I was wondering if this works differently on Intel. I was trying to figure out on 2 socket intel system if we can create two separate resctrl groups sharing the same CLOSID (one group using CLOSID 1 on socket 0 and another group CLOSID 1 socket 1). No. We cannot do that. Even though hardware supports separate allocation for each domain, resctrl design does not support that. -- Thanks Babu Moger
