So, it's not an SMP option :today, as I understand it. : :-Kurt Although, this is more a deficiency in the way FreeBSD is designed. Using an APIC is nice, but not absolutely necessary. All we need are good specs on how VIA's SMP cpus interact with each other and we could support it. I like the 11 watts specified in the paper. That *is* low power for the class of system they are selling. I don't see a clock specification but I assume it is going to be at least as fast as the ~900MHz M-9000. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
