H A D | q35.h | a52a7fdf Sat Aug 16 00:55:40 CDT 2014 Le Tan <tamlokveer@gmail.com> intel-iommu: add Intel IOMMU emulation to q35 and add a machine option "iommu" as a switch Add Intel IOMMU emulation to q35 chipset and expose it to the guest. 1. Add a machine option. Users can use "-machine iommu=on|off" in the command line to enable/disable Intel IOMMU. The default is off. 2. Accroding to the machine option, q35 will initialize the Intel IOMMU and use pci_setup_iommu() to setup q35_host_dma_iommu() as the IOMMU function for the pci bus. 3. q35_host_dma_iommu() will return different address space according to the bus_num and devfn of the device.
