In the MPAM architecture reference manual, the memory-system component
includes the cache and memory channel controller, among others. The memory
channel controller can implement a memory bandwidth usage monitor.
I noticed that arm_mpam maps other classes to l3 in the resctrl glue code,
so I will fix this in the next version.
Regards,
Yifan Wu
