Hi all I work in the embedded world and am evaluating potential hypervisors and kvm looks suitable for what we want However, I see some old references to 1:1 mapping which would allow a guest to see a PCI device even without an IOMMU Is this currently incorporated into the qemu-0.11 and kvm-88 release?
No.
Is dma=none equivalent to this by any chance or is it only meant for devices that do not use DMA? If 1:1 mapping is not in the tree, is there a reasonable chance that the old patch would work with the latest?
The interest in 1:1 has waned as more hardware now has an iommu, and because 1:1 can only support one guest, and insecurely at that. The patches may work, but are unlikely to make it upsteam now.
