Hello, This is a patchset to do 3 things to improve ibmvnic performance: 1. Assign affinity hints to ibmvnic queue irq's 2. Update affinity hints on cpu hotplug events 3. Introduce transmit packet steering (XPS) NOTE: If irqbalance is running, you need to stop it from overriding our affinity hints. To do this you can do one of: - systemctl stop irqbalance - ban the ibmvnic module irqs - you must have the latest irqbalance v9.2, the banmod argument was broken before this - in /etc/sysconfig/irqbalance -> IRQBALANCE_ARGS="--banmod=ibmvnic" - systemctl restart irqbalance Nick Child (3): ibmvnic: Assign IRQ affinity hints to device queues ibmvnic: Add hotpluggable CPU callbacks to reassign affinity hints ibmvnic: Update XPS assignments during affinity binding drivers/net/ethernet/ibm/ibmvnic.c | 239 ++++++++++++++++++++++++++++- drivers/net/ethernet/ibm/ibmvnic.h | 5 + include/linux/cpuhotplug.h | 1 + 3 files changed, 244 insertions(+), 1 deletion(-)
