1. It was enabled VT-d/AMD-Vi in BIOS

2. It also set /etc/default/grub as follow

GRUB_CMDLINE_LINUX_DEFAULT="radeon.blacklist=1 quiet splash intel_iommu=on pci-stub.ids=1002:679a,1002:aaa0"

3.And passthrough wx 4100 to win10 virtual machine, then win10 was hung up

4. Check vfio

[root@node-19 ~]# lsmod | grep vfio
vfio_pci 41312 1
vfio_iommu_type1 22300 1
vfio 32695 5 vfio_iommu_type1,vfio_pci
irqbypass 13503 10 kvm,vfio_pci

 

Is there any good advice?

 

Best regards
