Pull perf tools updates from Arnaldo Carvalho de Melo:
 "Miscellaneous:

   - Add Ian Rogers to MAINTAINERS as a perf tools reviewer.

   - Add support for retire latency feature (pipeline stall of a
     instruction compared to the previous one, in cycles) present on
     some Intel processors.

   - Add 'perf c2c' report option to show false sharing with adjacent
     cachelines, to be used in machines with cacheline prefetching,
     where accesses to a cacheline brings the next one too.

   - Skip 'perf test bpf' when the required kernel-debuginfo package
     isn't installed.

   - Avoid d3-flame-graph package dependency in 'perf script flamegraph',
     making this feature more generally available.

   - Add JSON metric events to present CPI stall cycles in Power10.

   - Assorted improvements/refactorings on the JSON metrics parsing
     code.

  perf lock contention:

   - Add -o/--lock-owner option:

        $ sudo ./perf lock contention -abo -- ./perf bench sched pipe
        # Running 'sched/pipe' benchmark:
        # Executed 1000000 pipe operations between two processes

     Please note that to have the -b option (BPF) working above one has
     to build with BUILD_BPF_SKEL=1.

   - Add more 'perf test' entries to test these new features.

  perf script:

   - Add 'cgroup' field for 'perf script' output:

        $ perf record --all-cgroups -- true
        $ perf script -F comm,pid,cgroup
                  true 337112  /user.slice/user-657345.slice/user@657345.service/...
                  true 337112  /user.slice/user-657345.slice/user@657345.service/...
                  true 337112  /user.slice/user-657345.slice/user@657345.service/...
                  true 337112  /user.slice/user-657345.slice/user@657345.service/...

   - Add support for showing branch speculation information in 'perf
     script' and in the 'perf report' raw dump (-D).

  perf record:

   - Fix 'perf record' segfault with --overwrite and --max-size.

  perf test/bench:

   - Switch basic BPF filtering test to use syscall tracepoint to avoid
     the variable number of probes inserted when using the previous
     probe point (do_epoll_wait) that happens on different CPU
     architectures.

   - Fix DWARF unwind test by adding non-inline to expected function in
     a backtrace.

   - Use 'grep -c' where the longer form 'grep | wc -l' was being used.

   - Add getpid and execve benchmarks to 'perf bench syscall'.

  Intel PT:

   - Add support for synthesizing "cycle" events from Intel PT traces as
     we support "instruction" events when Intel PT CYC packets are
     available. This enables much more accurate profiles than when using
     the regular 'perf record -e cycles' (the default) when the workload
     lasts for very short periods (<10ms).

   - .plt symbol handling improvements, better handling IBT (in the past
     MPX) done in the context of decoding Intel PT processor traces,
     IFUNC symbols on x86_64, static executables, understanding .plt.got
     symbols on x86_64.

   - Add a 'perf test' to test symbol resolution, part of the .plt
     improvements series, this tests things like symbol size in contexts
     where only the symbol start is available (kallsyms), etc.

   - Better handle auxtrace/Intel PT data when using pipe mode (perf
     record sleep 1|perf report).

   - Fix symbol lookup with kcore with multiple segments match stext,
     getting the symbol resolution to just show DSOs as unknown.

  ARM:

   - Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
     Macrocell v4).

   - Ensure ARM64 CoreSight timestamps don't go backwards.

   - Document that ARM64 SPE (Statistical Profiling Extension) is used
     with 'perf c2c/mem'.

   - Add raw decoding for ARM64 SPEv1.2 previous branch address.

   - Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1,
     TLB, cache, branch, PE utilization and instruction mix metrics.

   - Update decoder code for OpenCSD version 1.4, on ARM64 systems.

   - Fix command line auto-complete of CPU events on aarch64.

  Build:

   - Fix 'perf probe' and 'perf test' when libtraceevent isn't linked,
     as several tests use tracepoints, those should be skipped.

   - More fallout fixes for the removal of tools/lib/traceevent/.

   - Fix build error when linking with libpfm"

+Pipe mode
+---------
+Pipe mode is a problem for Intel PT and possibly other auxtrace users.
+It's not recommended to use a pipe as data output with Intel PT because
+of the following reason.
+
+Essentially the auxtrace buffers do not behave like the regular perf
+event buffers.  That is because the head and tail are updated by
+software, but in the auxtrace case the data is written by hardware.
+So the head and tail do not get updated as data is written.
+
+In the Intel PT case, the head and tail are updated only when the trace
+is disabled by software, for example:
+    - full-trace, system wide : when buffer passes watermark
+    - full-trace, not system-wide : when buffer passes watermark or
+                                    context switches
+    - snapshot mode : as above but also when a snapshot is made
+    - sample mode : as above but also when a sample is made
+
+That means finished-round ordering doesn't work.  An auxtrace buffer
+can turn up that has data that extends back in time, possibly to the
+very beginning of tracing.
+
+For a perf.data file, that problem is solved by going through the trace
+and queuing up the auxtrace buffers in advance.
+
+For pipe mode, the order of events and timestamps can presumably
+be messed up.
