https://bugzilla.novell.com/show_bug.cgi?id=223045 Summary: irqbalance (i586) 0.0.9-58 not working, OK when replaced with 0.0.9-43 from SuSE 9.x Product: SUSE Linux 10.1 Version: Final Platform: i686 OS/Version: SuSE Linux 10.1 Status: NEW Severity: Enhancement Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: casualprogrammer@yahoo.com QAContact: qa@suse.de During boot irqbalance service is shown as bypassed. Trying to start it from YaST results in message "not configured", according to the sources there is nothing to configure. When uninstalling the package and replacing it with 0.0.9-43 it works fine, cat /proc/interrupts shows even distribution over both CPUs.

The most descritive is https://bugzilla.novell.com/show_bug.cgi?id=171500. There seem to be issues with SiS chipsets ( how are they identified ) an a general notion of "If two people are working in an office with one phone line, only one can take calls" this is absurd. If there are multiple CPUs then they got to share the load, no matter how many sockets are involved, otherwise the whole concept of SMP is lead "ad absurdum" Casual -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

------- Comment #15 from casualprogrammer@yahoo.com 2007-04-17 22:58 MST -------
Asking this same question from Intel (Arjan van de Ven
While I can enable it and watch it distribute IRQs, I came across the irqbalance website and thought it a good idea to try irqbalance-0.55.tar.gz out.
I can compile and run it alright, but only for short periods of time, it gets terminated before long, without any ( at least I found none ) indication why this should be so.
you have a single socket system where the cores share the L2 cache. For these systems dynamic irq balancing isn't really the right approach; they don't really have need. What irqbalance 0.55 will do is set up a static spread of the interrupts over the 2 cores, and then exit to avoid wasting CPU cycles. This should provide the best possible behavior on your system..." So it seems OK to run the service also for dual core single socket systems, as all it will do ( and does for me ) is setting up a statistical distribution and quit. In /etc/init.d/irq_balancer change " if [ $PHYS -gt 1 ] || [ $PROC -gt 1 -a $PHYS -eq 0 ] ; then" to " if [ $PROC -gt 1 ] ; then" -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
