Re: What is FreeBSD 12 equivalent to Linux' "sysctl -w vm.nr_hugepages=1280"?

There is no equivalent setting on FreeBSD (as of yet), and there's
no way to explicitely request huge pages (super pages, large pages,
whatever you call them) on FreeBSD in the mmap()/shmget() interfaces
(as there is in Linux) (there is MAP_ALIGNED_SUPER in FreeBSD to
"maximize the potential use of large (“super”) pages", but from the
desription alone that looks like slightly different semantics - and
based on how I read those sementics, that randomX code in question
should either have a fallback or avoid large pages on any BSD).
