 tagger Arnaldo Carvalho de Melo <acme@redhat.com> 1630780104 -0300
 
 perf tools changes for v5.15:
 
 New features:
 
 - Improvements for the flamegraph python script, including:
 
   - Display perf.data header
   - Display PIDs of user stacks
   - Added option to change color scheme
   - Default to blue/green color scheme to improve accessibility
   - Correctly identify kernel stacks when debuginfo is available
 
 - Improvements for 'perf bench futex':
   - Add --mlockall parameter
   - Add --broadcast and --pi to the 'requeue' sub benchmark
 
 - Add support for PMU aliases.
 
 - Introduce an ARM Coresight ETE decoder.
 
 - Add a 'perf bench' entry for evlist open/close operations, to help quantify
   improvements with multithreading 'perf record'.
 
 - Allow reporting the [un]throttle PERF_RECORD_ meta event in 'perf script's
   python scripting.
 
 - Add a 'perf test' entry for PMU aliases.
 
 - Add a 'perf test' entry for 'perf record/perf report/perf script' pipe mode.
 
 Fixes:
 
 - perf script dlfilter (API for filtering via dynamically loaded shared object
   introduced in v5.14) fixes and a 'perf test' entry for it.
 
 - Fix get_current_dir_name() compilation on Android.
 
 - Fix issues with asciidoc and double dashes uses.
 
 - Fix memory leaks in the BTF handling code.
 
 - Fix leftover problems in the Documentation from the infrastructure originally
   lifted from the git codebase.
 
 - Fix *probe_vfs_getname.sh 'perf test' failures.
 
 - Handle fd gaps in 'perf test's test__dso_data_reopen().
 
 - Make sure to show disasembly warnings for 'perf annotate --stdio'.
 
 - Fix output from pipe to file and vice-versa in 'perf record/report/script'.
 
 - Correct 'perf data -h' output.
 
 - Fix wrong comm in system-wide mode with 'perf record --delay'.
 
 - Do not allow --for-each-cgroup without cpu in 'perf stat'
 
 - Make 'perf test --skip' work on shell tests.
 
 - Fix libperf's verbose printing.
 
 Misc improvements:
 
 - Preparatory patches for multithreading varios 'perf record' phases
   (synthesizing, opening, recording, etc).
 
 - Add sparse context/locking annotations in compiler-types.h, also to help with
   the multithreading effort.
 
 - Optimize the generation of the arch specific erno tables used in 'perf trace'.
 
 - Optimize libperf's perf_cpu_map__max().
 
 - Improve ARM's CoreSight warnings.
 
 - Report collisions in AUX records.
 
 - Improve warnings for the LLVM 'perf test' entry.
 
 - Improve the PMU events 'perf test' codebase.
 
 - perf test: Do not compare overheads in the zstd comp test
 
 - Better support annotation on ARM.
 
 - Update 'perf trace's cmd string table to decode sys_bpf() first arg.
 
 Vendor events:
 
 - Add JSON events and metrics for Intel's Ice Lake, Tiger Lake and Elhart Lake.
 
 - Update JSON eventsand metrics for Intel's Cascade Lake and Sky Lake servers.
 
 Hardware tracing:
 
 - Improvements for the ARM hardware tracing auxtrace support.
