Unfortunately these settings don’t work for me. I just tested them on Fedora 28 (Kernel 4.17.12). Hopefully the OP has better luck.
I don’t want to hi-jack the thread, but if this is actually the same issue as the OP is experiencing I am happy to run any tests because I have a spare machine with the R9 360 in it and can run the tests pretty quickly and report the results.
ok so ive removed the 390 and installed the nvidia card, installed the proprietary drivers and it seems to work, now I need to find a distro I can use for gpu passthrough into a windows virtual machine using the r9 390 for linux and n evga 1080ti ftw3 for windows, that wont crash
you’re gonna have a hard time trying to switch around the host card in a live system.
i think you misunderstand. the primary os will be linux using 1 card and a virtual machine with a separate card being passed through to a virtual machine. 2 cards, 2 operating systems, no switching
ah, i figured you’d want to do handoff since you said you were using nvidia on the host system.
no that would be stupid, and the host machine will use a amd card with an nvidia card being for windows, the 1080ti is a good choice because of the 10-15% performance loss
not necessarily, you could actually use nvidia-xrun so you always have the best performing card available,
Like I said, though, I just misread your post.
