Review comment: Thanks @manupa-arm @hogepodge We currently do not have any plans for adding hardware into a cloud. Ethos-U is licensed as a part of Arm’s IP portfolio. I expect SoCs and boards containing Ethos-U from the broader Arm ecosystem in due course but I’m not at liberty to speculate on time lines. As part of the Ethos-U upstreaming work and the first PR that has been merged for docker images, Arm has contributed a reference system, what we call Fixed Virtual Platforms for the Corstone-300 subsystem in the TVM CI. We believe this is sufficient for continually testing the correctness of the Ethos-U port and indeed for testing correctness on Cortex-M. The value of hardware based correctness testing is debatable beyond testing that comes from the simulator and is beyond the scope of this RFC or Pull Requests. -- This is an automated message from the Apache Git Service.
