ALSA/ASoC/SOF/SoundWire: fix Kconfig issues

In January, Intel kbuild bot and Arnd Bergmann reported multiple
issues with randconfig. This patchset builds on Arnd's suggestions to

a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
and sof-pci-dev become helpers. This will result in minor changes
required for developers/testers, i.e. modprobe snd-sof-pci will no
longer result in a probe. The SOF CI was already updated to deal with
this module dependency change and introduction of new modules.

b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
required to detect SoundWire presence in ACPI tables to sound/hda.

Merge tag 'perf-tools-for-v5.12-2020-02-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tool updates from Arnaldo Carvalho de Melo:
"New features:

- Support instruction latency in 'perf report', with both memory
latency (weight) and instruction latency information, users can
locate expensive load instructions and understand time spent in
different stages.

- Extend 'perf c2c' to display the number of loads which were blocked
by data or address conflict.

- Add 'perf stat' support for L2 topdown events in systems such as
Intel's Sapphire rapids server.

- Add support for PERF_SAMPLE_CODE_PAGE_SIZE in various tools, as a
sort key, for instance:

perf report --stdio --sort=comm,symbol,code_page_size

- New 'perf daemon' command to run long running sessions while
providing a way to control the enablement of events without
restarting a traditional 'perf record' session.

- Enable counting events for BPF programs in 'perf stat' just like
for other targets (tid, cgroup, cpu, etc), e.g.:

# perf stat -e ref-cycles,cycles -b 254 -I 1000
1.487903822 115,200 ref-cycles
1.487903822 86,012 cycles
2.489147029 80,560 ref-cycles
2.489147029 73,784 cycles
^C

The example above counts 'cycles' and 'ref-cycles' of BPF program
of id 254. It is similar to bpftool-prog-profile command, but more
flexible.

- Support the new layout for PERF_RECORD_MMAP2 to carry the DSO
build-id using infrastructure generalised from the eBPF subsystem,
removing the need for traversing the perf.data file to collect
build-ids at the end of 'perf record' sessions and helping with
long running sessions where binaries can get replaced in updates,
leading to possible mis-resolution of symbols.

- Support filtering by hex address in 'perf script'.

- Support DSO filter in 'perf script', like in other perf tools.

- Add namespaces support to 'perf inject'

- Add support for SDT (Dtrace Style Markers) events on ARM64.

perf record:

- Fix handling of eventfd() when draining a buffer in 'perf record'.

- Improvements to the generation of metadata events for pre-existing
threads (mmaps, comm, etc), speeding up the work done at the start
of system wide or per CPU 'perf record' sessions.

Hardware tracing:

- Initial support for tracing KVM with Intel PT.

- Intel PT fixes for IPC

- Support Intel PT PSB (synchronization packets) events.

- Automatically group aux-output events to overcome --filter syntax.

- Enable PERF_SAMPLE_DATA_SRC on ARMs SPE.

- Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0.

perf annotate TUI:

- Fix handling of 'k' ("show line number") hotkey

- Fix jump parsing for C++ code.

perf probe:

- Add protection to avoid endless loop.

cgroups:

- Avoid reading cgroup mountpoint multiple times, caching it.

- Fix handling of cgroup v1/v2 in mixed hierarchy.

Symbol resolving:

- Add OCaml symbol demangling.

- Further fixes for handling PE executables when using perf with Wine
and .exe/.dll files.

- Fix 'perf unwind' DSO handling.

- Resolve symbols against debug file first, to deal with artifacts
related to LTO.

- Fix gap between kernel end and module start on powerpc.

Reporting tools:

- The DSO filter shouldn't show samples in unresolved maps.

- Improve debuginfod support in various tools.

build ids:

- Fix 16-byte build ids in 'perf buildid-cache', add a 'perf test'
entry for that case.

perf test:

- Support for PERF_SAMPLE_WEIGHT_STRUCT.

- Add test case for PERF_SAMPLE_CODE_PAGE_SIZE.

- Shell based tests for 'perf daemon's commands ('start', 'stop,
'reconfig', 'list', etc).

- ARM cs-etm 'perf test' fixes.

- Add parse-metric memory bandwidth testcase.

Compiler related:

- Fix 'perf probe' kretprobe issue caused by gcc 11 bug when used
with -fpatchable-function-entry.

- Fix ARM64 build with gcc 11's -Wformat-overflow.

- Fix unaligned access in sample parsing test.

- Fix printf conversion specifier for IP addresses on arm64, s390 and
powerpc.

Arch specific:

- Support exposing Performance Monitor Counter SPRs as part of
extended regs on powerpc.

- Add JSON 'perf stat' metrics for ARM64's imx8mp, imx8mq and imx8mn
DDR, fix imx8mm ones.

- Fix common and uarch events for ARM64's A76 and Ampere eMag"

Pull perf tooling updates from Arnaldo Carvalho de Melo:
"These are additional changes to the perf tools, on top of what Ingo
already submitted.

- Further Intel PT call-trace fixes

- Improve SELinux docs and tool warnings

- Fix race at exit in 'perf record' using eventfd.

- Add missing build tests to the default set of 'make -C tools/perf
build-test'

- Sync msr-index.h getting new AMD MSRs to decode and filter in 'perf
trace'.

- Fix fallback to libaudit in 'perf trace' for arches not using
per-arch *.tbl files.

- Fixes for 'perf ftrace'.

- Fixes and improvements for the 'perf stat' metrics.

- Use dummy event to get PERF_RECORD_{FORK,MMAP,etc} while
synthesizing those metadata events for pre-existing threads.

- Fix leaks detected using clang tooling.

- Improvements to PMU event metric testing.

- Report summary for 'perf stat' interval mode at the end, summing up
all the intervals.

- Improve pipe mode, i.e. this now works as expected, continuously
dumping samples:

# perf record -g -e raw_syscalls:sys_enter | perf --no-pager script

- Fixes for event grouping, detecting incompatible groups such as:

# perf stat -e '{cycles,power/energy-cores/}' -v
WARNING: group events cpu maps do not match, disabling group:
anon group { power/energy-cores/, cycles }
power/energy-cores/: 0
cycles: 0-7

- Fixes for 'perf probe': blacklist address checking, number of
kretprobe instances, etc.

- JIT processing improvements and fixes plus the addition of a 'perf
test' entry for the java demangler.

- Add support for synthesizing first/last level cache, TLB and remove
access events from HW tracing in the auxtrace code, first to use is
ARM SPE.

- Vendor events updates and fixes, including for POWER9 and Intel.

- Allow using ~/.perfconfig for removing the ',' separators in 'perf
stat' output.

- Opt-in support for libpfm4"

"Kernel side changes:

- Add AMD Fam17h RAPL support

- Introduce CAP_PERFMON to kernel and user space

- Add Zhaoxin CPU support

- Misc fixes and cleanups

Tooling changes:

- perf record:

Introduce '--switch-output-event' to use arbitrary events to be
setup and read from a side band thread and, when they take place a
signal be sent to the main 'perf record' thread, reusing the core
for '--switch-output' to take perf.data snapshots from the ring
buffer used for '--overwrite', e.g.:

# perf record --overwrite -e sched:* \
--switch-output-event syscalls:*connect* \
workload

will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
connect syscalls.

Add '--num-synthesize-threads' option to control degree of
parallelism of the synthesize_mmap() code which is scanning
/proc/PID/task/PID/maps and can be time consuming. This mimics
pre-existing behaviour in 'perf top'.

- perf bench:

Add a multi-threaded synthesize benchmark and kallsyms parsing
benchmark.

- Intel PT support:

Stitch LBR records from multiple samples to get deeper backtraces,
there are caveats, see the csets for details.

Allow using Intel PT to synthesize callchains for regular events.

Add support for synthesizing branch stacks for regular events
(cycles, instructions, etc) from Intel PT data.

Misc changes:

- Updated perf vendor events for power9 and Coresight.

- Add flamegraph.py script via 'perf flamegraph'

- Misc other changes, fixes and cleanups - see the Git log for details

Also, since over the last couple of years perf tooling has matured and
decoupled from the kernel perf changes to a large degree, going
forward Arnaldo is going to send perf tooling changes via direct pull
requests"
