- Skip invalid hybrid PMU on hybrid systems when the atom (little) CPUs
are offlined.

- Fix 'perf test' problems related to the recently added hybrid
(BIG/little) code.

- Split ARM's coresight (hw tracing) decode by aux records to avoid
fatal decoding errors.

- Fix add event failure in 'perf probe' when running 32-bit perf in a
64-bit kernel.

- Fix 'perf sched record' failure when CONFIG_SCHEDSTATS is not set.

- Fix memory and refcount leaks detected by ASAn when running 'perf
test', should be clean of warnings now.

- Remove broken definition of __LITTLE_ENDIAN from tools'
linux/kconfig.h, which was breaking the build in some systems.

- Cast PTHREAD_STACK_MIN to int as it may turn into 'long
sysconf(__SC_THREAD_STACK_MIN_VALUE), breaking the build in some
systems.

- Fix libperf build error with LIBPFM4=1.

- Sync UAPI files changed by the memfd_secret new syscall.

Merge tag 'perf-tools-for-v5.14-2021-07-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull more perf tool updates from Arnaldo Carvalho de Melo:
"New features:

- Enable use of BPF counters with 'perf stat --for-each-cgroup',
using per-CPU 'cgroup-switch' events with an attached BPF program
that does aggregation per-cgroup in the kernel instead of using
per-cgroup perf events.

- Add Topdown metrics L2 events as default events in 'perf stat' for
systems having those events.

Hardware tracing:

- Add a config for max loops without consuming a packet in the Intel
PT packet decoder, set via 'perf config intel-pt.max-loops=N'

Hardware enablement:

- Disable misleading NMI watchdog message in 'perf stat' on hybrid
systems such as Intel Alder Lake.

- Add a dummy event on hybrid systems to collect metadata records.

- Add 24x7 nest metric events for the Power10 platform.

Fixes:

- Fix event parsing for PMUs starting with the same prefix.

- Fix the 'perf trace' 'trace' alias installation dir.

- Fix buffer size to report iregs in perf script python scripts,
supporting the extended registers in PowerPC.

- Fix overflow in elf_sec__is_text().

- Fix 's' on source line when disasm is empty in the annotation TUI,
accessible via 'perf annotate', 'perf report' and 'perf top'.

- Plug leaks in scandir() returned dirent entries in 'perf test' when
sorting the shell tests.

- Fix --task and --stat with pipe input in 'perf report'.

- Fix 'perf probe' use of debuginfo files by build id.

- If a DSO has both dynsym and symtab ELF sections, read from both
when loading the symbol table, fixing a problem processing Fedora
32 glibc DSOs.

Libraries:

- Add grouping of events to libperf, from code in tools/perf,
allowing libperf users to use that mode.

Misc:

- Filter plt stubs from the 'perf probe --functions' output.

- Update UAPI header copies for asound, DRM, mman-common.h and the
ones affected by the quotactl_fd syscall"

libperf: Move 'leader' from tools/perf to perf_evsel::leader

Move evsel::leader to perf_evsel::leader, so we can move the group
interface to libperf.

Also add several evsel helpers to ease up the transition:

struct evsel *evsel__leader(struct evsel *evsel);
- get leader evsel

bool evsel__has_leader(struct evsel *evsel, struct evsel *leader);
- true if evsel has leader as leader

bool evsel__is_leader(struct evsel *evsel);
- true if evsel is itw own leader

void evsel__set_leader(struct evsel *evsel, struct evsel *leader);
- set leader for evsel

Committer notes:

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"
