Merge tag 'perf-tools-for-v6.10-1-2024-05-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

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

- Integrate the shellcheck utility with the build of perf to allow
catching shell problems early in areas such as 'perf test', 'perf
trace' scrape scripts, etc

- Add 'uretprobe' variant in the 'perf bench uprobe' tool

- Add script to run instances of 'perf script' in parallel

- Allow parsing tracepoint names that start with digits, such as
9p/9p_client_req, etc. Make sure 'perf test' tests it even on
systems where those tracepoints aren't available

- Add Kan Liang to MAINTAINERS as a perf tools reviewer

- Add support for using the 'capstone' disassembler library in
various tools, such as 'perf script' and 'perf annotate'. This is
an alternative for the use of the 'xed' and 'objdump' disassemblers

Data-type profiling improvements:

- Resolve types for a->b->c by backtracking the assignments until it
finds DWARF info for one of those members

- Support for global variables, keeping a cache to speed up lookups

- Handle the 'call' instruction, dealing with effects on registers
and handling its return when tracking register data types

- Handle x86's segment based addressing like %gs:0x28, to support
things like per CPU variables, the stack canary, etc

- Data-type profiling got big speedups when using capstone for
disassembling. The objdump outoput parsing method is left as a
fallback when capstone fails or isn't available. There are patches
posted for 6.11 that to use a LLVM disassembler

- Support event group display in the TUI when annotating types with
--data-type, for instance to show memory load and store events for
the data type fields

- Optimize the 'perf annotate' data structures, reducing memory usage

- Add a initial 'perf test' for 'perf annotate', checking that a
target symbol appears on the output, specifying objdump via the
command line, etc

Vendor Events:

- Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand
Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra
Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics
erroneously in TopdownL1

- Add AMD's Zen 5 core and uncore events and metrics. Those come from
the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh
Processors" document, with events that capture information on op
dispatch, execution and retirement, branch prediction, L1 and L2
cache activity, TLB activity, etc

- Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/
AmpereOneX

Miscellaneous:

- Sync header copies with the kernel sources

- Move some header copies used only for generating translation string
tables for ioctl cmds and other syscall integer arguments to a new
directory under tools/perf/beauty/, to separate from copies in
tools/include/ that are used to build the tools

- Introduce scrape script for several syscall 'flags'/'mask'
arguments

- Improve cpumap utilization, fixing up pairing of refcounts, using
the right iterators (perf_cpu_map__for_each_cpu), etc

- Give more details about raw event encodings in 'perf list', show
tracepoint encoding in the detailed output

- Refactor the DSOs handling code, reducing memory usage

- Document the BPF event modifier and add a 'perf test' for it

- Improve the event parser, better error messages and add further
'perf test's for it

- Add reference count checking to 'struct comm_str' and 'struct
mem_info'

- Make ARM64's 'perf test' entries for the Neoverse N1 more robust

- Tweak the ARM64's Coresight 'perf test's

- Improve ARM64's CoreSight ETM version detection and error reporting

- Fix handling of symbols when using kcore

- Fix PAI (Processor Activity Instrumentation) counter names for s390
virtual machines in 'perf report'

- Fix -g/--call-graph option failure in 'perf sched timehist'

- Add LIBTRACEEVENT_DIR build option to allow building with
libtraceevent installed in non-standard directories, such as when
doing cross builds

- Various 'perf test' and 'perf bench' fixes

- Improve 'perf probe' error message for long C++ probe names"

tools lib subcmd: Show parent options in help

I've just realized that help message in a subcommand didn't show one
in the parent command. Since the option parser understands the parent,
display code should do the same. For example, `perf ftrace latency -h`
should show options in the `perf ftrace` command too.

Before:

$ perf ftrace latency -h

Usage: perf ftrace [<options>] [<command>]
or: perf ftrace [<options>] -- [<command>] [<options>]
or: perf ftrace {trace|latency} [<options>] [<command>]
or: perf ftrace {trace|latency} [<options>] -- [<command>] [<options>]

-b, --use-bpf Use BPF to measure function latency
-n, --use-nsec Use nano-second histogram
-T, --trace-funcs <func>
Show latency of given function

After:

$ perf ftrace latency -h

Usage: perf ftrace [<options>] [<command>]
or: perf ftrace [<options>] -- [<command>] [<options>]
or: perf ftrace {trace|latency} [<options>] [<command>]
or: perf ftrace {trace|latency} [<options>] -- [<command>] [<options>]

-a, --all-cpus System-wide collection from all CPUs
-b, --use-bpf Use BPF to measure function latency
-C, --cpu <cpu> List of cpus to monitor
-n, --use-nsec Use nano-second histogram
-p, --pid <pid> Trace on existing process id
-T, --trace-funcs <func>
Show latency of given function
-v, --verbose Be more verbose
--tid <tid> Trace on existing thread id (exclusive to --pid)
