      perf: make perf stat print user provided full event names · f0c55bcf
      Stephane Eranian authored
      
      
      This patch changes the way perf stat prints event names at the end of a
      run. Until now, it was trying to reconstruct the event name from its
      encoding. The problem is that it would only print generic events without
      their modifiers (u, k, pp).
      
      This patch saves the event name as passed by the user in the evsel
      struct and uses it to print the final event name.
      
      This would also work in case perf is linked with a library (such as
      libpfm4) which provides full PMU event tables.
      
      $ perf stat -e cycles:u,cycles:k date

      perf python: Add cgroup.c to setup.py to get it building again · 4498062e
      Arnaldo Carvalho de Melo authored
      The 023695d9
      
       cset added a new file, util/cgroup.c, that is referenced from
      util/evsel.c, so it needs to be present in util/setup.py so that the python
      shared object binding works, fixing this:
      
      [root@emilia linux]# export PYTHONPATH=~acme/git/build/perf/python/
      [root@emilia linux]# ./tools/perf/python/twatch.py
      Traceback (most recent call last):
        File "./tools/perf/python/twatch.py", line 16, in <module>
          import perf
      ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: close_cgroup
