Can you point out the article you're referring to that mentioned the
Linaro project?

There's nothing I'm aware of that would define what you are asking

in the kernel).  Even the interfaces exported by DRM require user
space code to orchestrate them (i.e., no kernel acceleration in the
purest sense).

cheers,
Jesse
