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. Best Regards, J.Hwan Kim
