Question Regarding SoundWire bus support about dmf HOT 11 CLOSED

Hi @alkovacs,

I am personally not familiar with Soundwire. Let me ask the rest of the team about your query.

You are, of course, welcome to add the support and we are happy to add that support to DMF Library after review.
The Soundwire Module would have GPIO, SPB Child Modules per the information you provided above.

Let me get back to you.

Sorry for the delay...I am still trying to get more information. I will get back to you with an answer soon.

You should not include files as you are doing...that is not correct. DMF is designed so that you only need to include:

#include <initguid.h>
#include "DmfModules.Library.h"

DmfModules.Library.h automatically includes everything you need:

1. DMF Framework
2. All the DMF Modules.
3. All the WDF and NT dependencies.

If you include as you are doing it will not not work because there are many dependencies as well as the C and C++ compatibility issues that are all solved for you. Once you have included DmfModules.Library.h you can access any Module with ease.

Can you do that? Delete all your #include statements and replace with the above two lines. If you still have an issue, let me know.

Sorry, I just realized you said, "in one Module..." The above instructions are for the Client driver.

For Modules, you should do exactly what every other Module does:

// DMF and this Module's Library specific definitions.
//
#include "DmfModule.h"
#include "DmfModules.Library.h"
#include "DmfModules.Library.Trace.h"

#if defined(DMF_INCLUDE_TMH)
#include "Dmf_....tmh"
#endif

In this case, (for Modules only) you add one extra #include before DmfModules.Library.h: #include "DmfModule.h"

This allows the Module to access APIs that are only accessible by Modules and not Client drivers.

Hi... Great to hear. I will verify documentation is clear on this point. Probably it is not. It is not the first time this issue has come up.

Hi, I have made progress in SoundWire query...but I still need to gather more information. I will update this thread when I have made more progress. I hope that will happen this week.

Hi I have not forgotten about you. The person who has the definitive answer seems to be on vacation or otherwise not available right now. I am still trying.

I have just been told: Microsoft will support Soundwire (SDCA) as inbox audio driver in the near future. That work is ongoing. It is recommended that you join "SDCA working group meetings" for the latest information. Thus, I don't think it is beneficial for us (DMF Team) to support that in a Module or in DMF directly. Of course, you are welcome to write your own Soundwire related DMF Module(s) if you think that is beneficial to your project.

I will close this issue for now. If you have more questions related to this or any other issue, please create an issue, reply to this thread or send an email to [email protected].
