Yeah, I'm not sure about that either. I have
$ grep -r . /sys/devices/system/cpu/cpu*/topology/ppin | cut -d: -f 2 | uniq -c
32 0xxxxx
32 times the same number.
Wouldn't
/sys/devices/system/node/
be a better place?
Even if those were logical nodes, it would still be less needless
replication and that would be one more way for root to figure out which
logical nodes belong to the same physical package... :-)
Hmm.
