    I suspect a lot more is done in kernel space by the NVIDIA driver because of their need to share that driver codebase with OSX and Windows (on Windows in particular a lot more driver stuff is done in kernel AFAIK)

    It looks as DRM interface to DMA-BUF, shared by drivers. Almost certainly it won't impose GPL requirement for usage, and so lets NVIDIA blob use DMA-BUF implicitly. It won't allow use cases of DMA-BUF with proprietary drivers, though. At least while devs remain stubborn

    Maybe NVIDIA should open their kernel part, like mobile GPU people did. Clever driver work is mostly done in userspace (although it would still be very useful to nouveau folks for easier RE).

    All this appears to do is consolidate code that was duplicated between the nouveau/radeon/exynos drivers.

    So the intro about the binary driver is a red herring.

    And does it have any drawback to using DMA-Buff like initially intended?

    Does this solve the no nvidia blob access issue? Or is this something else entirely?
