Subject: [dpdk-dev] [RFC 0/4] new function to create control threads
Date: Fri, 8 Dec 2017 11:26:53 +0100 [thread overview]
Message-ID: <20171208102657.2699-1-olivier.matz@6wind.com> (raw)
This patchset targets 18.05.
It applies on top of 17.11 + [1] and [2].
Some parts of dpdk use their own management threads. Most of the time,
the affinity of the thread is not properly set: it should not be scheduled
on the dataplane cores, because interrupting them can cause packet losses.
This patchset introduces a new wrapper for thread creation that does
the job automatically, avoiding code duplication.
