Re: Closed source userspace graphics drivers with an open source kernel component

This is more about initial development stages. We maintain kernel API/ABI for all in-tree drivers, however before we put a driver into mainline, we usually need to redo the crazy interfaces that vendors have come up with. Like 32/64 alignment, passing userspace addresses into the kernel, passing phy addresses to userspace etc. If the userspace binary is closed that process becomes next to impossible.

My 2 cents: I think we should leave the onus of fixing the userspace to work with the sane kernel API with the entity trying to get their drivers into the kernel. I think it's a better approach (as in, more likelihood of getting device support) than saying, we will only allow fully open sourced kernel drivers.
