Because I haven't seen you to acknowlege that the current direction we're moving to is that we're trying to move away from Nouveau and start over with a new GSP-only solution. Instead you propose a huge architectural rework of Nouveau, extract a core driver from Nouveau and make this the long term solution. > > I have no intention of becoming involved in your project or > nouveau.

First, Nova isn't a different project in this sense, it's the continuation of Nouveau to overcome several problems we have with Nouveau. Second, of course you have the intention of becoming involved in the Nouveau / Nova project. You ask for huge architectural changes of Nouveau, including new interfaces for a VFIO driver on top.

So, if you want to do a major rework in Nouveau (and hence become involved in the project) we have to make sure that we progress things in the same direction. How do you expect the project to be successful in the long term, if the involved parties are not willing to agree at a direction and common goals for the project? Or is it that you are simply not interested in long term? Do you have reasons to think that the problems we have with Nouveau just go away in the long term? Do you plan to solve them within Nouveau? If so, how do you plan to do that? > > > But you're not even considering it, and instead start with a counter proposal. > > This isn't acceptable to me. > > I'm even agreeing to a transition into a core driver in Rust, someday, > when the full community can agree it is the right time. > > What more do you want from me? I want that the people involved in the project seriously discuss and align on the direction and goals for the project in the long term and work towards them together.
