Ok, I consolidated both Hans and Paul into a single document, and added there my comments. I'll be doing the mini-summit report early today at KS based on this.
Just a quick comment:
[snip]
- Laurent Pinchart: ALSA and Media controller
- ALSA folks thought of using Media controller for pipeline control but miss
features: - dynamic creation/removal of MC entities; - lack of a way to store value pairs.
ALSA entities would need to be added and removed at runtime: DSP firmware decides what kind of entities exist
E.g. equalisers could be created as needed
ALSA already has APIs for that
If I'm not mistaken ALSA doesn't have that API yet, but they're planning to add it.
Detailed sub-system specific data is needed:
ALSA: what kind of features the entity has
Proposal: binary blob specific to entity that contains key: value
pairs --- this could be used in V4L2 as well
