From 2caeb8c0141dcf488f2d68aa8e8c44d1f85ed28b Mon Sep 17 00:00:00 2001 From: Pawel Wodkowski Date: Tue, 24 Feb 2015 17:33:24 +0100 Subject: [PATCH] examples/l2fwd-jobstats: new example This app demonstrate usage of new rte_jobstats library. It is basically the orginal l2fwd with following modifications to met library requirements: - main_loop() was split into two jobs: forward job and flush job. Logic for those jobs is almost the same as in original application. - stats is moved to rte_alarm callback to not introduce overhead of printing. - stats are expanded to show rte_jobstats statistics. - added new parameter '-l' to automatic thousands separator. Comparing original l2fwd and l2fwd-jobstats apps will show approach what is needed to properly write own application with rte_jobstats measurements. New available statistics: - Total and % of fwd and flush execution time - management time - overhead of rte_timer + overhead of rte_jobstats library - Idle time and % of time spent waiting for fwd or flush to be ready to execute. - per job execution time and period.
