I don't think this is true at all - nouveau is probably the best example. nouveau reverse engineered a userspace stack for one of these devices. How much further ahead would they have been by now if they had a vendor supported, fully featured, open kernel driver to build the userspace upon? > open up your hw enough for that, I really don't see the point in > merging such a driver, it'll be an unmaintainable stack by anyone else > who's not having access to those NDA covered specs and patents and > everything. My perspective from RDMA is that the drivers are black boxes. I can hack around the interface layers but there is a lot of wild stuff in there that can't be understood without access to the HW documentation. I think only HW that has open specs, like say NVMe, can really be properly community oriented. Otherwise we have to work in a community partnership with the vendor.
