Update sof-firmware to 2.0

Authored by TClark77 on Dec 26 2021, 8:02 PM.




  • Performance improvements in copy functions for most components with less memory access. Some processing code paths improved by up to 40% fewer cycles than v1.9 with the same audio quality.
  • Stability improvements on multi-core support on Intel cAVS platforms which can now support running dynamic pipelines on any DSP core.
  • Zephyr RTOS is now used instead of XTOS for community release for the APL platform. Zephyr integration has reached feature parity on several Intel platforms. This has led to a lot of code simplification and reductions in the SOF application code with more integration planned for v2.1.
  • Support for basic playback and capture now on certain TGL Windows-based devices via the IPC4 protocol.
