Georg Posted November 21, 2019 Share Posted November 21, 2019 (edited) Hi all, Unfortunately I don't know any further and google could not help... In the bios I have enabled SVM Mode (CPU configuration) as well as SR-IOV (Onboard device configuration) but Unraid still gives me an IOMMU disabled: Is there an option called "IOMMU" I have to enable additionally? If yes where? I have also noticed that there are no IOMMU groups shown in system devices (this may happen after unraid recognize IOMMU as enabled?) Thank you for helping in advance!

hammsandwich Posted December 28, 2020 Share Posted December 28, 2020 Has anyone had luck with PCI passthrough and IOMMU groups on these new BIOS's? I head there were issues. I have a Win10 VM with multiple PCI passthrough devices, including NVMe, NVIDIA GPU, and onboard USB controller (with ACS patch). Quote Link to comment
jad3 Posted May 1, 2021 Share Posted May 1, 2021 Many Many thanks to Georg for the location of the iommu settings. I just loaded up the newest 4.7 bios on an x470 Taichi Ultimate and I'm further than I was before with the prior iterations of bios. Trying to pass through an NVIDIA gpu - thanks for the settings Georg! Quote Link to comment
