Which baseline exposes MB_MON in resctrl?
Reinette
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.
Were these tests written against a spec as opposed to the actual MPAM enabling
code? How could it have been tested?
Reinette
Oh, I should add that the current Linux arm_mpam resctrl glue code is
still under review and has not been merged. Therefore, this RFC is based
on the Linux distribution OS test, so please ignore this issue. I will
remove this in the next version.
