Existence and support for SMBA and BMEC is already visible to user space in your current series: * On a system that supports SMBA with the needed kernel support users will find the /sys/fs/resctrl/info/SMBA directory with enumerated properties as well as SMBA within the schemata file. * On a system that supports BMEC with the needed kernel support users will find the relevant files listed within /sys/fs/resctrl/info/L3_MON/mon_features.
