Expand the pre-processor to allow for expanding the definitions,
object attribute references and arithmetic expressions within strings.
With this extension its possible to embedded definitions or attribute
references into topology string objects. For example:
Define {
PCM_NUMBER 1
}
Object.Pipeline {
pcm-playback.0 {
Object.Widget {
copier.1 {
copier_type "host"
}
gain.1 {
Object.Control.mixer.1 {
name 'hw:$[$PCM_NUMBER - 1] Playback Volume'
}
}
Object.Base {
route.1 {
source copier.host.$index.1
sink gain.$index.1
}
}
}
In the example the $[$PCM_NUMBER - 1] would be replaced with the
result of arithmetic expression '1 - 1' in other words '0' , and
$index in all occurrences with index attribute found from pipeline
object. Any non alpha numeric or '_' character are treated as
delimiters for variable names if $[]-notation is not used.

Currently, The IncludeByKey mechanism only supports conditionally
including a topology conf file. Even if we only
want to conditionally include a small conf block, we have
to use a conf file and in the end we will have a lot of
trivial conf files that only contain a single conf blocks.
This patch extends the use of IncludeByKey ito support including conf
blocks conditionally. For example, the block below will include the route
conditionally based on the variable definition COPIER_ROUTE.
Define {
COPIER_ROUTE 1
}
IncludeByKey.COPIER_ROUTE {
"1" {
Object.Base.route.11 {
source copier.module.8.2

Ssp plugin had already a definition for newer nhlt blob version 1.5.
Add support to generate that instead of legacy blob. Never blob can be
generated by adding "version" field in SSP dai topology2 definition and
setting it to lower 16 bits of SSP_BLOB_VER_1_5 (0xee000105) -> 0x105
i.e 8 bits for major and 8 bits for minor version.
SSP."0" {

Intel ssp blob can have auxiliary controls catenated as tlv array at the
end of its "normal" data blob. These are needed in some platforms for
example to enable hardware clocks earlier than streaming starts.
In topology the auxiliary data classes are embedded into hw_config and
can be instantiated like:
Object.Base.hw_config."SSP0_0" {
id 0
mclk_freq 38400000
bclk_freq 256000
tdm_slot_width 16
format "DSP_A"
bclk "codec_provider"
fsync "codec_provider"
fsync_freq 16000
Object.Base.mn_config."MN_0" {
m_div 100
n_div 200

Also replace lseek64 with lseek.
_FILE_OFFSET_BITS=64 is passed to needed platforms since configure uses
AC_SYS_LARGEFILE macro. Therefore off_t is already 64-bit and lseek is
same as lseek64.
Additionally this fixes buils with latest musl where these lfs64
functions are moved out from _GNU_SOURCE and under _LARGEFILE64_SOURCE
macro alone. This makes the builds fail on 32-bit platforms even though
default off_t on musl is 64-bit always.

Commit 9a8fcec ("amidi: add timestamp option for dump") removed the
space between bytes when dumping MIDI, changing the output from:
90 45 40
80 45 00
to:
904540
804500
It seems that this was an unintentional side effect of refactoring the
code to add the new timestamp output but the result is less readable
than it was before.
Restore the space between bytes in the same message.

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"

Add a simple plugin interface for processing the topology tree. There
can be cases where parts of the topology need to be translated from the
original format into something else. For example one could calculate
some kind of filter coefficients from filter parameters or some other
binary interface parameters from plain text topology tokens.
Mechanism is similar as in alsa-plugins and in the plugin there should
be only 1 function exported of the form:
int _snd_topology_##pluginname##_process (snd_config_t *input, snd_config_t *output)
Input and output parameters are snd_config tree before and after topology2
pre-processing. So the plugin can modify both if needed. There are cases
where the plugin may need to get information from input tree, but make
modifications to the output.
The plugins to be used can be defined in command line with:
alsatplg -DPREPROCESS_PLUGINS="foobar" -c topology.conf -p -o topology.tplg
Multiple plugins should be separated by ":".
Plugins to be used can also be defined with "Define" clause inside the
topology file (but command line takes precedence):
Define {
PREPROCESS_PLUGINS "foobar"
}
