Also I would like to see a notice printed into the kernel log that we instantiated the driver on a NPU core and show it as experimental, as I'm not sure if our UAPI covers all things that are needed for NPU operation. I wouldn't want to break our basic assumption that the kernel driver is in charge of cleaning write caches when switching contexts and event management, which might require some UAPI additions to work with the NPU accelerator programming model.

This is a compute-only module marketed towards AI and vision acceleration. This particular version can be found on the Amlogic A311D SoC. The feature bits are taken from the Khadas downstream kernel driver 6.4.4.3.310723AAA.
