      perf report: Add srcline_from/to branch sort keys · 508be0df
      Andi Kleen 提交于
      Add "srcline_from" and "srcline_to" branch sort keys that allow to show
      the source lines of a branch.
      
      That makes it much easier to track down where particular branches happen
      in the program, for example to examine branch mispredictions, or to
      associate it with cycle counts:
      
        % perf record -b -e cycles:p ./tcall
        % perf report --sort srcline_from,srcline_to,mispredict
        ...

      perf tools: Separate accounting of contexts and real addresses in a stack trace · a29d5c9b
      Arnaldo Carvalho de Melo 提交于
      The perf_sample->ip_callchain->nr value includes all the entries in the
      ip_callchain->ip[] array, real addresses and PERF_CONTEXT_{KERNEL,USER,etc},
      while what the user expects is that what is in the kernel.perf_event_max_stack
      sysctl or in the upcoming per event perf_event_attr.sample_max_stack knob be
      honoured in terms of IP addresses in the stack trace.
      
      So match the kernel support and validate chain->nr taking into account
      both kernel.perf_event_max_stack and kernel.perf_event_max_contexts_per_stack.

      A new sysctl, kernel.perf_event_max_contexts_per_stack is also
      introduced for investigating possible bugs in the callchain

      perf core: Add a 'nr' field to perf_event_callchain_context · 3b1fff08
      Arnaldo Carvalho de Melo 提交于
      We will use it to count how many addresses are in the entry->ip[] array,
      excluding PERF_CONTEXT_{KERNEL,USER,etc} entries, so that we can really
      return the number of entries specified by the user via the relevant
      sysctl, kernel.perf_event_max_contexts, or via the per event
      perf_event_attr.sample_max_stack knob.
      
      This way we keep the perf_sample->ip_callchain->nr meaning, that is the
      number of entries, be it real addresses or PERF_CONTEXT_ entries, while
      honouring the max_stack knobs, i.e. the end result will be max_stack
      entries if we have at least that many entries in a given stack trace.

      In all those cases we can only change the value if there are no perf

      perf stat: Use cpu-clock event for cpu targets · a1f3d567
      Namhyung Kim 提交于
      Currently 'perf stat' always counts task-clock event by default.  But
      it's somewhat confusing for system-wide targets (especially with 'sleep
      N' as the 'sleep' task just sleeps and doesn't use cputime).  Changing
      to cpu-clock event instead for that case makes more sense IMHO.

      perf symbols: Store vdso buildid unconditionally · 6ae98ba6
      He Kuang 提交于
      When unwinding callchains on a different machine, vdso info should be
      available so the unwind process won't be interrupted if address falls
      into vdso region. But in most cases, the addresses of sample events are
      not in vdso range, the buildid of a zero hit vdso won't be stored into
      perf.data.
      
      This patch stores vdso buildid regardless of whether the vdso is hit or
      not.

      perf stat: Avoid fractional digits for integer scales · e3b03b6c
      Andi Kleen 提交于
      When the scaling factor is a full integer don't display fractional
      digits. This avoids unnecessary .00 output for topdown metrics with
      scale factors.
      
      v2: Remove redundant check.
