While I do applaud your efforts and am thankful that FreeBSD even
exists on the ppc64 ( big endian? ) platform I suspect there are very
few actual users of 12.x in the wild. If any. I guess traffic out of
ports may reveal some statistics. I have tried to use FreeBSD 13 and of
course CURRENT on an old PowerMac quad PPC970MP. The results a very
underwhelming given that there is no way to use more than a single CPU
core. That has been discussed and explained in depth here before. I do
not see that ever being fixed as the much more popular POWER8 and POWER9
based systems are a far better target to focus on. In short, dropping
support on powerpc64/12 seems perfectly reasonable. Unless of course
someone with a spare million dollars shows up at the door and really
wants these things to work.
