perf tools changes for v5.15:

Browse Source 
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.

NOTES
-----
The dlfilter .so file will be dependent on shared libraries. If those change,
it may be necessary to rebuild the .so. Also there may be unexpected results
if the .so uses different versions of the shared libraries that perf uses.
Versions can be checked using the ldd command.

Following those are the 'event handler' functions generated one for
every event in the 'perf record' output. The handler functions take
the form subsystem__event_name, and contain named parameters, one for
the form subsystem\__event_name, and contain named parameters, one for
each field in the event; in this case, there's only one event,
raw_syscalls__sys_enter(). (see the EVENT HANDLERS section below for
more info on event handlers).

SBD-to-MITE switch true penalty cycles happen after the merge mux (MM) receives Decode Stream Buffer (DSB) Sync-indication until receiving the first MITE uop. MM is placed before Instruction Decode Queue (IDQ) to merge uops being fed from the MITE and Decode Stream Buffer (DSB) paths. Decode Stream Buffer (DSB) inserts the Sync-indication whenever a Decode Stream Buffer (DSB)-to-MITE switch occurs.Penalty: A Decode Stream Buffer (DSB) hit followed by a Decode Stream Buffer (DSB) miss can cost up to six cycles in which no uops are delivered to the IDQ.
