----------------------------------------------------------------
perf tools changes for v6.7

Build
-----
* Compile BPF programs by default if clang (>= 12.0.1) is available to
  enable more features like kernel lock contention, off-cpu profiling,
  kwork, sample filtering and so on.  It can be disabled by passing
  BUILD_BPF_SKEL=0 to make.

* Produce better error messages for bison on debug build (make DEBUG=1)
  by defining YYDEBUG symbol internally.

perf record
-----------
* Track sideband events (like FORK/MMAP) from all CPUs even if perf record
  targets a subset of CPUs only (using -C option).  Otherwise it may lose
  some information happened on a CPU out of the target list.

* Fix checking raw sched_switch tracepoint argument using system BTF.
  This affects off-cpu profiling which attaches a BPF program to the raw
  tracepoint.

perf lock contention
--------------------
* Add --lock-cgroup option to see contention by cgroups.  This should be
  used with BPF only (using -b option).

    $ sudo perf lock con -ab --lock-cgroup -- sleep 1
     contended   total wait     max wait     avg wait   cgroup

           835     14.06 ms     41.19 us     16.83 us   /system.slice/led.service
            25    122.38 us     13.77 us      4.89 us   /
            44     23.73 us      3.87 us       539 ns   /user.slice/user-657345.slice/session-c4.scope
             1       491 ns       491 ns       491 ns   /system.slice/connectd.service

* Add -G/--cgroup-filter option to see contention only for given cgroups.
  This can be useful when you identified a cgroup in the above command and
  want to investigate more on it.  It also works with other output options
  like -t/--threads and -l/--lock-addr.

    $ sudo perf lock con -ab -G /user.slice/user-657345.slice/session-c4.scope -- sleep 1
     contended   total wait     max wait     avg wait         type   caller

             8     77.11 us     17.98 us      9.64 us     spinlock   futex_wake+0xc8
             2     24.56 us     14.66 us     12.28 us     spinlock   tick_do_update_jiffies64+0x25
             1      4.97 us      4.97 us      4.97 us     spinlock   futex_q_lock+0x2a

* Use per-cpu array for better spinlock tracking.  This is to improve
  performance of the BPF program and to avoid nested contention on a lock
  in the BPF hash map.

* Update callstack check for PowerPC.  To find a representative caller of a
  lock, it needs to look up the call stacks.  It ends the lookup when it sees
  0 in the call stack buffer.  However, PowerPC call stacks can have 0 values
  in the beginning so skip them when it expects valid call stacks after.

perf kwork
----------
* Support 'sched' class (for -k option) so that it can see task scheduling
  event (using sched_switch tracepoint) as well as irq and workqueue items.

* Add perf kwork top subcommand to show more accurate cpu utilization with
  sched class above.  It works both with a recorded data (using perf kwork
  record command) and BPF (using -b option).  Unlike perf top command, it
  does not support interactive mode (yet).

    $ sudo perf kwork top -b -k sched

    <SNIP>

perf bench
----------
* Add -G/--cgroups option to perf bench sched pipe.  The pipe bench is
  good to measure context switch overhead.  With this option, it puts
  the reader and writer tasks in separate cgroups to enforce context
  switch between two different cgroups.

  Also it needs to set CPU affinity of the tasks in a CPU to accurately
  measure the impact of cgroup context switches.

    $ sudo perf stat -e context-switches,cgroup-switches -- \
    > taskset -c 0 perf bench sched pipe -l 100000
    # Running 'sched/pipe' benchmark:
    # Executed 100000 pipe operations between two processes

         Total time: 0.307 [sec]

           3.078180 usecs/op
             324867 ops/sec

     Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000':

               200,026      context-switches
                    63      cgroup-switches

           0.321637922 seconds time elapsed

  You can see small number of cgroup-switches because both write and read
  tasks are in the same cgroup.

    $ sudo mkdir /sys/fs/cgroup/{AAA,BBB}

    $ sudo perf stat -e context-switches,cgroup-switches -- \
    > taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB
    # Running 'sched/pipe' benchmark:
    # Executed 100000 pipe operations between two processes

         Total time: 0.351 [sec]

           3.512990 usecs/op
             284657 ops/sec

     Performance counter stats for 'taskset -c 0 perf bench sched pipe -l 100000 -G AAA,BBB':

               200,020      context-switches
               200,019      cgroup-switches

           0.365034567 seconds time elapsed

  Now context-switches and cgroup-switches are almost same.  And you can
  see the pipe operation took little more.

* Kill child processes when perf bench sched messaging exited abnormally.
  Otherwise it'd leave the child doing unnecessary work.

perf test
---------
* Fix various shellcheck issues on the tests written in shell script.

* Skip tests when condition is not satisfied:
  - object code reading test for non-text section addresses.
  - CoreSight test if cs_etm// event is not available.
  - lock contention test if not enough CPUs.

Event parsing
-------------
* Make PMU alias name loading lazy to reduce the startup time in the
  event parsing code for perf record, stat and others in the general
  case.

* Lazily compute PMU default config.  In the same sense, delay PMU
  initialization until it's really needed to reduce the startup cost.

* Fix event term values that are raw events.  The event specification
  can have several terms including event name.  But sometimes it clashes
  with raw event encoding which starts with 'r' and has hex-digits.

  For example, an event named 'read' should be processed as a normal
  event but it was mis-treated as a raw encoding and caused a failure.

    $ perf stat -e 'uncore_imc_free_running/event=read/' -a sleep 1
    event syntax error: '..nning/event=read/'
                                      \___ parser error
    Run 'perf list' for a list of valid events

     Usage: perf stat [<options>] [<command>]

        -e, --event <event> event selector. use 'perf list' to list available events

Event metrics
-------------
* Add "Compat" regex to match event with multiple identifiers.

* Usual updates for Intel, Power10, Arm telemetry/CMN and AmpereOne.

Misc
----
* Assorted memory leak fixes and footprint reduction.

* Add "bpf_skeletons" to perf version --build-options so that users can
  check whether their perf tools have BPF support easily.

* Fix unaligned access in Intel-PT packet decoder found by undefined-behavior
  sanitizer.

* Avoid frequency mode for the dummy event.  Surprisingly it'd impact
  kernel timer tick handler performance by force iterating all PMU events.

* Update bash shell completion for events and metrics.
