Subject: [dpdk-dev] [Bug 815] Incorrect average cycles print in Service Summary
Date: Mon, 27 Sep 2021 09:00:35 +0000 [thread overview]
Message-ID: <bug-815-3@http.bugs.dpdk.org/> (raw)
https://bugs.dpdk.org/show_bug.cgi?id=815
Bug ID: 815
Summary: Incorrect average cycles print in Service Summary
Product: DPDK
Version: 20.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: eventdev
Assignee: dev@dpdk.org
Reporter: heng.wang@ericsson.com
Target Milestone: ---
The avg is incorrect in the service summary:
========[ Services ]========
Services Summary
red_0: stats 1 calls 4116836818 cycles 1895089655988 avg: 0
txa_0: stats 1 calls 1074980347 cycles 377139519878 avg:
350
rte_event_eth_rx_adapter_0: stats 1 calls 871649367 cycles 2820073051742
avg: 3235
worker_service: stats 1 calls 3522889906 cycles 1017830212880
avg: 0
timer_service: stats 1 calls 3326551197 cycles 748157460934
avg: 0
The avg in the last 2 rows are incorrect. I think it might be some race
condition between the service run updating the cycles, and the service print
accessing the cycles.
