2010-10-04perf trace scripting: Fix extern struct definitionsStephane Eranian1-2/+2
Both python_scripting_ops and perl_scripting_ops have two global definitions. 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.

2010-09-07perf: Add a script to show packets processingKoki Sanagi3-0/+477
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.

2010-08-27perf: Initialize callchains roots's childen hitsFrederic Weisbecker1-0/+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.

2010-08-25perf hists browser: Introduce "expand/collapse all callchains" actionArnaldo Carvalho de Melo1-6/+106
When looking at a callchains enabled perf data file one can find it tiresome to start with all callchains collapsed and then to have to go one by one expanding them. 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.

2010-08-22perf: Support for callchains mergeFrederic Weisbecker3-0/+59
If we sort the histograms by comm, which is the default, we need to merge some of them, typically different thread histograms of a same process, or just same comm. 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.

2010-08-10perf symbols: Ignore mapping symbols on ARMDave Martin1-0/+10
ARM ELF files use symbols with special names $a, $t, $d to identify regions of ARM code, Thumb code and data within code sections. This can cause confusing output from the perf tools, especially for partially stripped binaries, or binaries containing user-added zero-sized symbols (which may occur in hand-written assembler which hasn't been fully annotated with .size directives). This patch filters out these symbols at load time.
