[vfio-users] (good) working GPU for passthrough?

[Georgios Amanakis]

I am using an Asus DUAL-GTX1060-O6G which doesn't suffer from the reset
bug. With the usual workarounds, I have never suffered Error 43 (using
either the official NVIDIA driver in Windows, or Asus own driver). I
believe the necessity of the ACS patch depends on the motherboard and the
underlying IOMMU groups. I am using a workstation X9SRA where every PCI-e
slot sits alone in its IOMMU group (admittedly old, based on chipset C602,
X79 era) and never had any problems passing through the aforementioned GTX
1060, or the MSI GT 710 2GD3H LP (low-end).

root complex hierarchy". Selection of the chipset type Q35 in the
virt-manager upon creation does not seem to work with UEFI type of firmware
(as recommended for vfio passthroug). Or perhaps I should have downloaded a
more recent Tianocore UEFI firmware for my virtual machines?
