By the way: the only reason I can get ofwdump -ap output on the PowerMac G5's that I've access to is because of the extra patches that I run. On a normal FreeBSD build it crashes in open firmware. https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237590 is about the crashes and what caused the problem. A more direct way to get the crash than ofwdump -ap is: ofwdump -Plog /packages/obp-tftp ofwdump usage that avoids that area should work as I remember. >> I posted the G4 timebase sync code at https://reviews.freebsd.org/D29136 and will add G5 code on as I get the platform data for them. > > > Other than the PowerMac11,2 and PowerMac7,2 (G5s) and PowerMac3,6 (G4s) > the rest of the PowerMacs are single socket/single core.
