Subject[PATCH/RFC 0/5] HW accel subsystem
Date
Per discussion in on the Habana Labs driver submission
(https://lore.kernel.org/lkml/20190123000057.31477-1-oded.gabbay@gmail.com/),
there seems to be time to create a separate subsystem for hw accellerators
instead of letting them proliferate around the tree (and/or in misc).

There's difference in opinion on how stringent the requirements are for
a fully open stack for these kind of drivers. I've documented the middle
road approach in the first patch (requiring some sort of open low-level
userspace for the kernel interaction, and a way to use/test it).

Comments and suggestions for better approaches are definitely welcome.
