I am investigating an issue where the ixgbe (82599) device is hung and
I think I have traced it to the driver not getting interrupts. I have
MSI/X enabled, with 2 rx/tx queues.
I am trying to understand this bit of code in the MSI/X setup:
if (ixgbe_enable_msix) {
ixgbe_configure_ivars(adapter);
/* Set up auto-mask */ <<== THIS BIT
if (hw->mac.type == ixgbe_mac_82598EB)
IXGBE_WRITE_REG(hw, IXGBE_EIAM, IXGBE_EICS_RTX_QUEUE);
else {
IXGBE_WRITE_REG(hw, IXGBE_EIAM_EX(0), 0xFFFFFFFF);
IXGBE_WRITE_REG(hw, IXGBE_EIAM_EX(1), 0xFFFFFFFF);
}
}
Does this mean that ixgbe_disable_queue() is not needed in the msi/x
interrupt handler - ixgbe_msix_que()?
