Excellent!
Is there any optimization (or indeed implementation) work being done
here by anyone in the MMWG itself (i.e. excluding Tom)?
Tom willingly jumped on this work when we didn't have anyone else and has done a great job. Mans has been advising as needed. I see no need to take it away from Tom just because he isnt officially in the MMWG.

That's correct -- even if Snowball lacks an IOMMU for the hardware
codecs, it should be able to use CMA to get access to a contiguous area
and the dma-buf API should work for it. Who is working on this?
Jesse and I are discussing who does what, but from the mmwg I would like Benjamin to work on this, probably with someone else from his team.

Nice -- what are the results looking like?

Can you get the requirement laundry list polished up a little bit and
sent to the TSC for feedback if any topics there look worth pursuing
further into requirements?
There are only 3 left from the list that are bounded enough to consider:
1) Compressed data api into ALSA - driver specific kernel work and ALSA/ASoC plumbing, prob not a good fit for mmwg yet
2) ALSA port of ST-E drivers - also prob not a good fit for mmwg, already proposed as a possible requirement for the new STG team in that mail thread
3) End to end audio tests for integration - new proposal by Alexander, blueprints are already created, investigation underway, but I can write up a papyrs page for it if we need to take it in front of the TSC
