Here is a draft patch series for amd-iommu device. It will implement
amd-iommu device and its attributes: intremap, device-iotlb, xtsup.
However, its secret device AMDVI-PCI will occupy a PCIe slot and cause
VM failed to start:
Domain XML:
<domain type='kvm'>
...
<video>
<model type='virtio' heads='1' primary='yes'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/>
</video>
<iommu model='amd'/>
...
</domain>
➜ ~ virsh create /tmp/fedora.xml
error: Failed to create domain from /tmp/fedora.xml
error: internal error: QEMU unexpectedly closed the monitor (vm='fedora'): 2024-09-27T07:55:46.132886Z qemu-system-x86_64: -device {"driver":"virtio-vga","id":"video0","max_outputs":1,"bus":"pcie.0","addr":"0x1"}: PCI: slot 1 function 0 not available for virtio-vga, in use by AMDVI-PCI,id=(null)
I'll update the series when QEMU fixes the blocker.
Han Han (5):
qemu_capabilities: Introduce QEMU_CAPS_AMD_IOMMU
qemu_capabilities: Introduce QEMU_CAPS_AMD_IOMMU_INTREMAP
qemu_capabilities: Introduce QEMU_CAPS_AMD_IOMMU_DEVICE_IOTLB
qemu_capabilities: Introduce QEMU_CAPS_AMD_IOMMU_XTSUP
qemu: Add suppport for amd-iommu device and xtsup attrib
