This is definately the right place.

We only support the uninteresting sysmp(2) operations MP_PGSIZE,
MP_NPROCS and MP_NAPROCS as part of the IRIX binary compatibility.

We don't yet support SMP - nobody has so far provided a SMP machine to
me plus the hardware documentation. However I think you might also
consult about sysmp(2) and pset(1) with the people from
email@example.com, the stuff is definately of interest to the
users of Alpha, i386 and Sparc systems on which SMP is supported.
Linux/MIPS is so far not yet a very widespread OS, but if you nevertheless
wish to port your code to Linux/MIPS, then I as one of the core
developers would like to offer you my support. I'd also like to point
out that Linux/MIPS as far as technically possible is binary compatible
beyond the machines of just one manufacturer.
