Enable QOS feature on AMD. Following QoS sub-features are supported on AMD if the underlying hardware supports it: - L3 Cache allocation enforcement - L3 Cache occupancy monitoring - L3 Code-Data Prioritization support - Memory Bandwidth Enforcement (Allocation) The specification is available at: https://developer.amd.com/wp-content/resources/56375.pdf There are differences in the way some of the features are implemented. Separate those functions and add those as vendor specific functions. The major difference is in MBA feature: - AMD uses CPUID leaf 0x80000020 to initialize the MBA features. - AMD uses direct bandwidth value instead of delay based on bandwidth values. - MSR register base addresses are different for MBA. - AMD allows non-contiguous L3 cache bit masks.
