- 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.
