Resctrl provides a user-configurable option mbm_assign_on_mkdir that determines if a counter will automatically be assigned to an RMID, event pair when its associated monitor group is created via mkdir. Enable mbm_assign_on_mkdir by default to automatically assign counters to the two default events (MBM total and MBM local) of a new monitoring group created via mkdir. This maintains backward compatibility with original resctrl support for these two events. Unassign and free counters belonging to a monitoring group when the group is deleted. Monitor group creation does not fail if a counter cannot be assigned to one or both events. There may be limited counters and users have the flexibility to modify counter assignments at a later time. Log the error message "Failed to allocate counter for <event> in domain <id>" in /sys/fs/resctrl/info/last_cmd_status when a new monitoring group is created but counter assignment failed.
