It's numa (two cores, one ram ctrlr per core, one core per package). I'm running an x86 kernel, btw, not 64bit. I have CONFIG_X86_HT set, and it looks like it gets the pkg id from the apic (there's only one in multicore packages?), but i might be reading it wrong. My dmseg overflows before syslog starts, so all i could gather is: Mar 23 12:04:25 zero kernel: Brought up 2 CPUs Mar 23 12:04:25 zero kernel: CPU0 attaching sched-domain: Mar 23 12:04:25 zero kernel: domain 0: span 3 Mar 23 12:04:25 zero kernel: groups: 1 2 Mar 23 12:04:25 zero kernel: CPU1 attaching sched-domain: Mar 23 12:04:25 zero kernel: domain 0: span 3 Mar 23 12:04:25 zero kernel: groups: 2 1 I don't know how the scheduling domains work, and i'm too busy to look it up right now. -- Tom Vier DSA Key ID 0x15741ECE - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
