AMD Ryzen 1700x build, per some advice on here, I went ahead and bought another video card. Since the Ryzen CPU doesn't have onboard graphics, I'm having a bit of trouble getting them to passthrough correctly.
First PCIe 16x slot: AMD Vega 56
Second: Nvidia GTX 1070Ti
The second card passthrough works just fine, and is a huge success; however, if possible, I'd like to make use of the first slot as well. I've added:
vfio-pci.ids=1002:687f,1002:aaf8
to my syslinux.cfg, but it doesn't seem to make a difference. Have tried SeaBIOS and OVMF. Is it worth trying another nvidia card in the first slot? I thought AMD cards were supposed to "just work"? I've also tried another AMD card, the RX 580 in this slot, couldn't get that to work either. Ideas greatly appreciated!
