Perf-Trace-Util version 0.01
|
|
============================
|
|
|
|
This module contains utility functions for use with perf trace.
|
|
|
|
Core.pm and Util.pm are pure Perl modules; Core.pm contains routines
|
|
that the core perf support for Perl calls on and should always be
|
|
'used', while Util.pm contains useful but optional utility functions
|
|
that scripts may want to use. Context.pm contains the Perl->C
|
|
interface that allows scripts to access data in the embedding perf
|
|
executable; scripts wishing to do that should 'use Context.pm'.
|
|
|
|
The Perl->C perf interface is completely driven by Context.xs. If you
|
|
want to add new Perl functions that end up accessing C data in the
|
|
perf executable, you add desciptions of the new functions here.
|
|
scripting_context is a pointer to the perf data in the perf executable
|
|
that you want to access - it's passed as the second parameter,
|
|
$context, to all handler functions.
|
|
|
|
After you do that:
|
|
|
|
perl Makefile.PL # to create a Makefile for the next step
|
|
make # to create Context.c
|
|
|
|
edit Context.c to add const to the char* file = __FILE__ line in
|
|
XS(boot_Perf__Trace__Context) to silence a warning/error.
|
|
|
|
You can delete the Makefile, object files and anything else that was
|
|
generated e.g. blib and shared library, etc, except for of course
|
|
Context.c
|
|
|
|
You should then be able to run the normal perf make as usual.
|
|
|
|
INSTALLATION
|
|
|
|
Building perf with perf trace Perl scripting should install this
|
|
module in the right place.
|
|
|
|
You should make sure libperl and ExtUtils/Embed.pm are installed first
|
|
e.g. apt-get install libperl-dev or yum install perl-ExtUtils-Embed.
