Oh sorry. I'm not very familiar with iommu code (yet). My understanding is iommu_domain_init() is called unconditionaly by arch_domain_create() so that platform_ops is initialized. iommu_(un)map_page() checks iommu_enabled and whether platform_ops is initialized. Thus iommu_(un)map_page() manipulates iommu page table even for PV domain. Clearly I'm missing something important. Could you enlighten me? thanks, -- yamahata _______________________________________________ Xen-ia64-devel mailing list Xen-ia64-devel@lists.xensource.com http://lists.xensource.com/xen-ia64-devel
