perf stat:
- Add support for hybrid PMUs to support systems such as Intel Alderlake
and its BIG/little core/atom cpus.
- Introduce 'bperf' to share hardware PMCs with BPF.
- New --iostat option to collect and present IO stats on Intel hardware.
This functionality is based on recently introduced sysfs attributes
for Intel® Xeon® Scalable processor family (code name Skylake-SP):
commit bb42b3d397 ("perf/x86/intel/uncore: Expose an Uncore unit to IIO PMON mapping")
It is intended to provide four I/O performance metrics in MB per each
PCIe root port:
- Inbound Read: I/O devices below root port read from the host memory
- Inbound Write: I/O devices below root port write to the host memory
- Outbound Read: CPU reads from I/O devices below root port
- Outbound Write: CPU writes to I/O devices below root port
- Align CSV output for summary.
- Clarify --null use cases: Assess raw overhead of 'perf stat' or
measure just wall clock time.
- Improve readability of shadow stats.
perf record:
- Change the COMM when starting tha workload so that --exclude-perf
doesn't seem to be not honoured.
- Improve 'Workload failed' message printing events + what was exec'ed.
- Fix cross-arch support for TIME_CONV.
perf report:
- Add option to disable raw event ordering.
- Dump the contents of PERF_RECORD_TIME_CONV in 'perf report -D'.
- Improvements to --stat output, that shows information about PERF_RECORD_ events.
- Preserve identifier id in OCaml demangler.
perf annotate:
- Show full source location with 'l' hotkey in the 'perf annotate' TUI.
- Add line number like in TUI and source location at EOL to the 'perf annotate' --stdio mode.
- Add --demangle and --demangle-kernel to 'perf annotate'.
- Allow configuring annotate.demangle{,_kernel} in 'perf config'.
- Fix sample events lost in stdio mode.
perf data:
- Allow converting a perf.data file to JSON.
libperf:
- Add support for user space counter access.
- Update topdown documentation to permit rdpmc calls.
perf test:
- Add 'perf test' for 'perf stat' CSV output.
- Add 'perf test' entries to test the hybrid PMU support.
- Cleanup 'perf test daemon' if its 'perf test' is interrupted.
- Handle metric reuse in pmu-events parsing 'perf test' entry.
- Add test for PE executable support.
- Add timeout for wait for daemon start in its 'perf test' entries.
Build:
- Enable libtraceevent dynamic linking.
- Improve feature detection output.
- Fix caching of feature checks caching.
- First round of updates for tools copies of kernel headers.
- Enable warnings when compiling BPF programs.
Vendor specific events:
Intel:
- Add missing skylake & icelake model numbers.
arm64:
- Add Hisi hip08 L1, L2 and L3 metrics.
- Add Fujitsu A64FX PMU events.
PowerPC:
- Initial JSON/events list for power10 platform.
- Remove unsupported power9 metrics.
AMD:
- Add Zen3 events.
- Fix broken L2 Cache Hits from L2 HWPF metric.
- Use lowercases for all the eventcodes and umasks.
Hardware tracing:
arm64:
- Update CoreSight ETM metadata format.
- Fix bitmap for CS-ETM option.
- Support PID tracing in config.
- Detect pid in VMID for kernel running at EL2.
Arch specific:
MIPS:
- Support MIPS unwinding and dwarf-regs.
- Generate mips syscalls_n64.c syscall table.
PowerPC:
- Add support for PERF_SAMPLE_WEIGH_STRUCT on PowerPC.
- Support pipeline stage cycles for powerpc.
libbeauty:
- Fix fsconfig generator.
