Implementation of ASoC topology feature for AVS driver. AudioDSP
firmware supports a wide range of audio formats, module configurations
and multi-pipeline streams. To represent all of this in form of static
ALSA topology file, which resides usually in /lib/firmware/, while
simultaneously not hindering user from any of the possibilities, 'path
template' and its 'path variants' concept is introduced. These are later
converted into actual runtime path. This part is explained in follow-up
change.
Path template is just a pattern like its name suggests. It is tied to
DAPM widget which represents a FE or a BE and is used during path
instantiation when substream is opened for streaming. It carries a range
of available variants and only these represent actual implementation of
a runtime path in AudioDSP. Only one variant of given path template can
be instantiated at a time and selection is based off of audio format
provided from userspace and currently selected one on the codec.
As firmware needs concrete data, every piece the stream is made of -
pipelines, modules - has its representing type in topology.h file. These
match firmware equivalents 1:1 in most cases. To reduce the number of
structures added - given the range of configurations supported - union
is enlisted.
AVS topology is split into two major parts: dictionaries - found within
ASoC topology manifest - and path templates - found within DAPM widget
private data. Dictionaries job is to reduce the total amount of memory
occupied by topology elements. Rather than having every pipeline and
module carry its own information, each refers to specific entry in
specific dictionary by provided (from topology file) indexes and thus
all avs_tplg_* structures and unions are mostly made of pointer fields.
tokens.h header exposes range of driver-specific tuples recognized. To
reduce code size, parsing mechanism focused around struct
avs_tplg_token_parser is added. Primitive handlers translate all
value-types known to ALSA: uuid, bool, byte, short, word and string.
Several custom parsers handle pointer-types and more complex objects.
