Agreed. This should also be the default if not dma=xxx is specfied and a capable IOMMU is found. > Or rather > > dma=iommu > dma=none (1:1 mapping, or dma-less devices, or I'm Feeling Lucky) > dma=cooperative (paravirt) What does the 'cooperative' mean? I assume you are thinking of PVDMA-without-IOMMU, but in that case the name is misleading, since you can do cooperative (PVDMA) just fine with an IOMMU. Perhaps "dma=itrusttheguest", since with PVDMA0-without-IOMMU the guest is trusted to not screw up the system?
