[PATCH 0/4] ASoC: SOF: ipc4/Intel: Implement split fw library loading

Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx> · Fri, 15 Sep 2023 14:40:14 +0300

Hi,

This series implements support for split library loading to comply with the HDA
DMA programming sequence recommendation, which is:
1. DSP side DMA programming and GEN bit set to 1
2. host side DMA programming and RUN bit set to 1

The SOF support for library loading is based on this sequence, backwards
compatibility with older reference firmware is supported (where only the
LOAD_LIBRARY message is supported).

Regards,
Peter
