Agreed, but I think we should go further than this and work towards a
subsystem across companies for machine learning and neural networks
accelerators for both inferencing and training.
We have support for Intel habanalabs hardware in drivers/misc, and there are
countless hardware solutions out of tree that would hopefully go the same
way with an upstream submission and open source user space, including
- Intel/Mobileye EyeQ
- Intel/Movidius Keembay
- Nvidia NVDLA
- Gyrfalcon Lightspeeur
- Apple Neural Engine
- Google TPU
- Arm Ethos
plus many more that are somewhat less likely to gain fully open source
driver stacks.
