Re: SMP System but only CPU#0 being used?
from the smp man page. 1) make sure you have options SMP in your kernel and is built and compiled OK. 2)put the lines in the /boot/loader.conf and reboot the system machdep.cpu_idle_hlt=0 machdep.hlt_cpus=0 machdep.hlt_logical_cpus=0 machdep.hyperthreading_allowed=1 == should work... my cpus are pentiuns HT or pentius 4 dual core Lenzi ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

The CPU is a LGA775 Pentium-M with EMT64 I think, I remember the CPU box saying dual core on it (not core duo though). Pentium 4 was socket 478 from memory or did Intel do a Pentium 4 in LGA775 too? Yes, they had P4 in LGA775 for quiet some time. I'm quiet sure that a 3GHz CPU is NetBurst architecture, pentium-m never reached that clock. But regardless of the architecture, therre were relad Dula Core Pentium 4 (xxxD) and the old hyperthreaded. If it was a Dual Core CPU FreeBSD wouldn't report Logical CPUs per core but Cores per package -Harry ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] -- OmniSEC - UNIX und Windows Netzwerke - Sicher Harald Schmalzbauer Flintsbacher Str. 3 80686 München +49 (0) 89 18947781 +49 (0) 160 93860101 USt-IdNr.: DE253184753 ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

What am i missing here? Is this system truly multiprocessor, or hyperthreaded? Hyperthreading is disabled by default, due to security concerns. Check the value of the sysctl machdep.hypterhtreading_enabled. If you turn it on and the second CPU starts being used, then you have an HT system, and not a multiprocessor system. Then you can decide whether you're willing to accept the potential security risk of enabling hyperthreading. -- Bill Moran http://www.potentialtech.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
