/proc/irq/<irq-number>/smp_affinity
For example masks for irqs could be :
irq 97 - 0x1
99 - 0x2
103 - 0x4
104 - 0x8
That way, you are hardcoding on which cpu the particular irqs should land.

Hi, everyone
The interrupts of my ixgbevf driver occurs only Core 0
although the user space "irqbalance" serivce is working.
How can I distribute the interrupt of RX in ixgbevf to all cores?
Is there any kernel compile option for it ?
cat /proc/interrupts | grep "isv"
97: 8 0 0 0 0
0 0 0 PCI-MSI-edge isv0-rx-0
99: 7 0 0 0 0
0 0 0 PCI-MSI-edge isv0:lsc
103: 2059 0 0 0 0
0 0 0 PCI-MSI-edge isv2-rx-0
104: 14 0 0 0 0
0 0 0 PCI-MSI-edge isv2-tx-0
105: 1 0 0 0 0
0 0 0 PCI-MSI-edge isv2:mbx
"isv" is netdevice name of my ixgbevf.
Thanks in advance.
