What's the current state of highmem on the G4? Does it work, not work, kinda work, only work on UP... ? I hope to have a dual 7450 G4 with 1 GB RAM within a week, at which point I'll be able to work on highmem seriously. -VAL ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/

It's supposed to work. However, I'm having reports of dual 7450 with 1G or 1.5G of RAM locking up, I haven't been able to track those down. Is this an Apple machine ? The 7450 has a bug that prevents use on SMP with HW hash table walk. Apple is supposed to implement a HW workaround for this on their machines, but if it's not an Apple machine, then you may have to implement software TLB load.
