    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
