Since you seem to want to keep the flexibility for a possible future

on each domain to avoid ABI problems should that future arrive.
$ cat num_mbm_counters

$ cat available_mbm_cntrs
0=12;1=9
Good point.
Working on this now. Wanted to confirm if we really need domain specific
information?
To me, it does not seem necessary for the user. User cannot make any
decisions based on this information.
All user wants to know is if there are global counters available.
$ cat num_mbm_counters
32
$ cat available_mbm_cntrs
15
This approach paints resctrl into an ABI corner where it can't later
update resctrl to track counters per-domain. Maybe you'll never want to do that,
but some other architecture might want to have that flexibility.
Ok. Fine. Lets keep the per-domain counters.
