2012-04-25perf: Have perf use the new libtraceevent.a librarySteven Rostedt1-7/+13
The event parsing code in perf was originally copied from trace-cmd but never was kept up-to-date with the changes that was done there. The trace-cmd libtraceevent.a code is much more mature than what is currently in perf. This updates the code to use wrappers to handle the calls to the new event parsing code. The new code requires a handle to be pass around, which removes the global event variables and allows more than one event structure to be read from different files (and different machines). But perf still has the old global events and the code throughout perf does not yet have a nice way to pass around a handle. A global 'pevent' has been made for perf and the old calls have been created as wrappers to the new event parsing code that uses the global pevent. With this change, perf can later incorporate the pevent handle into the perf structures and allow more than one file to be read and compared, that contains different events.

2012-04-25perf: Separate out trace-cmd parse-events from perf filesSteven Rostedt1-0/+2
Move the trace-event-parse.c code that originally came from trace-cmd into their own files. The new file will be called trace-parse-events.c, as the name of trace-cmd's file was parse-events.c too, but it conflicted with the parse-events.c file in perf that parses the command line. This tries to update the code with mimimal changes. Perf specific code stays in the trace-event-parse.[ch] files and the common parsing code is now in trace-parse-events.c and trace-parse-events.h.

The perf python extention (perf.so) file lacks its dependencies in the Makefile so that it cannot be refreshed if one of source files it depends is changed. Fix it by putting them in a separate file and processing it in both of Makefile and setup.py.

distclean as an alias for clean was removed from the perf Makefile by commit a3d1ee10d1bf4520af3d44c1aa6cd46956ec4fd7 However, that commit neglected to remove it from the help output of the perf Makefile, which could result in a user trying the following. $ cd tools/perf/ $ make help | grep distclean distclean - alias to clean $ make distclean make: *** No rule to make target `distclean'. Stop. This patch removes it from the Makefile help output.

2012-01-30perf tools: Fix broken build by defining _GNU_SOURCE in MakefileDavid Daney1-5/+2
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).

2011-10-07perf top: Reuse the 'report' hist_entry/hists classesArnaldo Carvalho de Melo1-4/+0
This actually fixes several problems we had in the old 'perf top': 1. Unresolved symbols not show, limitation that came from the old "KernelTop" codebase, to solve it we would need to do changes that would make sym_entry have most of the hist_entry fields. 2. It was using the number of samples, not the sum of sample->period. And brings the --sort code that allows us to have all the views in 'perf report', for instance: [root@emilia ~]# perf top --sort dso PerfTop: 5903 irqs/sec kernel:77.5% exact: 0.0% [1000Hz cycles], (all, 8 CPUs) ------------------------------------------------------------------------------ 31.59% libcrypto.so.1.0.0 21.55% [kernel] 18.57% libpython2.6.so.1.0 7.04% libc-2.12.so 6.99% _backend_agg.so 4.72% sshd 1.48% multiarray.so 1.39% libfreetype.so.6.3.22 1.37% perf 0.71% libgobject-2.0.so.0.2200.5 0.53% [tg3] 0.48% libglib-2.0.so.0.2200.5 0.44% libstdc++.so.6.0.13 0.40% libcairo.so.2.10800.8 0.38% libm-2.12.so 0.34% umath.so 0.30% libgdk-x11-2.0.so.0.1800.9 0.22% libpthread-2.12.so 0.20% libgtk-x11-2.0.so.0.1800.9 0.20% librt-2.12.so 0.15% _path.so 0.13% libpango-1.0.so.0.2800.1 0.11% libatlas.so.3.0 0.09% ft2font.so 0.09% libpangoft2-1.0.so.0.2800.1 0.08% libX11.so.6.3.0 0.07% [vdso] 0.06% cyclictest ^C All the filter lists can be used as well: --dsos, --comms, --symbols, etc. The 'perf report' TUI is also reused, being possible to apply all the zoom operations, do annotation, etc. This change will allow multiple simplifications in the symbol system as well, that will be detailed in upcoming changesets.

2011-09-23perf tools: Add support for disabling -Werror via WERROR=0Darren Hart1-1/+8
GCC often introduces new warnings with lots of false positives - breaking -Werror builds. WERROR=0 allows one to build perf without much fuss - while still encouraging people to send patches to avoid the fuss of having to type WERROR=0. Bisecting back to commits that produce a (mostly harmless) warning on some compilers is more difficult. With WERROR=0 one could bisect without worrying about harmless warnings.

2011-06-16tools/perf: Fix static build of perf toolMathias Krause1-1/+1
To build a statically linked version of the perf tool all needed libraries must be added in the correct order to get the symbols resolved. Currently this is broken when, e.g. python or newt support is enabled -- libpython needs libpthread which is an unconditional link dependency of the perf tool; libslang needs libm, another unconditional dependency. To solve the problem in the long run without the need to keep track of transitive library dependencies, simply make the linker look at the EXTLIBS multiple times until it has all symbols resolved.
