PCIe passthrough

Hello,

I’m trying to do PCIe passthrough from host to Qemu-KVM.

I do see the WiFi card being added to an IOMMU group when booting up

But when trying to take control of the device I don’t see it available nor IOMMU compatible. lspci doesn’t return any IOMMU/SMMU capabilities when you run lspci -v | grep “IOMMU”

At the same time, when trying to list available PCI devices to use with virsh, none are displayed:

Even trying to use vfio-pci to take control of the PCIe doesn’t work, as explained in this post (ACS override patch to isolate target device from IOMMU group)

I’m also getting that same error, but as pointed out above, both PCI’s are being assigned to an IOMMU group.

Is there something missing on both approaches to make this work?

Appreciate the help
