This is why I am asking for this, we would like to re-= write and keep sync with FreeBSD community. We want to know the latest statu= s and where we can start from. I can see that projects/numa and also Jeff's repo have more functions implem= ented, and one userland API proposal on github. There is no update for a lon= g time for all. There is also the wiki page at https://wiki.freebsd.org/NUMA. I am not sure i= f it is outdated or not.
