@woxom98179 @cas @katzenmann @bart @jawsh It operates both the wifi and cellular modem for tethering, so I think it should work for wifi too.

It would be interesting to find out how programmable it is. Ultimately I think this kind of thing is the wrong solution (puts control at wrong layers); the right approach would be having an extremely low power core that's not running proprietary chip vendor functionality but as just another core managed by the user's trusted OS kernel, that could even run userspace code when needed (migrating to waking up a full featured core on traps). Hopefully someone doing riscv mobile stuff will eventually get & implement that concept.
