the scheduler to direct threads to the optimal core during task scheduling.
All core ranking data are provided by the PMFW via a shared memory ranking table, which the driver reads and uses to update core capabilities to the scheduler. When the hardware updates the table, it generates a platform interrupt to notify the OS to read the new ranking table.
