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.

So associate 'E' with "Expand all callchains" and 'C' with "Collapse all callchains". This way now one can have the top level view and then switch to/from having all callchains expanded. More work is needed to allow expanding just from one branch down to its leaves.

But during this merge, we forgot to merge callchains. So imagine we have three threads (tids: 1000, 1001, 1002) that belong to comm "foo". tid 1000 got 100 events tid 1001 got 10 events tid 1002 got 3 events Once we merge these histograms to get a per comm result, we'll finally get: "foo" got 113 events The problem is if we merge 1000 and 1001 histograms into 1002, then the end merge result, wrt callchains, will be only callchains that belong to 1002. This is because we haven't handled callchains in the merge. Only those from one of the threads inside a common comm survive. It means during this merge, we can lose a lot of callchains. Fix this by implementing callchains merge and apply it on histograms that collapse.

* | | perf: Initialize callchains roots's childen hitsFrederic Weisbecker2010-08-271-0/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each histogram entry has a callchain root that stores the callchain samples. However we forgot to initialize the tracking of children hits of these roots, which then got random values on their creation. The root children hits is multiplied by the minimum percentage of hits provided by the user, and the result becomes the minimum hits expected from children branches. If the random value due to the uninitialization is big enough, then this minimum number of hits can be huge and eventually filter every children branches. The end result was invisible callchains. All we need to fix this is to initialize the children hits of the root.

| | | | | | | | | | | | | | | | | As part of ongoing effort to reduce the coupling with libnewt, browsers are being changed to return the exit key. The annotate browser is not returning it as expected by builtin-annotate when annotating multiple symbols (when 'perf annotate' is called without specifying a symbol name). Fix it by returning the exit key and also adding the RIGHT key as a exit key so that going to the next symbol in the TUI can work again.

Remove some fields from default view, add logging feature. Use infinite time out for poll(), mark more detail fields. Fix byte ordering macro. Add decoding of iso data and lock packets. Add flag to indicate data length field. Add cycle start packet decoding, add --iso and --cycle-start flags. Distinguish between phy-packets and 0-length iso data. Fix transaction and stats view.

This will support power frequency tracing by all cpufreq drivers trace_power_frequency did not trace frequency changes correctly when the userspace governor was used or when CPU cores' frequency depend on each other. -> Moving this into the CPUFREQ_POSTCHANGE notifier and pass the cpu which gets switched automatically fixes this.
