NEWS: mention staprun -T
commit a31f94d12de20b5a1d0489815ab2754c0a17cbba
Author: Frederic Turgis <f-turgis@ti.com>
Date: Wed May 23 21:21:06 2012 -0400
Allow tuning of reader thread ppoll timeout value
Default value of 200ms causes too many wake-ups for embedded platforms
low power use-cases. Timeout of several seconds is expected on these.
New option is -T x where x is timeout in ms.
* runtime/staprun/common.c (parse_args): Parse -T option.
(usage): Mention it.
* runtime/staprun/relay.c (reader_thread): Use -T value to override default
polling interval.
* runtime/staprun/staprun.8: Document it.
