From 8f9bbc408b6f704e84d0ae78e6093005ad58d4fe Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 11 Aug 2010 14:51:47 -0300 Subject: perf ui browser: Abstract some more slang operations Browsers don't have to deal with absolute coordinates, just using (row, column) and leaving the rest to ui_browser is better and removes one more UI backend detail from the browsers. Also shorten the percent_color setting idiom, removing some more direct libslang calls.

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.

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.

One in trace-event-scripting.c and one in their respective scripting-engine modules. The issue is that depending on the linker order one definition or the other is chosen. One is uninitialized (bss), while the other is initialized. If the uninitialized version is chosen, then perf does not function properly. This patch fixes this by adding the extern prefix to the definitions in trace-event-scripting.c. Cc: David S.
