How to distribute IRQs to all cores

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.
