Hi Paul, On 09/27/2018 03:33 PM, Paul Durrant wrote: This patch removes the implicit domain_crash() from iommu_map(), unmap_page() and iommu_iotlb_flush() and turns them into straightforward wrappers that check the existence of the relevant iommu_op and call through to it. This makes them usable by PV IOMMU code to be delivered in future patches. > This patch adds a helper macro, domu_crash(), that will only invoke domain_crash() if the domain is not the hardware domain and modifies callers of iommu_map(), unmap_page() and iommu_iotlb_flush() to use this should an operation fail. NOTE: This patch includes one bit of clean-up in set_identity_p2m_entry() replacing use of p2m->domain with the domain pointer passed into the function.
