KptnKMan Posted January 26, 2021 Share Posted January 26, 2021 Hi everyone, I've got a working single-GPU passthrough configuration, and I sometimes switch between VMs without issue by stopping the first VM and starting another with a valid config and BIOS. I've been trying to find out how I can regain control of the GPU back to the host Unraid system. I can't seem to find anything in the forum, but maybe I'm using the wrong search terms or something. Essentially, after stopping a passthrough VM, I'm trying to have unraid regain control of the GPU output. Does anyone know how this is achieved? Quote Link to comment
tjb_altf4 Posted January 26, 2021 Share Posted January 26, 2021 The only way I can think it's possible is if the systems is suspended then resumed, forcing a hardware reset. Space invader leveraged something similar with a script to export vbios of the primary GPU a couple weeks ago. Quote Link to comment
KptnKMan Posted January 26, 2021 Author Share Posted January 26, 2021 That's interesting, and thanks for the pointer. Funny, I was poking around and literally just stumbled upon the video and script you mentioned, then saw you mentioning it. Video here: https://www.youtube.com/watch?v=FWn6OCWl63o And the github for the dump script: https://github.com/SpaceinvaderOne/Dump_GPU_vBIOS I thought maybe to mess around with this and see, but my prying eyes did see in the video that SpaceInvaderOne has an "unlock nvidia" script: @SpaceInvaderOne maybe I'm making an assumption here, but is this script to unlock the card for use?
