      libperf: Add arm64 support to perf_mmap__read_self() · 407eb43a
      Rob Herring authored
      Add the arm64 variants for read_perf_counter() and read_timestamp().
      Unfortunately the counter number is encoded into the instruction, so the
      code is a bit verbose to enumerate all possible counters.

        06feec60 ("ASoC: hdmi-codec: Fix OOB memory accesses")
      
      Which entails no changes in the tooling side as it doesn't introduce new
      SNDRV_PCM_IOCTL_ ioctls.
      
      To silence this perf tools build warning:

      perf stat: Fix display of grouped aliased events · b2b1aa73
      Ian Rogers authored
      An event may have a number of uncore aliases that when added to the
      evlist are consecutive.
      
      If there are multiple uncore events in a group then
      parse_events__set_leader_for_uncore_aliase will reorder the evlist so
      that events on the same PMU are adjacent.
      
      The collect_all_aliases function assumes that aliases are in blocks so
      that only the first counter is printed and all others are marked merged.
      
      The reordering for groups breaks the assumption and so all counts are
      printed.
      
      This change removes the assumption from collect_all_aliases
      that the events are in blocks and instead processes the entire evlist.
      
      Before:
      
        ```
        $ perf stat -e '{UNC_CHA_TOR_OCCUPANCY.IA_MISS_DRD_REMOTE,UNC_CHA_TOR_INSERTS.IA_MISS_DRD_REMOTE},duration_time' -a -A -- sleep 1

      perf tools: Apply correct label to user/kernel symbols in branch mode · 05b5a9d6
      German Gomez authored
      In branch mode, the branch symbols were being displayed with incorrect
      cpumode labels. So fix this.
      
      For example, before:

        # perf report -b
      
        Overhead  Command  Source Shared Object  Source Symbol               Target Symbol

      perf synthetic-events: Return error if procfs isn't mounted for PID namespaces · bc9c806e
      Leo Yan authored
      For perf recording, it retrieves process info by iterating nodes in proc
      fs.  If we run perf in a non-root PID namespace with command:
      
        # unshare --fork --pid perf record -e cycles -a -- test_program
      
      ... in this case, unshare command creates a child PID namespace and
      launches perf tool in it, but the issue is the proc fs is not mounted
      for the non-root PID namespace, this leads to the perf tool gathering
      process info from its parent PID namespace.
      
      We can use below command to observe the process nodes under proc fs:
      
        # unshare --pid --fork ls /proc

      So it shows many existed tasks, since unshared command has not mounted
      the proc fs for the new created PID namespace, it still accesses the
      proc fs of the root PID namespace.  This leads to two prominent issues:
      
      - Firstly, PID values are mismatched between thread info and samples.
        The gathered thread info are coming from the proc fs of the root PID
        namespace, but samples record its PID from the child PID namespace.
      
      - The second issue is profiled program 'test_program' returns its forked
        PID number from the child PID namespace, perf tool wrongly uses this
        PID number to retrieve the process info via the proc fs of the root
        PID namespace.
      
      To avoid issues, we need to mount proc fs for the child PID namespace
      with the option '--mount-proc' when use unshare command:
      
        # unshare --fork --pid --mount-proc perf record -e cycles -a -- test_program
      
      Conversely, when the proc fs of the root PID namespace is used by child
      namespace, perf tool can detect the multiple PID levels and
      nsinfo__is_in_root_namespace() returns false, this patch reports error
      for this case:
      
        # unshare --fork --pid perf record -e cycles -a -- test_program
        Couldn't synthesize bpf events.
        Perf runs in non-root PID namespace but it tries to gather process info from its parent PID namespace.
        Please mount the proc file system properly, e.g. add the option '--mount-proc' for unshare command.

      This is also by now used by tools/testing/selftests/kvm/, a simple test
