Subject: [dpdk-dev] Ring PMD: why are stats counters atomic?
Date: Tue, 10 May 2016 11:13:08 +0200	[thread overview]
Message-ID: <CAPwdgqjR1eSt5ewcdm93WNT-ZX7ychWUSdSZvbU22Rapat3ybQ@mail.gmail.com> (raw)

Hello,

Per-queue stats counters are defined as rte_atomic64_t, in the tx/rx
functions, they are atomically increased if the rings have the multiple
consumers/producer flag enabled.

According to the design principles, the application should not invoke those
functions on the same queue on different cores, then I think that atomic
increasing is not necessary.

Is there something wrong with my reasoning?, If not, I am willing to send a
patch.

Thank you very much,

Mauricio V,
