I'd rather this patch exclude 8xx along with PReP for now; the 8xx TLB handlers could be made to accept arbitrary task sizes, but not without slightly slowing them down (not that they're currently optimal -- IIUC, using the hardware tablewalk assist is expensive due to serialization on mtspr, and it doesn't really do anything that rlwimi can't do). I'm not sure it's worth it -- does anyone really need more than 2GB userspace on an 8xx? At the very least, we should have the 8xx patch in place before turning it on. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
