Re: nvidia gtx 1650 passthru on windows 10

Hello Nuno.

I'm the person who wrote that post. There is nothing that you can do to
pass-thru correctly your nVidia graphic card on a Windows Vm because bhyve
does not have implemented the needed software components,called "line
interrupts for passed through devices". I tried for several months to ask
several bhyve developers if they wanted to write the needed patches,but
none of them have been interested. So now you can only use Linux or FreeBSD
as a VM,not Windows.
