sfxge(4): always be ready to receive batched events

When the low-latency firmware variant is running, it is reported as not
being capable of batching RX events, but it can still do so if the
FORCE_EV_MERGING flag is set on an RXQ.  Therefore we need to handle
batched RX events even if the capability isn't set.

If this bug is fixed in the firmware such that the capability is set
even when running the low-latency firmware variant, it will almost
always be reported so I don't think we lose much by removing the check.

hselasky [Fri, 3 Jun 2016 08:35:07 +0000 (08:35 +0000)]
Use insertion sort instead of bubble sort in TCP LRO.

Replacing the bubble sort with insertion sort gives an 80% reduction
in runtime on average, with randomized keys, for small partitions.

If the keys are pre-sorted, insertion sort runs in linear time, and
even if the keys are reversed, insertion sort is faster than bubble
sort, although not by much.

8 years agoxen-netfront: switch to using an interrupt handler

xen-netfront: switch to using an interrupt handler

In order to use custom taskqueues we would have to mask the interrupt, which
is basically what is already done for an interrupt handler, or else we risk
loosing interrupts. This switches netfront to the same interrupt handling
that was done before multiqueue support was added.

8 years agoxen-netfront: always keep the Rx ring full of requests

xen-netfront: always keep the Rx ring full of requests

This is based on Linux commit 1f3c2eba1e2d866ef99bb9b10ade4096e3d7607c from
David Vrabel:

A full Rx ring only requires 1 MiB of memory.  This is not enough memory
that it is useful to dynamically scale the number of Rx requests in the ring
based on traffic rates, because:

a) Even the full 1 MiB is a tiny fraction of a typically modern Linux
   VM (for example, the AWS micro instance still has 1 GiB of memory).

b) Netfront would have used up to 1 MiB already even with moderate
   data rates (there was no adjustment of target based on memory
   pressure).

c) Small VMs are going to typically have one VCPU and hence only one
   queue.

Keeping the ring full of Rx requests handles bursty traffic better than
trying to converge on an optimal number of requests to keep filled.
