[Qemu-devel] Are there any IOMMU emulation in QEMU for x86 platform

[Jiang, Yunhong]

Hi, all
        I noticed there are several patchset has been sent out about IOMMU 
emulation like 
http://lists.gnu.org/archive/html/qemu-devel/2011-10/msg03764.html, 
http://lists.gnu.org/archive/html/qemu-devel/2011-01/msg03196.html . Also I 
noticed that PPC platform has IOMMU emulation support in QEMU already. Are 
there any plan to support IOMMU emulation in QEMU for x86 now? 

        And also, does it requires the real host platform have the IOMMU to 
support the QEMU IOMMU emulation? Or it will be a purely software emulation?

Thanks
