The addresses are pretty inconsequential, since they're virtual addresses. It would be nice to be able to profile how far a CPU gets in its launch (writing a value to a well-known address, 0xc000000000000010, or such, anywhere in the bottom 256 bytes of space really). If you add writes to that address, we can track the progress at panic time. I'd presume all APs would behave the same way, so no need for lock management, or isolation between them. - Justin _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "[email protected]"
