Hi Rander,

Regarding your patch:

https://github.com/thesofproject/sof/pull/4536/commits/12ca2c956e5be49 49e61186def582def7f188528

We've seen this new IPC:

case SOF_IPC4_GLB_LOAD_MULTIPLE_MODULES:
case SOF_IPC4_GLB_UNLOAD_MULTIPLE_MODULES:
      tr_err(&ipc_tr, "not implemented ipc message type %d", type);
       ret = IPC4_UNAVAILABLE;

Is this loading a new binary module for SOF to later use? Is there any documentation about this? Or a pointer in the converged-modules repo?

[Rander] yes, it is for future IPC4. Document is not ready. I will notify you if it is ready. Liam has a schedule for this task.

We are working on implementing a similar feature and we could use and work previously done.

thanks, Daniel.
