2012-10-24perf trace: Support interrupted syscallsArnaldo Carvalho de Melo1-0/+4

2012-09-11perf tools: include wrapper for magic.hIrina Tirdea1-1/+1
perf is currently including magic.h directly from the kernel. If the glibc magic.h is also included, this leads to warnings that the constants are redefined. This happens on some systems (e.g. Android). Redefinition errors on Android: In file included from util/util.h:79:0, from util/cache.h:5, from util/abspath.c:1: util/../../../include/linux/magic.h:5:0: error: "AFFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:53:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:19:0: error: "EFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:61:0: note: this is the location of the previous definition util/../../../include/linux/magic.h:26:0: error: "HPFS_SUPER_MAGIC" redefined [-Werror] bionic/libc/include/sys/vfs.h:67:0: note: this is the location of the previous definition Only two constants from magic.h are used by perf (DEBUGFS_MAGIC and SYSFS_MAGIC).

2012-01-24perf tools: Fix broken build by defining _GNU_SOURCE in MakefileDavid Daney1-1/+0
When building on my Debian/mips system, util/util.c fails to build because commit 1aed2671738785e8f5aea663a6fda91aa7ef59b5 (perf kvm: Do guest-only counting by default) indirectly includes stdio.h before the feature selection in util.h is done. This prevents _GNU_SOURCE in util.h from enabling the declaration of getline(), from now second inclusion of stdio.h, and the build is broken. There is another breakage in util/evsel.c caused by include ordering, but I didn't fully track down the commit that caused it. The root cause of all this is an inconsistent definition of _GNU_SOURCE, so I move the definition into the Makefile so that it is passed to all invocations of the compiler and used uniformly for all system header files. All other #define and #undef of _GNU_SOURCE are removed as they cause conflicts with the definition passed to the compiler. All the features.h definitions (_LARGEFILE64_SOURCE _FILE_OFFSET_BITS=64 and _GNU_SOURCE) are needed by the python glue code too, so they are moved to BASIC_CFLAGS, and the misleading comments about BASIC_CFLAGS are removed. This gives me a clean build on x86_64 (fc12) and mips (Debian).

2010-06-17perf record: Add option to avoid updating buildid cacheStephane Eranian1-0/+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.

2010-06-05perf buildid: add perfconfig option to specify buildid cache dirStephane Eranian1-0/+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.

2010-05-14perf report: Report number of events, not samplesArnaldo Carvalho de Melo1-0/+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.

2009-12-28perf record: Introduce a symtab cacheArnaldo Carvalho de Melo1-0/+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.

2009-11-11perf tools: Bring linear set of section headers for featuresFrederic Weisbecker1-0/+3
Build a set of section headers for features right after the datas. 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.

2009-08-17perf tools: Add perf traceFrederic Weisbecker1-0/+1
This adds perf trace into the set of perf tools. It is written to fetch the tracepoint samples from perf events and display them, according to the events information given by the debugfs files through the util/trace* tools. It is a rough first shot and doesn't yet handle the cpu, timestamps fields and some other things. Example: perf record -f -e workqueue:workqueue_execution:record -F 1 -a perf trace kblockd/0-236 [000] 0.000000: workqueue_execution: thread=:236 func=cfq_kick_queue+0x0 kondemand/0-360 [000] 0.000000: workqueue_execution: thread=:360 func=do_dbs_timer+0x0 kondemand/0-360 [000] 0.000000: workqueue_execution: thread=:360 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 kondemand/1-361 [000] 0.000000: workqueue_execution: thread=:361 func=do_dbs_timer+0x0 Todo: - A lot of things!
