      perf session: Remove last reference to hists struct · 2a1731fb
      Arnaldo Carvalho de Melo 提交于
      Now perf_session doesn't require that the evsels in its evlist are hists
      containing ones.
      
      Tools that are hists based and want to do per evsel events_stats
      updates, if at some point this turns into a necessity, should do it in
      the tool specific code, keeping the session class hists agnostic.

      PERF_RECORD_SAMPLE was not being counted here and is the only per-evsel
      thing anyway, the other events were not mapping to a evsel.
      
      With this we don't require that evsels used with a perf_session need to
      have space for hists, like the ones in annotate, report, top.

      mm/balloon_compaction: add vmstat counters and kpageflags bit · 09316c09
      Konstantin Khlebnikov 提交于
      Always mark pages with PageBalloon even if balloon compaction is disabled
      and expose this mark in /proc/kpageflags as KPF_BALLOON.
      
      Also this patch adds three counters into /proc/vmstat: "balloon_inflate",
      "balloon_deflate" and "balloon_migrate".  They accumulate balloon
      activity.  Current size of balloon is (balloon_inflate - balloon_deflate)
      pages.
      
      All generic balloon code now gathered under option CONFIG_MEMORY_BALLOON.
      It should be selected by ballooning driver which wants use this feature.
      Currently virtio-balloon is the only user.

      Not all tools need a hists instance per perf_evsel, so lets pave the way
      to remove evsel->hists while leaving a way to access the hists from a

      lives the evsel.

      ftracetest: Add POSIX.3 standard and XFAIL result codes · 915de2ad
      Masami Hiramatsu 提交于
      Add XFAIL and POSIX 1003.3 standard codes (UNRESOLVED/
      UNTESTED/UNSUPPORTED) as result codes. These are used for the
      results that test case is expected to fail or unsupported
      feature (by config).
      
      To return these result code, this introduces exit_unresolved,
      exit_untested, exit_unsupported and exit_xfail functions,
      which use real-time signals to notify the result code to
      ftracetest.
      
      This also set "errexit" option for the testcases, so that
      the tests don't need to exit explicitly.
      
      Note that if the test returns UNRESOLVED/UNSUPPORTED/FAIL,
      its test log including executed commands is shown on console
      and main logfile as below.
