From 359d5106a2ff4ffa2ba129ec8f54743c341dabfc Mon Sep 17 00:00:00 2001 From: Koki Sanagi Date: Mon, 23 Aug 2010 18:47:09 +0900 Subject: perf: Add a script to show packets processing Add a perf script which shows packets processing and processed time. It helps us to investigate networking or network devices. If you want to use it, install perf and record perf.data like following. 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 processing rx: show only rx packets processing dev=: show processing on this device debug: work with debug mode. It shows buffer status. For example, if you want to show received packets processing associated 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 a transmit/receive sequence.
