Future patches will add add itback if needed at run-time.Signed-off-by: Tom Zanussi <tom.zanussi@linux.intel.com>Acked-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net> List of files: /linux-6.15/tools/perf/scripts/python/bin/netdev-times-record Wed, 10 Nov 2010 14:08:20 +0000 Tom Zanussi <tom.zanussi@linux.intel.com> http://172.16.0.5:8080/history/linux-6.15/tools/perf/scripts/python/bin/netdev-times-record#359d5106 perf: Add a script to show packets processingAdd a perf script which shows packets processing and processedtime. It helps us to investigate networking or network devices.If you want to use it, install perf and record perf.data likefollowing.If you set script, perf gathers records until it ends.If not, you must Ctrl-C to stop recording.And if you want a report from record,If you use some options, you can limit the output.Option is below.tx: show only tx packets processingrx: show only rx packets processingdev=: show processing on this devicedebug: work with debug mode. It shows buffer status.For example, if you want to show received packets processingassociated with eth4,106133.171439sec cpu=0 irq_entry(+0.000msec irq=24:eth4) | softirq_entry(+0.006msec) | |---netif_receive_skb(+0.010msec skb=f2d15900 len=100) | | | skb_copy_datagram_iovec(+0.039msec 10291::10291) | napi_poll_exit(+0.022msec eth4)This perf script helps us to analyze the processing time of atransmit/receive sequence.Signed-off-by: Koki Sanagi <sanagi.koki@jp.fujitsu.com>Acked-by: David S.
