Hi Androme,Working good on my system with AMD 3900X (ondemand governor) on X570 system with IOMMU and SR-IOV.
Using last i40e and iavf drivers
Command line: BOOT_IMAGE=/boot/vmlinuz-5.15.30-2-pve root=/dev/mapper/pve-root ro quiet amd_iommu=on iommu=pt kvm_amd.npt=1 kvm_amd.avic=1 nmi_watchdog=0 mitigations=off
Have a good day.
If you have free time to explain,
What are these grub/efi command that you've listed:
- iommu=pt (I have a vague idea but...)
- kvm_amd.npt=1 && kvm_amd.avic=1 (any intel compatible lines?)
I could look easily in the doc, but sometime daya to day needs are more relevant.
Thanks a bunch!
