| |
Hello
I am using two Intel Giga NICs in a DELL PowerEdge 4600 with 2 Intel XEON 1.8GHz CPUs. The matherboard is ServerWorks GC-HE. The OS is RedHat 7.2, and the release of kernel is "2.4.7-10smp".
The CPU0 has very heavy interrupt traffic, you can see the following information: >>>>> [root@giga root]# cat /proc/interrupts CPU0 CPU1 0: 395117 0 IO-APIC-edge timer 1: 653 0 IO-APIC-edge keyboard 2: 0 0 XT-PIC cascade 8: 1 0 IO-APIC-edge rtc 12: 23 0 IO-APIC-edge PS/2 Mouse 14: 2 0 IO-APIC-edge ide0 18: 30 0 IO-APIC-level aic7xxx 19: 86013 0 IO-APIC-level eth0 20: 10394 0 IO-APIC-level aic7xxx 21: 30 0 IO-APIC-level aic7xxx 27: 5480873 0 IO-APIC-level e1000 39: 164889152 0 IO-APIC-level e1000 NMI: 0 0 LOC: 395013 395012 ERR: 0 MIS: 0 >>>>>
The kernel's SMP option is enable, but the CPU1 is always idle. How to balance the interrpupts between two CPUs? If you are convenient, please give me some advice quickly.
Thank you!
Best regard
