State of GPU pass through hardware

Looking for some insight to recommended graphics cards for host and guest. I currently have a Vega and last I heard they had issues reinitializing after shutdown when used for the guest.

Also are there still issues with Threadripper systems?

Yes to Threadripper, Yes to Vega last I heard.

If you need a reliable USB controller, the Renesas uPD720202 will not fail you.

Well that’s a bummer. The wait continues I suppose.

From what I read nvidia is good for host, and ati for guest except vega?

AMD cards are either 100% issue free or have 1 of 2 kinds of reset bug, nvidia cards will always give you bullshit to some extent unless you spring for the quadro

TR has some fixing involved.

Awesome, that’s a fantastic resource. Thanks for sharing.

to answer your question, there are both client and guest side fixes for both types of reinit bug, and apparently kernel fixes in the newer kernels.
