perf python scripting: Append examples to err msg about audit-libs-python

2016-02-12T14:30:27+00:00

To print syscall names, the audit-libs-python package is required.. If
not installed, it prints this error string:

    # perf script syscall-counts
    Install the audit-libs-python package to get syscall names.

But the package name is different in Ubuntu, mention that in the error
message, similar to a error message of util/trace-event-scripting.c:

    # perf script syscall-counts
    Install the audit-libs-python package to get syscall names.
    For example:
      # apt-get install python-audit (Ubuntu)
      # yum install audit-libs-python (Fedora)
      etc.

perf script: Add callchain to generic and tracepoint events

This provides valuable information for tracing performance problems.

Since this change alters the interface for the python scripts, also
adjust the script generation and the provided scripts.

perf tools: Finish the removal of 'self' arguments

2013-11-05T18:32:36+00:00

They convey no information, perhaps I was bitten by some snake at some
point, complete the detox by naming the last of those arguments more
sensibly.

perf scripts python: Add a python library EventClass.py

2012-08-08T15:53:08+00:00

This library defines several class types for perf events which could
help to better analyze the event samples. Currently there are just a few
classes, PerfEvent is the base class for all perf events,  PebsEvent is
a HW base Intel x86 PEBS event, and user could add more SW/HW event
classes based on requriements.
