* perf record: Add option to avoid updating buildid cacheStephane Eranian2010-06-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | There are situations where there is enough information in the perf.data to process the samples. Updating the buildid cache may add unecessary overhead in terms of disk space and time (copying large elf images). A persistent option to do this already exists via the perfconfig file, simply do: [buildid] dir = /dev/null This patch provides a way to suppress builid cache updates on a per-run basis. It addds a new option, -N, to perf record. Buildids are still generated in the perf.data file. Cc: David S.

* perf buildid: add perfconfig option to specify buildid cache dirStephane Eranian2010-06-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the ability to specify an alternate directory to store the buildid cache (buildids, copy of binaries). By default, it is hardcoded to $HOME/.debug. This directory contains immutable data. The layout of the directory is such that no conflicts in filenames are possible. A modification in a file, yields a different buildid and thus a different location in the subdir hierarchy. You may want to put the buildid cache elsewhere because of disk space limitation or simply to share the cache between users. It is also useful for remote collect vs. local analysis of profiles. This patch adds a new config option to the perfconfig file. Under the tag 'buildid', there is a dir option. For instance, if you have: $ cat /etc/perfconfig [buildid] dir = /var/cache/perf-buildid All buildids and binaries are be saved in the directory specified. The perf record, buildid-list, buildid-cache, report, annotate, and archive commands will it to pull information out. The option can be set in the system-wide perfconfig file or in the $HOME/.perfconfig file. Cc: David S.

* perf annotate: Add TUI interfaceArnaldo Carvalho de Melo2010-05-221-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | When annotating multiple entries, for instance, when running simply as: $ perf annotate the right and left keys, as well as TAB can be used to cycle thru the multiple symbols being annotated. If one doesn't like TUI annotate, disable it by editing ~/.perfconfig and adding: [tui] annotate = off Just like it is possible for report.

* perf report: Report number of events, not samplesArnaldo Carvalho de Melo2010-05-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Number of samples is meaningless after we switched to auto-freq, so report the number of events, i.e. not the sum of the different periods, but the number PERF_RECORD_SAMPLE emitted by the kernel. While doing this I noticed that naming "count" to the sum of all the event periods can be confusing, so rename it to .period, just like in struct sample.data, so that we become more consistent. This helps with the next step, that was to record in struct hist_entry the number of sample events for each instance, we need that because we use it to generate the number of events when applying filters to the tree of hist entries like it is being done in the TUI report browser.

* perf record: Introduce a symtab cacheArnaldo Carvalho de Melo2009-12-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now a cache will be created in a ~/.debug debuginfo like hierarchy, so that at the end of a 'perf record' session all the binaries (with build-ids) involved get collected and indexed by their build-ids, so that perf report can find them. This is interesting when developing software where you want to do a 'perf diff' with the previous build and opens avenues for lots more interesting tools, like a 'perf diff --graph' that takes more than two binaries into account. Tunables for collecting just the symtabs can be added if one doesn't want to have the full binary, but having the full binary allows things like 'perf rerecord' or other tools that can re-run the tests by having access to the exact binary in some perf.data file, so it may well be interesting to keep the full binary there. Space consumption is minimised by trying to use hard links, a 'perf cache' tool to manage the space used, a la ccache is required to purge older entries. With this in place it will be possible also to introduce new commands, 'perf archive' and 'perf restore' (or some more suitable and future proof names) to create a cpio/tar file with the perf data and the files in the cache that _had_ perf hits of interest. There are more aspects to polish, like finding the right vmlinux file to cache, etc, but this is enough for a first step.

| * perf tools: Bring linear set of section headers for featuresFrederic Weisbecker2009-11-111-0/+3

Each implemented feature will have one of such section header that provides the offset and the size of the data manipulated by the feature. The trace informations have moved after the data and are recorded on exit time. The new layout is as follows: ----------------------- ___ [ magic ] | [ header size ] | [ attr size ] | [ attr content offset ] | [ attr content size ] | [ data offset ] File Headers [ data size ] | [ event_types offset ] | [ event_types size ] | [ feature bitmap ] v [ attr section ] [ events section ] ___ [ X ] | [ X ] | [ X ] Datas [ X ] | [ X ] v ___ [ Feature 1 offset ] | [ Feature 1 size ] Features headers [ Feature 2 offset ] | [ Feature 2 size ] v [ Feature 1 content ] [ Feature 2 content ] ----------------------- We have as many feature's section headers as we have features in use for the current file. Say Feat 1 and Feat 3 are used by the file, but not Feat 2. Then the feature headers will be like follows: [ Feature 1 offset ] | [ Feature 1 size ] Features headers [ Feature 3 offset ] | [ Feature 3 size ] v There is no hole to cover Feature 2 that is not in use here. We only need to cover the needed headers in order, from the lowest feature bit to the highest. Currently we have two features: HEADER_TRACE_INFO and HEADER_BUILD_ID. Both have their contents that follow the feature headers. Putting the contents right after the feature headers is not mandatory though. While we keep the feature headers right after the data and in order, their offsets can point everywhere. We have just put the two above feature contents in the end of the file for convenience. The purpose of this layout change is to have a file format that scales while keeping it simple: having such linear feature headers is less error prone wrt forward/backward compatibility as the content of a feature can be put anywhere, its location can even change by the time, it's fine because its headers will tell where it is. And we know how to find these headers, following the above rules.
