How about? "default": By default resctrl assumes each control and monitor group has a hardware counter. Hardware that does not support 'mbm_cntr_assign' mode will still allow to create control or monitor groups up to num_rmids supported. In that case reading the mbm_total_bytes and mbm_local_bytes may report 'Unavailable' if there is no counter associated with that group. -- Thanks Babu Moger
