intel_debug: introduction: Update for pathnames for IPC4 support #476

Closed ujfalusi closed 8 months ago

ujfalusi commented 9 months ago

SOF supports platforms from Tiger Lake with IPC4, update the docuementation accordingly.

Update the MTL/LNL topology path to follow a generic pattern and add a note about the need for a symlink for the old path to retain backwards compatibility with released kernels.

Thanks! So this should be done with the 2023.12 release then? I've released the debian package for that and haven't implemented the symlink from sof-ace-tplg to sof-ipc4-tplg there. I'm a bit confused by the backwards compatibility comment as, to my knowledge, Meteorlake audio isn't working with currently released kernels (pre 6.7) so I'm wondering if this is really a no-op? Let me know if I need to update the deb package or if it's just something that can be done for the next release.

As a side note, audio with 2023.12 is running on my Meteorlake X1 Carbon G12, with a 6.7 rc7 kernel, well (only just got the machine yesterday though....so still setting it up and playing with it)

So no change in the short term. If we need to have symlinks, those need to be in sof-bin releases first.

We also need to solve the issue of platform specific tplgs first before we can merge sof-ace-tplg and sof-ipc4-tplg -> https://github.com/thesofproject/sof/issues/8683
