Hi Daniel and Jerome, I know I won't be able to convince you but I want to say that I think your arguments for full userspace open source are not really technical. IMHO, an open-source, thin runtime that provides code to operate ALL the uAPI the driver exports + commitment to only using this

Hi all, Top post, because new argument. There's lots of really good technical arguments for having the userspace component of a driver stack that spans both kernel and userspace open too. For me, that's not really the important argument. I care about open source, I'm not interested in blobs
