[v2,00/12] Sound Open Firmware Core

Message

Liam Girdwood Aug. 31, 2018, 3:18 p.m. UTC

Sound Open Firmware (SOF) is a host and DSP architecture agnostic audio DSP firmware.
SOF is not tied to any specific host architecture or any specific
physical IO communication type (it will work with on SoC DSPs, or DSP connected
via SPI/I2C).

SOF is also not coupled to any particular DSP architecture and has abstraction
similar to Linux to allow porting to other DSP architectures. 

https://www.sofproject.org/

This patch series introduces the SOF core, later series will add host platform
support for SOF.

The SOF core manages all the core DSP services and ALSA/ASoC IO. The core is 
responsible for loading firmware, parsing topology, exposing PCMs and
kcontrols, providing debug and trace mechanisms and performing IPC between
host and DSP.

The SOF core also has logic to allow reuse of existing machine drivers for other
platforms/machines without any code modification. i.e. DAI links can be
modified at runtime to bind with SOF and SOF topologies instead of existing
hard coded DAI links and topology.

Changes since V1 :-

  o Added PM source.
  o Updated header comments to C++ style
  o Used generic private data in snd_soc_pcm_runtime
  o remove sof_get_pages()
  o Added comments for compressed SG pages.
  o Check return values for runtime_pm calls.
