v2.2

The SOF Technical Stearting Committee are pleased to annouce the release of SOF v2.2.

Binaries can be downloaded here https://github.com/thesofproject/sof-bin/releases/tag/v2.2 or via git from the sof-bin repo https://github.com/thesofproject/sof-bin

High level

• Codec adapter becomes the module adapter and it's API reflects the same API used by the Windows processing modules. This will allow 3rd party processing ISVs to reuse existing code from Windows without any modifications.
• Optimisations
  • Frag API deprecated giving a ~1MCPS improvement per component.
  • Frame API precalculate block sizes for SIMD/non SIMD use cases. ~0.25MCPS improvment
• Processing modules/components
  • New up mix and down mix module added with support for HiFi4 that can up/down mix the number of channels in a stream.
• Zephyr, more native APIs added now for logging, delays, sleeping. Should be fully Zephyr Native by v2.3
• IPC4 additions that enable more advanced use cases and audio endpoints for Windows.
