[dpdk-dev] [PATCH v3 08/14] ring: allow enqueue fns to return free space value

[Thomas Monjalon]

2017-03-24 17:10, Bruce Richardson:
> Add an extra parameter to the ring enqueue burst/bulk functions so that
> those functions can optionally return the amount of free space in the
> ring. This information can be used by applications in a number of ways,
> for instance, with single-producer queues, it provides a max
> enqueue size which is guaranteed to work. It can also be used to
> implement watermark functionality in apps, replacing the older
> functionality with a more flexible version, which enables apps to
> implement multiple watermark thresholds, rather than just one.
