1Perf-Trace-Util version 0.01
2============================
3
4This module contains utility functions for use with perf trace.
5
6Core.pm and Util.pm are pure Perl modules; Core.pm contains routines
7that the core perf support for Perl calls on and should always be
8'used', while Util.pm contains useful but optional utility functions
9that scripts may want to use. Context.pm contains the Perl->C
10interface that allows scripts to access data in the embedding perf
11executable; scripts wishing to do that should 'use Context.pm'.
12
13The Perl->C perf interface is completely driven by Context.xs. If you
14want to add new Perl functions that end up accessing C data in the
15perf executable, you add desciptions of the new functions here.
16scripting_context is a pointer to the perf data in the perf executable
17that you want to access - it's passed as the second parameter,
18$context, to all handler functions.
19
20After you do that:
21
22 perl Makefile.PL # to create a Makefile for the next step
23 make # to create Context.c
24
25 edit Context.c to add const to the char* file = __FILE__ line in
26 XS(boot_Perf__Trace__Context) to silence a warning/error.
27
28 You can delete the Makefile, object files and anything else that was
29 generated e.g. blib and shared library, etc, except for of course
30 Context.c
31
32 You should then be able to run the normal perf make as usual.
33
34INSTALLATION
35
36Building perf with perf trace Perl scripting should install this
37module in the right place.
38
39You should make sure libperl and ExtUtils/Embed.pm are installed first
40e.g. apt-get install libperl-dev or yum install perl-ExtUtils-Embed.
