If the systemdsystemunitdir got passed anyway as a variable, we don't
need the systemd.pc dependency anymore and allow building without a
systemd build-dependency.
Relevant in Alpine Linux, where we allowed systemd services to be
(sub-)packaged (e.g. for downstreams like postmarketOS), but don't have
systemd pacakged in Alpine itself, yet.

The UCM configuration for AMD ACP digital microphones combines HDA analog card
with ASoC AMD ACP digital microphone card. When the ACP microphone card
is detected later than HDA analog card, the UCM initialization for HDA
analog card should be executed again.
Additional changes:
Added --with-alsactl-udev-extra-test argument to handle the tests for
directories. The default value was kept.
Added --alsactl-udev-args argument to pass extra arguments to alsactl
in the udev rule.
Note: The autoconf does not handle correctly spaces so configure
call like 'configure --alsactl-udev-args="-E ENV=abcd"' is not allowed.
Substitue '__' string as ' ' for this reason.
Example:
configure --with-alsactl-udev-args="-E__ENV=abcd" \
--with-alsactl-udev-extra-test='TEST=="/abcd",__TEST=="/xyz",'

aplaymidi2 is a program similar like aplaymidi, but intended for
playing back a MIDI Clip file that was introduced for handling UMP.
MIDI Clip file contains UMP packets, and its structure is much simpler
than SMF.
The options are mostly same as aplaymidi, but I omitted -l option for
simplifying the code.

aseqsend is a command-line utility which allows one to send SysEx
(system exclusive) data to ALSA MIDI seqencer port. It can also send
any other MIDI commands.

Add the support for showing the UMP events to aseqdump.
With the new option -u, the program can start as a UMP sequencer
client and receive UMP events instead of the legacy MIDI events.
Also, the automatic event conversion among legacy and UMP clients can
be suppressed by the new -r option, too.

The microphone arrays for Intel platforms are described in the
ACPI NHLT table. This table is available in sysfs. Parse this
information and use a more common format (json) for output. This
information is usable for the further DSP processing.

- ERESTART not supported platform: use EINTR instead
- add include/os_compat.h, well-used OS specific definition
- copied include/bswap.h from alsa-lib
- EPIPE and ESTRPIPE are different usage, but currently
EPIPE is used when ESTRPIPE is not defined.
To fix this problem, assign ESPIPE instead.

Add Intel nhlt acpi table encoder plugin into topology2.0 processing.
Nhlt internal structure is defined in:
https://01.org/sites/default/files/595976_intel_sst_nhlt.pdf
Nhlt acpi table contain vendor specific binary data blobs that are used
in some Intel dsp platforms for configuring the dmic and ssp hardware.
The function of this code is mainly to generate the vendor specific
binary blobs, but as there is existing nhlt parser code and header in
kernel there's no point of re-inventing the container: just use the
existing nhlt acpi table format. Basically this code is creating similar
nhlt acpi table that you would get from: cat
/sys/firmware/acpi/tables/NHLT
This code will have implementation for dmic and ssp endpoints. Thus the
code will translate the topology dai tokens into vendor specific binary
blobs and pack them into nhlt acpi table. Ssp and dmic code is lifted
from Sound Open Firmware (sof) code base, thus it will have BSD-3
license.
This plugin can be enabled from command line with:
alsatplg -DPREPROCESS_PLUGINS="nhlt" -c foo.conf -p -o bar.tplg
You can also dump the nhlt binary into a file with additional define:
-DNHLT_BIN="nhlt.bin"

This is a preparation to use memfd_create(2) system call for test programs
of axfer. The system call was introduced at Linux kernel v3.17 and
relatively new.
For safe, this commit adds detection of memfd_create() in autotools side
so that application can handle the case not to detect.

At present, axfer is designed to use several types of backend for
transmission of data frames. This commit is an implementation
example of the backend.
Libffado is a userspace library for transmission of data frames according
to protocols similar to IEC 61883-1/6. This library handles audio and
music units on IEEE 1394 bus.
Unfortunately, this library executes ctor/dtor of instances for some
objects in startup/finish routines of C runtime. As a result, it outputs
some superfluous messages even if the backend is not actually used.
Furthermore, this library brings memory leak internally. Therefore,
it's not practical to build this backend for generic purposes. Although
the backend implementation works fine, this commit is just for technical
preview.

In former commits, container module gets supports of parser/builder for

This includes positive test cases only. The test cases actually generate

This commit adds a new command, 'axfer' ('ALSA transfer'), to transfer data
frames described in asound.h. This command is intended to replace current
aplay. The most of features and command line parameters come from aplay as
much as possible, while it has more better feature and code to maintain.
This commit adds an entry point for this command. Current option system of
aplay is still available, while this command has a sub-command system like
commands in iproute2.
Currently, two sub-commands are supported; 'list' and 'transfer'. The
'list' sub-command has the same effect as '-l' and '-L' options of aplay.
The 'transfer' sub-command has the same effect as the main feature of
aplay. For the sub-command system, an option for stream direction is
required; '-P' for playback and '-C' for capture. If you create symbolic
links to this binary for aplay/arecord, please execute:
$ ln -s axfer aplay
$ ln -s axfer arecord
Actual code for each sub-command will be implemented in later commits.
