Merge tag 'perf-tools-for-v6.1-1-2022-10-07' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tools updates from Arnaldo Carvalho de Melo:

- Add support for AMD on 'perf mem' and 'perf c2c', the kernel
enablement patches went via tip.

Example:

$ sudo perf mem record -- -c 10000
^C[ perf record: Woken up 227 times to write data ]
[ perf record: Captured and wrote 58.760 MB perf.data (836978 samples) ]

$ sudo perf mem report -F mem,sample,snoop
Samples: 836K of event 'ibs_op//', Event count (approx.): 8418762
Memory access Samples Snoop
N/A 700620 N/A
L1 hit 126675 N/A
L2 hit 424 N/A
L3 hit 664 HitM
L3 hit 10 N/A
Local RAM hit 2 N/A
Remote RAM (1 hop) hit 8558 N/A
Remote Cache (1 hop) hit 3 N/A
Remote Cache (1 hop) hit 2 HitM
Remote Cache (2 hops) hit 10 HitM
Remote Cache (2 hops) hit 6 N/A
Uncached hit 4 N/A
$

- "perf lock" improvements:

- Add -E/--entries option to limit the number of entries to
display, say to ask for just the top 5 contended locks.

- Add -q/--quiet option to suppress header and debug messages.

- Add a 'perf test' kernel lock contention entry to test 'perf
lock'.

- "perf lock contention" improvements:

- Ask BPF's bpf_get_stackid() to skip some callchain entries.

The ones closer to the tooling are bpf related and not that
interesting, the ones calling the locking function are the ones
we're interested in, example of a full, unskipped callstack:

- Allow changing the callstack depth and number of entries to skip.

1 10.74 us 10.74 us 10.74 us spinlock __bpf_trace_contention_begin+0xb
0xffffffffc03b5c47 bpf_prog_bf07ae9e2cbd02c5_contention_begin+0x117
0xffffffffc03b5c47 bpf_prog_bf07ae9e2cbd02c5_contention_begin+0x117
0xffffffffbb8b8e75 bpf_trace_run2+0x35
0xffffffffbb7eab9b __bpf_trace_contention_begin+0xb
0xffffffffbb7ebe75 queued_spin_lock_slowpath+0x1f5
0xffffffffbc1c26ff _raw_spin_lock+0x1f
0xffffffffbb841015 tick_do_update_jiffies64+0x25
0xffffffffbb8409ee tick_irq_enter+0x9e

- Show full callstack in verbose mode (-v option), sometimes this
is desirable instead of showing just one callstack entry.

- Allow multiple time ranges in 'perf record --delay' to help in
reducing the amount of data collected from hardware tracing (Intel
PT, etc) when there is a rough idea of periods of time where events
of interest take time.

- Add Intel PT to record only decoder debug messages when error
happens.

- Improve layout of Intel PT man page.

- Add new branch types: alignment, data and inst faults and arch
specific ones, such as fiq, debug_halt, debug_exit, debug_inst and
debug_data on arm64.

Kernel enablement went thru the tip tree.

- Fix 'perf probe' error log check in 'perf test' when no debuginfo is
available.

- Fix 'perf stat' aggregation mode logic, it should be looking at the
CPU not at the core number.

- Fix flags parsing in 'perf trace' filters.

- Introduce compact encoding of CPU range encoding on perf.data, to
avoid having a bitmap with all the CPUs.

- Improvements to the 'perf stat' metrics, including adding
"core_wide", and computing "smt" from the CPU topology.

- Add support to the new PERF_FORMAT_LOST perf_event_attr.read_format,
that allows tooling to ask for the precise number of lost samples for
a given event.

- Add 'addr' sort key to see just the address of sampled instructions:

$ perf record -o- true | perf report -i- -s addr
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.000 MB - ]
# Samples: 12 of event 'cycles:u'
# Event count (approx.): 252512
#
# Overhead Address
# ........ ..................
42.96% 0x7f96f08443d7
29.55% 0x7f96f0859b50
14.76% 0x7f96f0852e02
8.30% 0x7f96f0855028
4.43% 0xffffffff8de01087

perf annotate: Toggle full address <-> offset display

- Add 'f' hotkey to the 'perf annotate' TUI interface when in
'disassembler output' mode ('o' hotkey) to toggle showing full
virtual address or just the offset.

- Cache DSO build-ids when synthesizing PERF_RECORD_MMAP records for
pre-existing threads, at the start of a 'perf record' session,
speeding up that record startup phase.

- Add a command line option to specify build ids in 'perf inject'.

- Update JSON event files for the Intel alderlake, broadwell,
broadwellde, broadwellx, cascadelakex, haswell, haswellx, icelake,
icelakex, ivybridge, ivytown, jaketown, sandybridge, sapphirerapids,
skylake, skylakex, and tigerlake processors.

- Update vendor JSON event files for the ARM Neoverse V1 and E1
platforms.

- Add a 'perf test' entry for 'perf mem' where a struct has false
sharing and this gets detected in the 'perf mem' output, tested with
Intel, AMD and ARM64 systems.

- Add a 'perf test' entry to test the resolution of java symbols, where
an output like this is expected:

8.18% jshell jitted-50116-29.so [.] Interpreter
0.75% Thread-1 jitted-83602-1670.so [.] jdk.internal.jimage.BasicImageReader.getString(int)

- Add tests for the ARM64 CoreSight hardware tracing feature, with
specially crafted pureloop, memcpy, thread loop and unroll tread that
then gets traced and the output compared with expected output.

Documentation explaining it is also included.

- Add per thread Intel PT 'perf test' entry to check that
PERF_RECORD_TEXT_POKE events are recorded per CPU, resulting in a
mixture of per thread and per CPU events and mmaps, verify that this
gets all recorded correctly.

- Introduce pthread mutex wrappers to allow for building with clang's
-Wthread-safety, i.e. using the "guarded_by" "pt_guarded_by"
"lockable", "exclusive_lock_function", "exclusive_trylock_function",
"exclusive_locks_required", and "no_thread_safety_analysis" compiler
function attributes.

- Fix empty version number when building outside of a git repo.

- Improve feature detection display when multiple versions of a feature
are present, such as for binutils libbfd, that has a mix of possible
ways to detect according to the Linux distribution.

Previously in some cases we had:

Auto-detecting system features
<SNIP>
... libbfd: [ on ]
... libbfd-liberty: [ on ]
... libbfd-liberty-z: [ on ]
<SNIP>

Now for this case we show just the main feature:

Auto-detecting system features
<SNIP>
... libbfd: [ on ]
<SNIP>

- Remove some unused structs, variables, macros, function prototypes
and includes from various places.

perf tools: Remove special handling of system-wide evsel

For system-wide evsels, the thread map should be dummy - i.e. it has a
single entry of -1. But the code guarantees such a thread map, so no
need to handle it specially.

No functional change intended.

perf tools: Add debug messages and comments for testing

Add debug messages to enable scripts to track aspects of 'perf record'
behaviour. The messages will be consumed after 'perf record' has run,
with the exception of "perf record has started" which is consequently
flushed.

Put comments so developers know which messages are also being used by test
scripts.

MediaTek Helio X10 MT6795 - MT6331/6332 Regulators

Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>:

In an effort to give some love to the apparently forgotten MT6795 SoC,
I am upstreaming more components that are necessary to support platforms
powered by this one apart from a simple boot to serial console.

This series adds support for the regulators found in MT6331 and MT6332
main/companion PMICs.

Adding support to each driver in each subsystem is done in different
patch series as to avoid spamming uninteresting patches to maintainers.

Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.
