It would have been nice to at least find a diff stat here. ... Do we really need to coordinate this series cross-subsystem? Can we first apply the API, then have each of the subsystems adapted separately? Does the change-over all need to happen concurrently? If the latter is the case, is this set bisectable?

I would suggest to merge it via irq subsystem but I leave the logistics
to tglx.

Could you answer by other questions too please?

I don't think that I can answer them. I said I leave the logistics to tglx. This can go via one merge via irq. This can also go differently i.e. feature branch on top of 5.17-rc1 (with 1/7) which is merge into each subsystem and then the "feature" on top. Either way it remains bisect-able since each driver is changed individually. There is no need to merge them in one go but since it is that small it probably makes sense. But I don't do the logistics here. Sebastian

I'm not asking you about merge strategies. We can handle that without issue. > Either way it remains bisect-able since each driver is changed > individually.

So there aren't any hard dependencies between the driver changes? Only the drivers are dependent on the API. So, if we choose to do so, we can merge the API and then subsequently add the users one by one into their respective subsystem, in any order. This would save on creating an immutable topic branch which we all pull from. What is your preference Thomas?

Correct. #2 - #7 depend on #1. The order of #2+ is not relevant.
