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 perf: Fix compilation error with new binutils

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

Relevant binutils commit:

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

Wire up the feature test and switch to init_disassemble_info_compat(),
which were introduced in prior commits, fixing the compilation failure.

I verified that perf can still disassemble bpf programs by using bpftrace
under load, recording a perf trace, and then annotating the bpf "function"
with and without the changes. With old binutils there's no change in output
before/after this patch. When comparing the output from old binutils (2.35)
to new bintuils with the patch (upstream snapshot) there are a few output
differences, but they are unrelated to this patch. An example hunk is:

1.15 : 55:mov %rbp,%rdx
0.00 : 58:add $0xfffffffffffffff8,%rdx
0.00 : 5c:xor %ecx,%ecx
- 1.03 : 5e:callq 0xffffffffe12aca3c
+ 1.03 : 5e:call 0xffffffffe12aca3c
0.00 : 63:xor %eax,%eax
- 2.18 : 65:leaveq
- 2.82 : 66:retq
+ 2.18 : 65:leave
+ 2.82 : 66:ret

Pull irqchip updates from Marc Zyngier:

- Add new infrastructure to stop gpiolib from rewriting irq_chip
structures behind our back. Convert a few of them, but this will
obviously be a long effort.

- A bunch of GICv3 improvements, such as using MMIO-based invalidations
when possible, and reducing the amount of polling we perform when
reconfiguring interrupts.

- Another set of GICv3 improvements for the Pseudo-NMI functionality,
with a nice cleanup making it easy to reason about the various
states we can be in when an NMI fires.

- The usual bunch of misc fixes and minor improvements.

SPI NOR core changes:
- Read back written SR value to make sure the write was done correctly.
- Introduce a common function for Read ID that manufacturer drivers can

- Add helpers for read/write any register commands so manufacturer
drivers don't open code it every time.
- Clarify rdsr dummy cycles documentation.
- Add debugfs entry to expose internal flash parameters and state.

SPI NOR manufacturer drivers changes:
- Add support for Winbond W25Q512NW-IM, and Eon EN25QH256A.
- Move spi_nor_write_ear() to Winbond module since only Winbond flashes
use it.
- Rework Micron and Cypress Octal DTR enable methods to improve
readability.
- Use the common Read ID function to verify switch to Octal DTR mode for
Micron and Cypress flashes.
- Skip polling status on volatile register writes for Micron and Cypress
flashes since the operation is instant.
