1 Perf-Trace-Util version 0.01 2 ============================ 3 4 This module contains utility functions for use with perf script. 5 6 Core.pm and Util.pm are pure Perl modules; Core.pm contains routines 7 that the core perf support for Perl calls on and should always be 8 'used', while Util.pm contains useful but optional utility functions 9 that scripts may want to use. Context.pm contains the Perl->C 10 interface that allows scripts to access data in the embedding perf 11 executable; scripts wishing to do that should 'use Context.pm'. 12 13 The Perl->C perf interface is completely driven by Context.xs. If you 14 want to add new Perl functions that end up accessing C data in the 15 perf executable, you add desciptions of the new functions here. 16 scripting_context is a pointer to the perf data in the perf executable 17 that you want to access - it's passed as the second parameter, 18 $context, to all handler functions. 19 20 After 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 34 INSTALLATION 35 36 Building perf with perf script Perl scripting should install this 37 module in the right place. 38 39 You should make sure libperl and ExtUtils/Embed.pm are installed first 40 e.g. apt-get install libperl-dev or yum install perl-ExtUtils-Embed. 41 42 DEPENDENCIES 43 44 This module requires these other modules and libraries: 45 46 None 47 48 COPYRIGHT AND LICENCE 49 50 Copyright (C) 2009 by Tom Zanussi <tzanussi (a] gmail.com> 51 52 This library is free software; you can redistribute it and/or modify 53 it under the same terms as Perl itself, either Perl version 5.10.0 or, 54 at your option, any later version of Perl 5 you may have available. 55 56 Alternatively, this software may be distributed under the terms of the 57 GNU General Public License ("GPL") version 2 as published by the Free 58 Software Foundation. 59 60
