#     Pull perf tools updates from Namhyung Kim:
#      "Build:
#     
#        - Build each directory as a library so that depedency check for the
#          python extension module can be automatic
#     
#        - Use pkg-config to check libtraceevent and libtracefs
#     
#       perf sched:
#     
#        - Add --task-name and --fuzzy-name options for `perf sched map`
#     
#          It focuses on selected tasks only by removing unrelated tasks in
#          the output. It matches the task comm with the given string and the
#          --fuzzy-name option allows the partial matching:
#     
#            $ sudo perf sched record -a sleep 1
#     
#            $ sudo perf sched map --task-name kworker --fuzzy-name

#     
#        - Fix -r/--repeat option of perf sched replay
#     
#          The documentation said -1 will work as infinity but it didn't
#          accept the value. Update the code and document to use 0 instead
#     
#        - Fix perf sched timehist to account the delay time for preempted
#          tasks
#     
#       Perf event filtering:
#     
#        - perf top gained filtering support on regular events using BPF like
#          perf record. Previously it was able to use it for tracepoints only
#     
#        - The BPF filter now supports filtering by UID/GID. This should be
#          preferred than -u <UID> option as it's racy to scan /proc to check
#          tasks for the user and fails to open an event for the task if it's
#          already gone
#     
#            $ sudo perf top -e cycles --filter "uid == $(id -u)"
#     
#       perf report:
#     
#        - Skip dummy events in the group output by default. The --skip-empty
#          option controls display of empty events without samples. But perf
#          report can force display all events in a group
#     
#          In this case, auto-added a dummy event (for a system-wide record)
#          ends up in the output. Now it can skip those empty events even in
#          the group display mode
#     
#          To preserve the old behavior, run this:
#     
#            $ perf report --group --no-skip-empty
#     
#       perf stat:
#     
#        - Choose the most disaggregate option when multiple aggregation
#          options are given. It used to pick the last option in the command
#          line but it can be confusing and not consistent. Now it'll choose
#          the smallest unit
#     
#          For example, it'd aggregate the result per-core when the user gave
#          both --per-socket and --per-core options at the same time
#     
#       Internals:
#     
#        - Fix `perf bench` when some CPUs are offline
#     
#        - Fix handling of JIT symbol mappings to accept "/tmp/perf-${PID}.map
#          patterns only so that it can not be confused by other /tmp/perf-*
#          files
#     
#        - Many improvements and fixes for `perf test`
#     
#       Others:
#     
#        - Support some new instructions for Intel-PT
#     
#        - Fix syscall ID mapping in perf trace
#     
#        - Document AMD IBS PMU usages
#     
#        - Change `perf lock info` to show map and thread info by default
#     
#       Vendor JSON events:
#     
#        - Update Intel events and metrics
#     
#        - Add i.MX9[35] DDR metrics"
