 For OS interface, it uses MBA CTRL via libpqos (OS support available in Linux kernel 4.18 or later).
 For MSRs, the tool adjusts MBA configuration by itself based on local memory B/W.
 Intel(R) RDT/AMD PQoS allocation operations of the utility are done via libpqos library. Class of service 0 (CLOS0)
