Merge tag 'perf-tools-for-v7.0-1-2026-02-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools updates from Arnaldo Carvalho de Melo:

- Introduce 'perf sched stats' tool with record/report/diff workflows
using schedstat counters

- Add a faster libdw based addr2line implementation and allow selecting
it or its alternatives via 'perf config addr2line.style='

- Data-type profiling fixes and improvements including the ability to
select fields using 'perf report''s -F/-fields, e.g.:

'perf report --fields overhead,type'

- Add 'perf test' regression tests for Data-type profiling with C and
Rust workloads

- Fix srcline printing with inlines in callchains, make sure this has
coverage in 'perf test'

- Fix printing of leaf IP in LBR callchains

- Fix display of metrics without sufficient permission in 'perf stat'

- Print all machines in 'perf kvm report -vvv', not just the host

- Switch from SHA-1 to BLAKE2s for build ID generation, remove SHA-1
code

- Fix 'perf report's histogram entry collapsing with '-F' option

- Use system's cacheline size instead of a hardcoded value in 'perf
report'

- Allow filtering conversion by time range in 'perf data'

- Cover conversion to CTF using 'perf data' in 'perf test'

- Address newer glibc const-correctness (-Werror=discarded-qualifiers)
issues

- Fixes and improvements for ARM's CoreSight support, simplify ARM SPE
event config in 'perf mem', update docs for 'perf c2c' including the
ARM events it can be used with

- Build support for generating metrics from arch specific python
script, add extra AMD, Intel, ARM64 metrics using it

- Add AMD Zen 6 events and metrics

- Add JSON file with OpenHW Risc-V CVA6 hardware counters

- Add 'perf kvm' stats live testing

- Add more 'perf stat' tests to 'perf test'

- Fix segfault in `perf lock contention -b/--use-bpf`

- Fix various 'perf test' cases for s390

- Build system cleanups, bump minimum shellcheck version to 0.7.2

- Support building the capstone based annotation routines as a plugin

- Allow passing extra Clang flags via EXTRA_BPF_FLAGS

If babeltrace is detected check that --to-ctf functions with a data
file and in pipe mode.
