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

- 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`

Per recommendation

perf test workload: Add code_with_type test workload

The purpose of the workload is to gather samples of rust runtime. To
achieve that it has a dummy rust library linked with it.

Per recommendations for such scenarios [1], the rust library is
statically linked.

An example:

$ perf record perf test -w code_with_type
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.160 MB perf.data (4074 samples) ]

$ perf report --stdio --dso perf -s srcfile,srcline
45.16% ub_checks.rs ub_checks.rs:72
6.72% code_with_type.rs code_with_type.rs:15
6.64% range.rs range.rs:767
4.26% code_with_type.rs code_with_type.rs:21
4.23% range.rs range.rs:0
3.99% code_with_type.rs code_with_type.rs:16

Pull perf tools updates from Arnaldo Carvalho de Melo:

- Extended 'perf annotate' with DWARF type information
(--code-with-type) integration in the TUI, including a 'T'
hotkey to toggle it

- Enhanced 'perf bench mem' with new mmap() workloads and control
over page/chunk sizes

- Fix 'perf stat' error handling to correctly display unsupported
events

- Improved support for Clang cross-compilation

- Refactored LLVM and Capstone disasm for modularity

- Introduced the :X modifier to exclude an event from automatic
regrouping

- Adjusted KVM sampling defaults to use the "cycles" event to prevent
failures

- Added comprehensive support for decoding PowerPC Dispatch Trace Log
(DTL)

- Updated Arm SPE tracing logic for better analysis of memory and snoop
details

- Synchronized Intel PMU events and metrics with TMA 5.1 across
multiple processor generations

- Converted dependencies like libperl and libtracefs to be opt-in

- Handle more Rust symbols in kallsyms ('N', debugging)

- Improve the python binding to allow for python based tools to use
more of the libraries, add a 'ilist' utility to test those new
bindings

- Various 'perf test' fixes

- Kan Liang no longer a perf tools reviewer
