[RFC,v3,0/3] trace-cruncher: Initial support for perf

Message

Tzvetomir Stoyanov (VMware) April 15, 2022, 11:41 a.m. UTC

Two major functionalities are introduced by this patch set:
 - VMA <-> function name resolving, using bfd library.
 - Support for Linux kernel perf framework, using perf library.

v3 changes:
 - Renamed some of the methods, to be consistent with the trace-cruncher
   naming convention.
 - Coding style fixes.
 - Code clean ups.
	
v2 changes:
 - Renamed a lot of APIs and internal functions, to have more consistent
   names and prefixes.
 - Added support for staring an application that is going to be traced.
 - Added support for setting the time duration of collecting the traces.
 - Handle ctrl-c into the C library instead of the user application.
 - Coding style fixes.
