  • ab81f3fd3   perf top: Reuse the 'report' hist_entry/hists classes ... Browse Code »

    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)

    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.

  • 9e59e0995   perf tools: Add support for disabling -Werror via WERROR=0 ... Browse Code »

    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.

    1

    Builds for 32-bit perf binaries on a 64-bit host currently fail
    with this error:

    [...]
    bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages:
    bench/../../../arch/x86/lib/memcpy_64.S:29: Error: bad register name `%rdi'

    bench/../../../arch/x86/lib/memcpy_64.S:61: Error: bad register name `%rdi'
    ...

    The problem is the detection of the host arch without considering passed in
    flags. This change fixes 32-bit builds via:

    make EXTRA_CFLAGS=-m32

    and 64-bit builds still reference the memcpy_64.S.

  • 203db2952   tools/perf: Fix static build of perf tool ... Browse Code »

    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.

  • ced465c40   perf tools: Makefile: PYTHON{,_CONFIG} to bandage Python 3 incompatibility ... Browse Code »

    Currently, Python 3 is not supported by perf's code; this
    can cause the build to fail for systems that have Python 3
    installed as the default python:

    python{,-config}

    The Correct Solution is to write compatibility code so that
    Python 3 works out-of-the-box.

    However, users often have an ancillary Python 2 installed:

    python2{,-config}

    Therefore, a quick fix is to allow the user to specify those
    ancillary paths as the python binaries that Makefile should
    use, thereby avoiding Python 3 altogether; as an added benefit,
    the Python binaries may be installed in non-standard locations
    without the need for updating any PATH variable.

    This commit adds the ability to set PYTHON and/or PYTHON_CONFIG
    either as environment variables or as make variables on the
    command line; the paths may be relative, and usually only PYTHON
    is necessary in order for PYTHON_CONFIG to be defined implicitly.
    Some rudimentary error checking is performed when the user
    explicitly specifies a value for any of these variables.

    In addition, this commit introduces significantly robust makefile
    infrastructure for working with paths and communicating with the
    shell; it's currently only used for handling Python, but I hope
    it will prove useful in refactoring the makefiles.

    Thanks to:

    Raghavendra D Prabhu

    for motivating this patch.

  • 3643b133f   perf tools: Makefile: Clean up `python/perf.so' rule ... Browse Code »

    There is no need for a subshell or an explicit `export';
    as per the POSIX Shell Command Language specification:

    http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_09_01
    http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_10_02

    It is only necessary to include the environment variable
    assignment just before the command to be run.

    Also, it is better to use single-quotes, because GNU make
    might expand `$(BASIC_CFLAGS)' into something that the shell
    could interpret within double-quotes.

  • a3d1ee10d   perf tools: Makefile: Remove various and sundry cruft ... Browse Code »
    86

    This commit squashes several commits that remove:

    unnecessary uname calls
    `sh -c'
    BUILT_INS and QUIET_BUILT_IN

    They have no effect, and the `fixup-builtins' and `check-builtins.sh'
    scripts don't even exist.

    RUNTIME_PREFIX

    It's currently never anything but unset, and it's apparently
    only meaningful when Microsoft Windows is the operating system
    (according to the source for git).

    TEST_PROGRAMS
    EXTRA_PROGRAMS
    unused SHELL_PATH_SQ portions
    unused test for V=2
    useless exports

    Only when `V' is undefined (that is, only when the value of `V'
    is empty) is `export V' performed, which just has the effect of
    placing the empty-valued variable `V' in the environment.

    The only other script to make use of `V' is `Documentation/Makefile',
    which only checks whether `V' is undefined (that is, whether the value
    of `V' is empty); hence, the `export V' has no effect whatsoever.

    Similarly, `export QUIET_GEN' is useless because it will only have
    a non-empty value when `V' has an empty-value, and when `V' has
    an empty-value, `QUIET_GEN' is always explicitly set in every
    script in which it is used.

    `DESTDIR' is only ever defined by the user via the environment
    or the command line, both of which are automatically exported
    to sub-make processes. Furthermore, no non-make sub-scripts
    make use of `DESTDIR' as an environment variable.

    No other scripts use `perfexec_instdir'.

    unused QUIET_SUBDIR{0,1}
    TAR and RPMBUILD
    PTHREAD_LIBS
    Maintainer's dist rules and commands
    distclean target
    Test suite coverage testing
    PRINT_DIR and NO_SUBDIR
    `configure' target
    NO_CURL
    @@PERF_VERSION@@ substitution

    Without the sed command, all of the rule's commands can be reduced
    to a single line that copies a file and sets the permissions properly
    in the process.

    `make test' echo line
    template_instdir
    PERF-BUILD-OPTIONS
    double-colon rules

    The use of double-colon rules seems misguided or vestigial git.

    Essentially hard-coded $(SCRIPTS) expansion

    (cgroups) for both perf stat and perf record. It is possible to monitor
    multiple cgroup in parallel. There is one cgroup per event. The cgroups to
    monitor are passed via a new -G option followed by a comma separated list of
    cgroup names.

    The cgroup filesystem has to be mounted. Given a cgroup name, the perf tool
    finds the corresponding directory in the cgroup filesystem and opens it. It
    then passes that file descriptor to the kernel.

    Example:

    $ perf stat -B -a -e cycles:u,cycles:u,cycles:u -G test1,,test2 -- sleep 1
    Performance counter stats for 'sleep 1':

    2,368,667,414 cycles test1
    2,369,661,459 cycles
    cycles test2

    1.001856890 seconds time elapsed

    Instead of silently building the python binding.

  • 78f7defed   perf annotate: Move annotate functions to util/ ... Browse Code »

    They will be used by perf top, so that we have just one set of routines
    to do annotation.

    Rename "struct sym_priv" to "struct annotation", etc, to clarify this
    code a bit.

    Rename "struct sym_ext" to "struct source_line", to give it a meaningful
    name, that clarifies that it is a the result of an addr2line call, that
    is sorted by percentage one particular source code line appeared in the
    annotation.

    And since we're moving things around also rename 'sym_hist->ip' to
    'sym_hist->addr' as we want to do data structure annotation at some
    point.

  • 877108e42   perf tools: Initial python binding ... Browse Code »

    First clarifying that this kind of binding is not a replacement or an
    equivalent to the 'perf script' way of using python with perf.

    The 'perf script' way is to process events and look at a given script
    for some python function that matches the events to pass each event for
    processing.

    This is a python module, i.e. everything is driven from the python
    script, that merely uses "import perf" or "from perf import".

    perf script is focused on tracepoints, this binding is focused on profiling as
    an initial target. More work is needed to make available tracepoint specific
    variables as event variables accessible via this binding.

    There is one example of such usage model, in
    tools/perf/python/twatch.py, a tool to watch "cycles" events together
    with task (fork, exit) and comm perf events.

    For now, due to me not being able to grok how python distutils cope with
    building C extensions outside the sources dir the install target just
    builds it, I'm using it as:

    [root@emilia linux]# export PYTHONPATH=~acme/git/build/perf/lib.linux-x86_64-2.6/
    [root@emilia linux]# tools/perf/python/twatch.py
    cpu: 4, pid: 30126, tid: 30126 { type: mmap, pid: 30126, tid: 30126, start: 0x4, length: 0x82e9ca03, offset: 0, filename: }
    cpu: 6, pid: 47, tid: 47 { type: mmap, pid: 47, tid: 47, start: 0x6, length: 0xbef87c36, offset: 0, filename: }
    cpu: 1, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0x1, length: 0x775d1904, offset: 0, filename: }
    cpu: 7, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0x7, length: 0xc750aeb6, offset: 0, filename: }
    cpu: 5, pid: 2255, tid: 2255 { type: mmap, pid: 2255, tid: 2255, start: 0x5, length: 0x76669635, offset: 0, filename: }
    cpu: 0, pid: 0, tid: 0 { type: mmap, pid: 0, tid: 0, start: 0, length: 0x6422ef6b, offset: 0, filename: }
    cpu: 2, pid: 2255, tid: 2255 { type: mmap, pid: 2255, tid: 2255, start: 0x2, length: 0xe078757a, offset: 0, filename: }
    cpu: 1, pid: 5769, tid: 5769 { type: fork, pid: 30127, ppid: 5769, tid: 30127, ptid: 5769, time: 103893991270534}
    cpu: 6, pid: 30127, tid: 30127 { type: comm, pid: 30127, tid: 30127, comm: ls }
    cpu: 6, pid: 30127, tid: 30127 { type: exit, pid: 30127, ppid: 30127, tid: 30127, ptid: 30127, time: 103893993273024}

    The first 8 mmap events in this 8 way machine are a mistery that is still being
    investigated.

    More of the tools/perf/util/ APIs will be exposed via this python binding as
    the need arises. For now the focus is on creating events and processing them,
    symbol resolution is an obvious next step, with tracepoint variables as a close
    second step.

  • 68baa431e   perf tools: Add strfilter for general purpose string filter ... Browse Code »

    Add strfilter for general purpose string filter.

    Every filter rules are descrived by glob matching pattern and '!' prefix
    which means Logical NOT.

    A strfilter consists of those filter rules connected with '&' and '|'.

    A set of rules can be folded by using '(' and ')'.

    It also accepts spaces around rules and those operators.

    Format:
    ::= | "!" | | "(" ")"
    ::= "&" | "|"

    e.g.:

    "(add* | del*) & *timer" filter rules pass strings which start with add
    or del and end with timer.

    This will be used by perf probe --filter.

    Changes in V2:
    - Fix to check result of strdup() and strfilter__alloc().
    - Encapsulate and simplify interfaces as like regex(3).
