Has anybody managed to successfully pass through a GPU to a KVM/Qemu VM on an Asus Rog Zenith II Extreme Alpha TRX40 board?
I've has success with the Asrock Creator TRX40 board, but this new one is not working out so well.
Linux just refuses to use anything other than software bounce buffers for DMA, and no DMAR in sight.
I've tried every combination of kernel command line settings and related BIOS setting that I can find, but nothing seems to matter.
Rather than go through every combination I've tried, I figured I'd first ask if anybody managed to get it to work, and if so, what were the related BIOS settings and/or kernel command line used that ended up working for them.
Thanks!
