The SOF ALSA plugin allows SOF topologies to be run on the host. The plugin
is still WIP with many rough edges that need refined before production
deployment, however the plugin is usable today as a rapid development
framework for SOF infrastructure and processing.
Features that are function in the current implementation
* aplay & arecord usage working today
* modules are loaded as SO shared libraries.
* topology is parsed by the plugin and pipelines associated with the requested PCM ID are loaded
* pipelines run as individual userspace threads
* pipelines can be pinned to efficency cores
* pipelines can use realtime priority.
* alsa sink and alsa source modules available.
* pipelines can block (non blocking and mmap todo)
* 16-bit playback and capture support. Other formats to be added soon
