IPv6 Fragmentation:

configure. In the bnx2x driver, for instance, this parameter is called

num_queues. A typical RSS configuration would be to have one receive queue

for each CPU if the device supports enough queues, or otherwise at least

one for each cache domain at a particular cache level (L1, L2, etc.).

one for each memory domain, where a memory domain is a set of CPUs that

share a particular memory level (L1, L2, NUMA node, etc.).

The indirection table of an RSS device, which resolves a queue by masked

hash, is usually programmed by the driver at initialization. The

interrupt processing forms a bottleneck. Spreading load between CPUs

decreases queue length. For low latency networking, the optimal setting

is to allocate as many queues as there are CPUs in the system (or the

NIC maximum, if lower). Because the aggregate number of interrupts grows

with each additional queue, the most efficient high-rate configuration

NIC maximum, if lower). The most efficient high-rate configuration

is likely the one with the smallest number of receive queues where no

CPU that processes receive interrupts reaches 100% utilization. Per-cpu

load can be observed using the mpstat utility.

receive queue overflows due to a saturated CPU, because in default

mode with interrupt coalescing enabled, the aggregate number of

interrupts (and thus work) grows with each additional queue.

Per-cpu load can be observed using the mpstat utility, but note that on

processors with hyperthreading (HT), each hyperthread is represented as

a separate CPU. For interrupt handling, HT has shown no benefit in

initial tests, so limit the number of queues to the number of CPU cores

in the system.

RPS: Receive Packet Steering

== Suggested Configuration

For a single queue device, a typical RPS configuration would be to set

the rps_cpus to the CPUs in the same cache domain of the interrupting

the rps_cpus to the CPUs in the same memory domain of the interrupting

CPU. If NUMA locality is not an issue, this could also be all CPUs in

the system. At high interrupt rate, it might be wise to exclude the

interrupting CPU from the map since that already performs much work.

receive queue is mapped to each CPU, then RPS is probably redundant

and unnecessary. If there are fewer hardware queues than CPUs, then

RPS might be beneficial if the rps_cpus for each queue are the ones that

share the same cache domain as the interrupting CPU for that queue.

share the same memory domain as the interrupting CPU for that queue.

RFS: Receive Flow Steering

corresponding socket structure for the flow (e.g. a TCP connection).

This transmit queue is used for subsequent packets sent on the flow to

prevent out of order (ooo) packets. The choice also amortizes the cost

of calling get_xps_queues() over all packets in the connection. To avoid

of calling get_xps_queues() over all packets in the flow. To avoid

ooo packets, the queue for a flow can subsequently only be changed if

skb->ooo_okay is set for a packet in the flow. This flag indicates that

there are no outstanding packets in the flow, so the transmit queue can

  void pm_runtime_irq_safe(struct device *dev);

    - set the power.irq_safe flag for the device, causing the runtime-PM

      suspend and resume callbacks (but not the idle callback) to be invoked

      callbacks to be invoked with interrupts off

  void pm_runtime_mark_last_busy(struct device *dev);
