Ubuntu only boots when iommu=soft












0















Ok, so I've been battling with this problem for few weeks now.



I'm currently rocking:




  • fx-8320E


  • GA-970A-DS3P


  • RX-480 4GB



and I've been having a problem with the IOMMU boot.



So, if I try to boot with anything other than the soft mode on iommu in grub, I get stuck on booting, no matter what the amd_iommu setting is set to. iommu=off works fine, but no usb devices are recognised.



Also, I've checked the BIOS and I have enabled SVM and IOMMU for my cpu, and both CPU and the MB support AMD-Vi



If I run dmesg | grep iommu -i I get this output:



[    0.000000] Command line: BOOT_IMAGE=/boot/vmlinuz-4.18.0-16-generic root=UUID=087205d6-21bf-4c57-87d6-3621a0f04b6c ro iommu=soft

[    0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-4.18.0-16-generic root=UUID=087205d6-21bf-4c57-87d6-3621a0f04b6c ro iommu=soft

[    5.003506] AMD IOMMUv2 driver by Joerg Roedel <jroedel@suse.de>

[    5.003507] AMD IOMMUv2 functionality not available on this system


I'm assuming that it's saying that functionality is not available because I'm not running the motherboard iommu, but the software one.



So, I'd like to know if there's anything else I can try or check to fix this "problem" and maybe get a Windows VM running with GPU passthrough.



Thanks in advance.

and the problem is that the iommu=pt iommu=1 don't work for me, as they don't seem to boot.

      I'm assuming that it's saying that functionality is not available because I'm not running the motherboard iommu, but the software one.



      So, I'd like to know if there's anything else I can try or check to fix this "problem" and maybe get a Windows VM running with GPU passthrough.



      Thanks in advance.



      EDIT



      When running virt-host-validate I receive this output:

      and the problem is that the iommu=pt iommu=1 don't work for me, as they don't seem to boot.
