> Subject: [dpdk-dev] [PATCH v8 1/1] eventdev: add new software event
> timer adapter
>
> This patch introduces a new version of the event timer adapter software
> PMD. In the original design, timer event producer lcores in the primary and
> secondary processes enqueued event timers into a ring, and a service core in
> the primary process dequeued them and processed them further. To
> improve performance, this version does away with the ring and lets lcores
> insert timers directly into timer skiplist data structures; the service core
> directly accesses the lists as well, when looking for timers that have expired.
>
> To compare the burst and non-burst performance of the original and new
> versions of the software event timer adapter, I ran the following
> commands:
>
> $ sudo ./build/app/dpdk-test-eventdev -c 0xFFE -s 0xC --vdev=event_sw0 \
> -- --test=perf_queue --plcores=4,5,6 --wlcore=7,8,9 --stlist=p \ --
> prod_type_timerdev --worker_deq_depth=32

> -- --test=perf_queue --plcores=4,5,6 --wlcore=7,8,9 --stlist=p \ --
> prod_type_timerdev_burst --worker_deq_depth=32
>
> With the new version, I see a 151% improvement in throughput for the non-
> burst case, and a 270% improvement in throughput for the burst case.
> I also see a 53% improvement in arm latency in the non-burst case and a 65%
> improvement in arm latency in the burst case.
>
> Note: To perform the test, I commented out a check in the original version
> that checks the adapter tick interval against a minimum value.
