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 data: Add JSON export

This adds a feature to export perf data to JSON.

The resolved symbols are exported into the JSON so that external tools
don't need to load the dsos themselves (or even have access to them at
all.) This makes it easy to load and analyze perf data with standalone
tools where direct perf or libbabeltrace integration is impractical.

The exporter uses a minimal inline JSON encoding without any external
dependencies. Currently it only outputs some headers and sample metadata
but it's easily extensible.

Use it like this:

$ perf data convert --to-json out.json

Committer notes:

Fixup a __printf() bug that broke the build:

util/data-convert-json.c:103:11: error: expected ‘)’ before numeric constant
103 | __(printf, 5, 6)
| ^~
| )
util/data-convert-json.c: In function ‘output_sample_callchain_entry’:
util/data-convert-json.c:124:2: error: implicit declaration of function ‘output_json_key_format’; did you mean ‘output_json_format’? [-Werror=implicit-function-declaration]
124 | output_json_key_format(out, false, 5, "ip", "\"0x%" PRIx64 "\"", ip);
| ^~~~~~~~~~~~~~~~~~~~~~
| output_json_format

Also had to add this patch to fix errors reported by various versions of
clang:

- if (al && al->sym && al->sym->name && strlen(al->sym->name) > 0) {
+ if (al && al->sym && al->sym->namelen) {

al->sym->name is a zero sized array, to avoid one extra alloc in the
symbol__new() constructor, sym->namelen carries its strlen.

Committer testing:
