It seems like Qualcomm ought to release open source user space code that programs the DMA engine and does some useless example computation. That wouldn't let people do deep learning techniques without using Qualcomm's proprietary code, but would let people verify that the driver and device are harmless.

I proposed that, and was rejected. GregKH wants the actual library we use. I'm running it up the chain to figure out what we can do, but I expect it to take time.

Has such dummy user space code already been released? I guess it could still be useful for people using kernel code not merged by Greg KH. I heard rumours that not everyone uses "pure upstream" kernel code all the time (unbelievable, I know)

Maybe that limited but non-zero experience could even provide some useful lessons for all parties involved, who knows.
