Merge tag 'perf-tools-for-v6.0-2022-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:

- Introduce 'perf lock contention' subtool, using new lock contention
tracepoints and using BPF for in kernel aggregation and then
userspace processing using the perf tooling infrastructure for
resolving symbols, target specification, etc.

Since the new lock contention tracepoints don't provide lock names,
get up to 8 stack traces and display the first non-lock function
symbol name as a caller:

$ perf lock report -F acquired,contended,avg_wait,wait_total

Name acquired contended avg wait total wait

update_blocked_a... 40 40 3.61 us 144.45 us
kernfs_fop_open+... 5 5 3.64 us 18.18 us
_nohz_idle_balance 3 3 2.65 us 7.95 us
tick_do_update_j... 1 1 6.04 us 6.04 us
ep_scan_ready_list 1 1 3.93 us 3.93 us

Supports the usual 'perf record' + 'perf report' workflow as well as
a BCC/bpftrace like mode where you start the tool and then press
control+C to get results:

$ sudo perf lock contention -b
^C
contended total wait max wait avg wait type caller

...

- Add new 'perf kwork' tool to trace time properties of kernel work
(such as softirq, and workqueue), uses eBPF skeletons to collect info
in kernel space, aggregating data that then gets processed by the
userspace tool, e.g.:

# perf kwork report

See commit log messages for more examples with extra options to limit
the events time window, etc.

- Add support for new AMD IBS (Instruction Based Sampling) features:

With the DataSrc extensions, the source of data can be decoded among:
- Local L3 or other L1/L2 in CCX.
- A peer cache in a near CCX.
- Data returned from DRAM.
- A peer cache in a far CCX.
- DRAM address map with "long latency" bit set.
- Data returned from MMIO/Config/PCI/APIC.
- Extension Memory (S-Link, GenZ, etc - identified by the CS target
and/or address map at DF's choice).
- Peer Agent Memory.

- Support hardware tracing with Intel PT on guest machines, combining
the traces with the ones in the host machine.

- Add a "-m" option to 'perf buildid-list' to show kernel and modules
build-ids, to display all of the information needed to do external
symbolization of kernel stack traces, such as those collected by
bpf_get_stackid().

- Add arch TSC frequency information to perf.data file headers.

- Handle changes in the binutils disassembler function signatures in
perf, bpftool and bpf_jit_disasm (Acked by the bpftool maintainer).

- Fix building the perf perl binding with the newest gcc in distros
such as fedora rawhide, where some new warnings were breaking the
build as perf uses -Werror.

- Add 'perf test' entry for branch stack sampling.

- Add ARM SPE system wide 'perf test' entry.

- Add user space counter reading tests to 'perf test'.

- Build with python3 by default, if available.

- Add python converter script for the vendor JSON event files.

- Update vendor JSON files for most Intel cores.

- Add vendor JSON File for Intel meteorlake.

- Add Arm Cortex-A78C and X1C JSON vendor event files.

- Add workaround to symbol address reading from ELF files without phdr,
falling back to the previoous equation.

- Convert legacy map definition to BTF-defined in the perf BPF script
test.

- Rework prologue generation code to stop using libbpf deprecated APIs.

- Add default hybrid events for 'perf stat' on x86.

- Add topdown metrics in the default 'perf stat' on the hybrid machines
(big/little cores).

- Prefer sampled CPU when exporting JSON in 'perf data convert'

- Fix ('perf stat CSV output linter') and ("Check branch stack
sampling") 'perf test' entries on s390.

tools build: Add feature test for init_disassemble_info API changes

binutils changed the signature of init_disassemble_info(), which now causes
compilation failures for tools/{perf,bpf}, e.g. on debian unstable.

Relevant binutils commit:

https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=60a3da00bd5407f07

This commit adds a feature test to detect the new signature. Subsequent
commits will use it to fix the build failures.
