Perf-Trace-Util version 0.01 ============================ This module contains utility functions for use with perf script. 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 script 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.

nvdimm: constify device_type structures
Declare device_type structure as const as it is only stored in the type field of a device structure. This field is of type const, so add const to declaration of device_type structure.
