      perf cpumap: Document cpu__get_node() and remove redundant function · 194a3a20
      Ian Rogers authored
      cpu_map__get_node_id() isn't used externally and merely delegates to
      cpu__get_node().

      perf cpumap: Rename empty functions · 51b826fa
      Ian Rogers authored
      Remove cpu_map from name as a cpu_map isn't used. Pass a const pointer
      rather than by value to avoid unnecessary copying.

      perf cpumap: Simplify equal function name · 3ac23d19
      Ian Rogers authored
      Rename cpu_map__compare_aggr_cpu_id() to aggr_cpu_id__equal(), the
      cpu_map part of the name is misleading. Equal better describes the
      function than compare.
      
      Switch to const pointer rather than value as struct given the number of
      variables in aggr_cpu_id().

      perf stat: Correct aggregation CPU map · 01843ca0
      Ian Rogers authored
      Switch the perf_cpu_map in aggr_update_shadow from
      the evlist to the counter's cpu map, so the index is appropriate. This
      addresses a problem where uncore counts, with a cpumap like:
      $ cat /sys/devices/uncore_imc_0/cpumask
      0,18
      Don't aggregate counts in CPUs based on the index of those values in the
      cpumap (0 and 1) but on the actual CPU (0 and 18). Thereby correcting
      metric calculations in per-socket mode for counters without a full
      cpumask.
      
      On a SkylakeX with a tweaked DRAM_BW_Use metric, to remove unnecessary

      perf evsel: Improve error message for uncore events · dcffc5eb
      Ian Rogers authored
      When a group has multiple events and the leader fails it can yield
      errors like:
      
        $ perf stat -e '{uncore_imc/cas_count_read/},instructions' /bin/true
        Error:
        The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (uncore_imc/cas_count_read/).
        /bin/dmesg | grep -i perf may provide additional information.
      
      However, when not the group leader <not supported> is given:
      
        $ perf stat -e '{instructions,uncore_imc/cas_count_read/}' /bin/true
        ...
                 1,619,057      instructions
           <not supported> MiB  uncore_imc/cas_count_read/
      
      This is necessary because get_group_fd will fail if the leader fails and
      is the direct result of the check on line 750 of builtin-stat.c in
      stat_handle_error that returns COUNTER_SKIP for the latter case.
      
      This patch improves the error message to:
      
        $ perf stat -e '{uncore_imc/cas_count_read/},instructions' /bin/true
        Error:
        Invalid event (uncore_imc/cas_count_read/) in per-thread mode, enable system wide with '-a'.
      
      v2. Changed the test to use !target__has_cpu as suggested by Namhyung Kim.

      perf annotate: Avoid TUI crash when navigating in the annotation of recursive functions · d5962fb7
      Dario Petrillo authored
      In 'perf report', entering a recursive function from inside of itself
      (either directly of indirectly through some other function) results in
      calling symbol__annotate2 multiple() times, and freeing the whole
      disassembly when exiting from the innermost instance.
      
      The first issue causes the function's disassembly to be duplicated, and
      the latter a heap use-after-free (and crash) when trying to access the
      disassembly again.
      
      I reproduced the bug on perf 5.11.22 (Ubuntu 20.04.3 LTS) and 5.16.rc8
      with the following testcase (compile with gcc recursive.c -o recursive).
      To reproduce:
      
      - perf record ./recursive
      - perf report
      - enter fibonacci and annotate it
      - move the cursor on one of the "callq fibonacci" instructions and press enter
        - at this point there will be two copies of the function in the disassembly
      - go back by pressing q, and perf will crash
      
        #include <stdio.h>
      
        int fibonacci(int n)
        {
            if(n <= 2) return 1;
            return fibonacci(n-1) + fibonacci(n-2);
        }
      
        int main()
        {
            printf("%d\n", fibonacci(40));
        }
      
      This patch addresses the issue by annotating a function and freeing the
      associated memory on exit only if no annotation is already present, so
      that a recursive function is only annotated on entry.

      perf sort: Include global and local variants for p_stage_cyc sort key · e3304c21
      Athira Rajeev authored
      Sort key 'p_stage_cyc' is used to present the latency cycles spent in
      pipeline stages.
      
      perf has local 'p_stage_cyc' sort key to display this info. There is no
      global variant available for this sort key. The local variant shows
      latency in a single sample, whereas the global value will be useful to
      present the total latency (sum of latencies) in the hist entry. It
      represents the latency number multiplied by the number of samples.
      
      Add global ('p_stage_cyc') and local variant ('local_p_stage_cyc') for
      this sort key. Use 'local_p_stage_cyc' as default option for "mem" sort
      mode.
      
      Also add this to the list of dynamic sort keys and made the
      "dynamic_headers" and "arch_specific_sort_keys" as static.
