Dear experts,
I spent a week to separate interrupt vectors(tx,rx,link) in my
following hardware:
CPU : 4-core xeon 5420
On-board NIC: Intel Pro 1000 (attached as eth0,eth1)
External NIC : Intel Pro 1000 PT DualPort Server Adaptor
(attached as eth2,3)
Kenel version: 2.6.27 (stable)
E1000E driver : 0.5.8.2-NAPI with IntMode of '2'
And I change CPU affinity of eth2 to 'f'.
After booting, my interrupt shown as follows:
CPU0 CPU1 CPU2 CPU3
0: 74 84 81 78 IO-APIC-edge timer
1: 2 2 2 2 IO-APIC-edge i8042
9: 0 0 0 0 IO-APIC-fasteoi acpi
12: 28 29 29 28 IO-APIC-edge i8042
14: 16 16 18 16 IO-APIC-edge ata_piix
15: 0 0 0 0 IO-APIC-edge ata_piix
19: 0 0 0 0 IO-APIC-fasteoi ata_piix
500: 157506458 157500913 157629609 157627832 PCI-MSI-edge eth2
501: 0 1 1 3 PCI-MSI-edge
502: 695543 701485 709524 711300 PCI-MSI-edge eth0
503: 287909 287484 1407 1413 PCI-MSI-edge ioc0
506: 0 0 0 0 PCI-MSI-edge aerdrv
507: 0 0 0 0 PCI-MSI-edge aerdrv
508: 0 0 0 0 PCI-MSI-edge aerdrv
509: 0 0 0 0 PCI-MSI-edge aerdrv
510: 0 0 0 0 PCI-MSI-edge aerdrv
511: 0 0 0 0 PCI-MSI-edge aerdrv
NMI: 0 0 0 0 Non-maskable interrupts
LOC: 54779616 54377785 53932855 52836722 Local timer interrupts
RES: 1122690 644047 1157453 586999 Rescheduling interrupts
CAL: 612 660 629 226 function call interrupts
TLB: 80069 90854 80994 88350 TLB shootdowns
TRM: 0 0 0 0 Thermal event interrupts
THR: 0 0 0 0 Threshold APIC interrupts
SPU: 0 0 0 0 Spurious interrupts
I found a strange interrupt vector for interrupt number '501'. But I
don't know what it is.
The output of ethtool for eth2 is as follows:
driver: e1000e
version: 0.5.8.2-NAPI
firmware-version: 5.11-2
bus-info: 0000:07:00.0
Any 'HINT' would be highly appreciated.
Thanks in advanec.
