ASoC: Fixes for v6.9
A relatively large set of fixes here, the biggest piece of it is a series correcting some problems with the delay reporting for Intel SOF cards but there's a bunch of other things. Everything here is driver specific except for a fix in the core for an issue with sign extension handling volume controls.

Pull perf tools updates from Namhyung Kim: "perf stat:
- Support new 'cluster' aggregation mode for shared resources depending on the hardware configuration:
$ sudo perf stat -a --per-cluster -e cycles,instructions sleep 1
Performance counter stats for 'system wide':

1.002407989 seconds time elapsed
- Various fixes and cleanups for event metrics including NaN handling
perf script:
- Use libcapstone if available to disassemble the instructions. This enables 'perf script -F disasm' and 'perf script --insn-trace=disasm' (for Intel-PT):
$ perf script -F event,ip,disasm cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffa9839d25 movq %rax, %r14 cycles:P: ffffffffa9cdcaf0 endbr64 cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffaa401f86 iretq cycles:P: ffffffffa99c4de5 movq 0x30(%rcx), %r8 cycles:P: ffffffffa988d428 wrmsr cycles:P: ffffffffaa401f86 iretq cycles:P: ffffffffa9907983 movl 0x68(%rbx), %eax cycles:P: ffffffffa988d428 wrmsr
- Expose sample ID / stream ID to python scripts
perf test:
- Add more perf test cases from Redhat internal test suites. This time it adds the base infra and a few perf probe tests. More to come. :)
- Add 'perf test -p' for parallel execution and fix some issues found by the parallel test
- Support symbol test to print symbols in given (active) module:
$ perf test -F -v Symbols --dso /lib/modules/$(uname -r)/kernel/fs/ext4/ext4.ko --- start --- Testing /lib/modules/6.5.13-1rodete2-amd64/kernel/fs/ext4/ext4.ko Overlapping symbols: 7a990-7a9a0 l __pfx_ext4_exit_fs 7a990-7a9a0 g __pfx_cleanup_module Overlapping symbols: 7a9a0-7aa1c l ext4_exit_fs 7a9a0-7aa1c g cleanup_module ...
JSON metric updates:
- A new round of Intel metric updates
- Support Power11 PVR (compatible to Power10)
- Fix cache latency events on Zen 4 to set SliceId properly
Internal:
- Fix reference counting for 'map' data structure, tireless work from Ian!
- More memory optimization for struct thread and annotate histogram. Now, 'perf report' (TUI) and 'perf annotate' should be much lighter-weight in terms of memory footprint
- Support cross-arch perf register access. Clean up the build configuration so that it can detect arch-register support at runtime. This can allow to parse register data in sample which was recorded in a different arch
Others:
- Sync task state in 'perf sched' to kernel using trace event fields. The task states have been changed so tools cannot assume a fixed encoding
- Clean up 'perf mem' to generalize the arch-specific events
- Add support for local and global variables to data type profiling. This would increase the success rate of type resolution with DWARF
- Add short option -H for --hierarchy in 'perf report' and 'perf top'"

tools: perf: Expose sample ID / stream ID to python scripts
perf script exposes the evsel_name to python scripts as part of the data passed to the sample or tracepoint handler function, and it passes the id and stream_id to the throttled/unthrottled handler functions. This makes matching throttle events and samples difficult.
To make this possible, this change exposes the sample id and stream_id values to the script.

Merge tag 'perf-tools-for-v6.3-1-2023-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux
Pull perf tools updates from Arnaldo Carvalho de Melo: "Miscellaneous:
- Add Ian Rogers to MAINTAINERS as a perf tools reviewer.
- Add support for retire latency feature (pipeline stall of a instruction compared to the previous one, in cycles) present on some Intel processors.
- Add 'perf c2c' report option to show false sharing with adjacent cachelines, to be used in machines with cacheline prefetching, where accesses to a cacheline brings the next one too.
- Skip 'perf test bpf' when the required kernel-debuginfo package isn't installed.
- Avoid d3-flame-graph package dependency in 'perf script flamegraph', making this feature more generally available.
- Add JSON metric events to present CPI stall cycles in Power10.
- Assorted improvements/refactorings on the JSON metrics parsing code.
perf lock contention:
- Add -o/--lock-owner option:
$ sudo ./perf lock contention -abo -- ./perf bench sched pipe # Running 'sched/pipe' benchmark: # Executed 1000000 pipe operations between two processes
Total time: 4.766 [sec]
4.766540 usecs/op 209795 ops/sec contended total wait max wait avg wait pid owner

The owner is unknown in most cases. Filtering only for the mutex locks, it will more likely get the owners.
- -S/--callstack-filter is to limit display entries having the given string in the callstack:
$ sudo ./perf lock contention -abv -S net sleep 1 ... contended total wait max wait avg wait type caller

Please note that to have the -b option (BPF) working above one has to build with BUILD_BPF_SKEL=1.
- Add more 'perf test' entries to test these new features.
perf script:
- Add 'cgroup' field for 'perf script' output:
$ perf record --all-cgroups -- true $ perf script -F comm,pid,cgroup true 337112 /user.slice/user-657345.slice/user@657345.service/... true 337112 /user.slice/user-657345.slice/user@657345.service/... true 337112 /user.slice/user-657345.slice/user@657345.service/... true 337112 /user.slice/user-657345.slice/user@657345.service/...
- Add support for showing branch speculation information in 'perf script' and in the 'perf report' raw dump (-D).
perf record:
- Fix 'perf record' segfault with --overwrite and --max-size.
perf test/bench:
- Switch basic BPF filtering test to use syscall tracepoint to avoid the variable number of probes inserted when using the previous probe point (do_epoll_wait) that happens on different CPU architectures.
- Fix DWARF unwind test by adding non-inline to expected function in a backtrace.
- Use 'grep -c' where the longer form 'grep | wc -l' was being used.
- Add getpid and execve benchmarks to 'perf bench syscall'.
Intel PT:
- Add support for synthesizing "cycle" events from Intel PT traces as we support "instruction" events when Intel PT CYC packets are available. This enables much more accurate profiles than when using the regular 'perf record -e cycles' (the default) when the workload lasts for very short periods (<10ms).
- .plt symbol handling improvements, better handling IBT (in the past MPX) done in the context of decoding Intel PT processor traces, IFUNC symbols on x86_64, static executables, understanding .plt.got symbols on x86_64.
- Add a 'perf test' to test symbol resolution, part of the .plt improvements series, this tests things like symbol size in contexts where only the symbol start is available (kallsyms), etc.
- Better handle auxtrace/Intel PT data when using pipe mode (perf record sleep 1|perf report).
- Fix symbol lookup with kcore with multiple segments match stext, getting the symbol resolution to just show DSOs as unknown.
ARM:
- Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace Macrocell v4).
- Ensure ARM64 CoreSight timestamps don't go backwards.
- Document that ARM64 SPE (Statistical Profiling Extension) is used with 'perf c2c/mem'.
- Add raw decoding for ARM64 SPEv1.2 previous branch address.
- Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1, TLB, cache, branch, PE utilization and instruction mix metrics.
- Update decoder code for OpenCSD version 1.4, on ARM64 systems.
- Fix command line auto-complete of CPU events on aarch64.
Build:
- Fix 'perf probe' and 'perf test' when libtraceevent isn't linked, as several tests use tracepoints, those should be skipped.
- More fallout fixes for the removal of tools/lib/traceevent/.
- Fix build error when linking with libpfm"
