perf lock:

- Add -c/--combine-locks option to merge lock instances in the same
class into a single entry.

- Add --synth=no option for record, as there is no need to symbolize,
lock names comes from the tracepoints.

perf record:

- Threaded recording, opt-in, via the new --threads command line
option.

- Improve AMD IBS (Instruction-Based Sampling) error handling
messages.

perf script:

- Add 'brstackinsnlen' field (use it with -F) for branch stacks.

- Output branch sample type in 'perf script'.

perf report:

- Add "addr_from" and "addr_to" sort dimensions.

- Print branch stack entry type in 'perf report --dump-raw-trace'

- Fix symbolization for chrooted workloads.

Hardware tracing:

Intel PT:

- Add CFE (Control Flow Event) and EVD (Event Data) packets support.

- Add MODE.Exec IFLAG bit support.

Explanation about these features from the "Intel® 64 and IA-32
architectures software developer’s manual combined volumes: 1, 2A,
2B, 2C, 2D, 3A, 3B, 3C, 3D, and 4" PDF at:

https://cdrdv2.intel.com/v1/dl/getContent/671200

At page 3951:
"32.2.4

Event Trace is a capability that exposes details about the
asynchronous events, when they are generated, and when their
corresponding software event handler completes execution. These
include:

o Interrupts, including NMI and SMI, including the interrupt
vector when defined.

o Faults, exceptions including the fault vector.

- Page faults additionally include the page fault address,
when in context.

o Event handler returns, including IRET and RSM.

o VM exits and VM entries.¹

- VM exits include the values written to the “exit reason”
and “exit qualification” VMCS fields. INIT and SIPI events.

o TSX aborts, including the abort status returned for the RTM
instructions.

o Shutdown.

Additionally, it provides indication of the status of the
Interrupt Flag (IF), to indicate when interrupts are masked"

ARM CoreSight:

- Use advertised caps/min_interval as default sample_period on ARM
spe.

- Update deduction of TRCCONFIGR register for branch broadcast on
ARM's CoreSight ETM.

Vendor Events (JSON):

Intel:

- Update events and metrics for: Alderlake, Broadwell, Broadwell DE,
BroadwellX, CascadelakeX, Elkhartlake, Bonnell, Goldmont,
GoldmontPlus, Westmere EP-DP, Haswell, HaswellX, Icelake, IcelakeX,
Ivybridge, Ivytown, Jaketown, Knights Landing, Nehalem EP,
Sandybridge, Silvermont, Skylake, Skylake Server, SkylakeX,
Tigerlake, TremontX, Westmere EP-SP, and Westmere EX.

ARM:

- Add support for HiSilicon CPA PMU aliasing.

perf stat:

- Fix forked applications enablement of counters.

- The 'slots' should only be printed on a different order than the
one specified on the command line when 'topdown' events are
present, fix it.

Miscellaneous:

- Sync msr-index, cpufeatures header files with the kernel sources.

- Stop using some deprecated libbpf APIs in 'perf trace'.

- Fix some spelling mistakes.

- Refactor the maps pointers usage to pave the way for using refcount
debugging.

- Only offer the --tui option on perf top, report and annotate when
perf was built with libslang.

- Don't mention --to-ctf in 'perf data --help' when not linking with
the required library, libbabeltrace.

- Use ARRAY_SIZE() instead of ad hoc equivalent, spotted by
array_size.cocci.

- Enhance the matching of sub-commands abbreviations:
'perf c2c rec' -> 'perf c2c record'
'perf c2c recport -> error

- Set build-id using build-id header on new mmap records.

- Fix generation of 'perf --version' string.

perf test:

- Add test for the arm_spe event.

- Add test to check unwinding using fame-pointer (fp) mode on arm64.

- Make metric testing more robust in 'perf test'.

- Add error message for unsupported branch stack cases.

libperf:

- Add API for allocating new thread map array.

- Fix typo in perf_evlist__open() failure error messages in libperf
tests.

perf c2c:

- Replace bitmap_weight() with bitmap_empty() where appropriate"
