ACRN support for AI Accelerator USB stick


Zou, Terry
 

Hi Feng.Pan, really good idea to try Movidius USB stick in virtual machine on top of ACRN, that would be a wonderful scenario to run AI workload with OpenVINO in one VM, both Linux or Windows , and other time critical workload in other VM, e.g., RTVM :)
Basically for ACRN, AI USB stick is an USB device in SOS, you can either pass-through this device to post-launch Linux/Windows VM directly or pass-through USB host controller to guest(corresponding USB slave device will also pass-through to same guest VM).  
But actually we did not try such Movidius USB stick yet, if you have it on-hand, please try it, and let us know if any specific issues. thanks.

Best & Regards
Terry

Hello everyone,

 

I am considering an experimental setup, using ACRN Hypervisor on top of Tiger Lake Platform.

 

I have seen that ACRN supports USB pass-through. How will it behave, if I want to use an AI USB stick (e.g. Intel Movidius USB stick)? How will it work with a multi-VM environment?

 

Thank you and best regards,

Feng. PAN
