Merge tag 'perf-tools-for-v5.13-2021-04-29' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tool updates from Arnaldo Carvalho de Melo:
"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)
in commit bb42b3d39781 ("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 updates:

- 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"

perf session: Dump PERF_RECORD_TIME_CONV event

Now perf tool uses the common stub function process_event_op2_stub() for
dumping TIME_CONV event, thus it doesn't output the clock parameters
contained in the event.

This patch adds the callback function for dumping the hardware clock
parameters in TIME_CONV event.
