Merge tag 'kvmarm-fixes-6.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

KVM/arm64 fixes for 6.12, take #1

- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

ASoC: Fixes for v6.12

A bunch of fixes here that came in during the merge window and the first
week of release, plus some new quirks and device IDs. There's nothing
major here, it's a bit bigger than it might've been due to there being
no fixes sent during the merge window due to your vacation.

Merge tag 'perf-tools-for-v6.12-1-2024-09-19' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools updates from Arnaldo Carvalho de Melo:

- Use BPF + BTF to collect and pretty print syscall and tracepoint
arguments in 'perf trace', done as an GSoC activity

- Data-type profiling improvements:

- Cache debuginfo to speed up data type resolution

- Add the 'typecln' sort order, to show which cacheline in a target
is hot or cold. The following shows members in the cfs_rq's first
cache line:

$ perf report -s type,typecln,typeoff -H
...
- 2.67% struct cfs_rq
+ 1.23% struct cfs_rq: cache-line 2
+ 0.57% struct cfs_rq: cache-line 4
+ 0.46% struct cfs_rq: cache-line 6
- 0.41% struct cfs_rq: cache-line 0
0.39% struct cfs_rq +0x14 (h_nr_running)
0.02% struct cfs_rq +0x38 (tasks_timeline.rb_leftmost)

- When a typedef resolves to a unnamed struct, use the typedef name

- When a struct has just one basic type field (int, etc), resolve
the type sort order to the name of the struct, not the type of
the field

- Support type folding/unfolding in the data-type annotation TUI

- Fix bitfields offsets and sizes

- Initial support for PowerPC, using libcapstone and the usual
objdump disassembly parsing routines

- Add support for disassembling and addr2line using the LLVM libraries,
speeding up those operations

- Support --addr2line option in 'perf script' as with other tools

- Intel branch counters (LBR event logging) support, only available in
recent Intel processors, for instance, the new "brcntr" field can be
asked from 'perf script' to print the information collected from this
feature:

$ perf script -F +brstackinsn,+brcntr

# branch-instructions:ppp = A
# branch-misses = B

- Support Timed PEBS (Precise Event-Based Sampling), a recent hardware
feature in Intel processors

- Add 'perf ftrace profile' subcommand, using ftrace's function-graph
tracer so that users can see the total, average, max execution time
as well as the number of invocations easily, for instance:

$ sudo perf ftrace profile -G __x64_sys_perf_event_open -- \
perf stat -e cycles -C1 true 2> /dev/null | head
# Total (us) Avg (us) Max (us) Count Function

- 'perf sched timehist' improvements, including the addition of
priority showing/filtering command line options

- Varios improvements to the 'perf probe', including 'perf test'
regression testings

- Introduce the 'perf check', initially to check if some feature is
in place, using it in 'perf test'

- Various fixes for 32-bit systems

- Address more leak sanitizer failures

- Fix memory leaks (LBR, disasm lock ops, etc)

- More reference counting fixes (branch_info, etc)

- Constify 'struct perf_tool' parameters to improve code generation
and reduce the chances of having its internals changed, which isn't
expected

- More constifications in various other places

- Add more build tests, including for JEVENTS

- Add more 'perf test' entries ('perf record LBR', pipe/inject,
--setup-filter, 'perf ftrace', 'cgroup sampling', etc)

- Inject build ids for all entries in a call chain in 'perf inject',
not just for the main sample

- Improve the BPF based sample filter, allowing root to setup filters
in bpffs that then can be used by non-root users

- Allow filtering by cgroups with the BPF based sample filter

- Allow a more compact way for 'perf mem report' using the
-T/--type-profile and also provide a --sort option similar to the one
in 'perf report', 'perf top', to setup the sort order manually

- Fix --group behavior in 'perf annotate' when leader has no samples,
where it was not showing anything even when other events in the group
had samples

- Fix spinlock and rwlock accounting in 'perf lock contention'

- Fix libsubcmd fixdep Makefile dependencies

- Improve 'perf ftrace' error message when ftrace isn't available

- Update various Intel JSON vendor event files

perf stat: Fork and launch 'perf record' when 'perf stat' needs to get retire latency value for a metric.

When retire_latency value is used in a metric formula, evsel would fork
a 'perf record' process with "-e" and "-W" options. 'perf record' will
collect required retire_latency values in parallel while 'perf stat' is
collecting counting values.

At the point of time that 'perf stat' stops counting, evsel would stop
'perf record' by sending sigterm signal to 'perf record' process.
Sampled data will be processed to get retire latency value. Another
thread is required to synchronize between 'perf stat' and 'perf record'
when we pass data through pipe.

Retire_latency evsel is not opened for 'perf stat' so that there is no
counter wasted on it. This commit includes code suggested by Namhyung to
adjust reading size for groups that include retire_latency evsels.

In current :R parsing implementation, the parser would recognize events
with retire_latency modifier and insert them into the evlist like a
normal event. Ideally, we need to avoid counting these events.

In this commit, at the time when a retire_latency evsel is read, set the
retire latency value processed from the sampled data to count value.
This sampled retire latency value will be used for metric calculation
and final event count print out. No special metric calculation and event
print out code required for retire_latency events.

Merge tag 'perf-tools-for-v6.11-2024-07-16' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-tools

Pull perf tools updates from Namhyung Kim:
"Build:

- Build each directory as a library so that depedency check for the
python extension module can be automatic

- Use pkg-config to check libtraceevent and libtracefs

perf sched:

- Add --task-name and --fuzzy-name options for `perf sched map`

It focuses on selected tasks only by removing unrelated tasks in
the output. It matches the task comm with the given string and the
--fuzzy-name option allows the partial matching:

$ sudo perf sched record -a sleep 1

$ sudo perf sched map --task-name kworker --fuzzy-name

- Fix -r/--repeat option of perf sched replay

The documentation said -1 will work as infinity but it didn't
accept the value. Update the code and document to use 0 instead

- Fix perf sched timehist to account the delay time for preempted
tasks

Perf event filtering:

- perf top gained filtering support on regular events using BPF like
perf record. Previously it was able to use it for tracepoints only

- The BPF filter now supports filtering by UID/GID. This should be
preferred than -u <UID> option as it's racy to scan /proc to check
tasks for the user and fails to open an event for the task if it's
already gone

$ sudo perf top -e cycles --filter "uid == $(id -u)"

perf report:

- Skip dummy events in the group output by default. The --skip-empty
option controls display of empty events without samples. But perf
report can force display all events in a group

In this case, auto-added a dummy event (for a system-wide record)
ends up in the output. Now it can skip those empty events even in
the group display mode

To preserve the old behavior, run this:

$ perf report --group --no-skip-empty

perf stat:

- Choose the most disaggregate option when multiple aggregation
options are given. It used to pick the last option in the command
line but it can be confusing and not consistent. Now it'll choose
the smallest unit

For example, it'd aggregate the result per-core when the user gave
both --per-socket and --per-core options at the same time

Internals:

- Fix `perf bench` when some CPUs are offline

- Fix handling of JIT symbol mappings to accept "/tmp/perf-${PID}.map
patterns only so that it can not be confused by other /tmp/perf-*
files

- Many improvements and fixes for `perf test`

Others:

- Support some new instructions for Intel-PT

- Fix syscall ID mapping in perf trace

- Document AMD IBS PMU usages

- Change `perf lock info` to show map and thread info by default

Vendor JSON events:

- Update Intel events and metrics

- Add i.MX9[35] DDR metrics"
