      perf tools: Fix perf_event.h header usage · d030260a
      Stephane Eranian authored
      
      
      This patch fixes the usage of the perf_event.h header file
      between command modules and the supporting code in util.
      
      It is necessary to ensure that ALL files use the SAME
      perf_event.h header from the kernel source tree.
      
      There were a couple of #include <linux/perf_event.h> mixed
      with #include "../../perf_event.h".
      
      This caused issues on some distros because of mismatch
      in the layout of struct perf_event_attr. That eventually
      led perf stat to segfault.

      perf evsel: Introduce per cpu and per thread open helpers · 48290609
      Arnaldo Carvalho de Melo authored
      
      
      Abstracting away the loops needed to create the various event fd handlers.
      
      The users have to pass a confiruged perf->evsel.attr field, which is already
      usable after perf_evsel__new (constructor) time, using defaults.
      
      Comes out of the ad-hoc routines in builtin-stat, that now uses it.
      
      Fixed a small silly bug where we were die()ing before killing our
      children, dysfunctional family this one 8-)

      perf evsel: Steal the counter reading routines from stat · c52b12ed

      Making them hopefully generic enough to be used in 'perf test',
      well see.

      Out of ad-hoc code and global arrays with hard coded sizes.
      
      This is the first step on having a library that will be first
      used on regression tests in the 'perf test' tool.
