FreeBSD 12 should work fine on powerpc. HOWEVER, you cannot do a buildworld/installworld and expect everything to work right. I broke, with the Tier-2 hammer, the ABI by changing the time_t type from 32-bits to 64-bits, to match all other archs (except i386), so all ports must be rebuilt, a straight upgrade will not work for base. The easiest thing to do would be to backup your data and reinstall from scratch. > I can't comment on the SMP features... > > I'm running FreeBSD head on a G4 MacMini without any problems > (however, I'm not running a GUI on it).

So you might want to try disabling smp > also on your G4 system in case you experience problems. Andreas Tobler found a commit I made increasing KVA from ~7.5GB to 32GB likely broke things on the G5. Unfortunately, I was unable to test on the G5 before committing, as my only FreeBSD-supporting G5 died back in July, and it worked well enough on the POWER9 which uses HPT MMU as well, so I'm pretty confused about it. This only affects powerpc64, not powerpc. SMP on the G4 should be unchanged. > > Best regards > Michael > > > > --jau If FreeBSD 12 does not work on the Quicksilver, I really want to know. I have a dual processor MDD I can boot up to verify if you do run into problems. I haven't turned it on in 2 years, and it's sitting in the closet. - Justin
