Either that or:
Total 32
Available 16

which looks fractionally simpler to parse. But I don't have strong feelings.

Interesting. So there is no real benefit from "0=tl;1=_" ... you are using
up two counters, just not reporting them on socket 1.

Why have this complexity in mbm_assign_control syntax?

You could have just {grouppath}/{allocation}

where allocation is one of _, t, l, tl
