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

perf test script: Add perl script testing support
Basic coverage of perl script support from `perf script`. This is disabled by default and so the test will most normally skip.
