Rather than do this in each SMMU driver, it's much cleaner to allow the default domain to be configured to be something other than DMA. This patch series implements a command-line option to configure the default domain type. Currently, it supports "dma" and "identity" which is sufficient for the passthrough use-case. [Fix] The following patch series in linux-next adds this support to the kernel. 4a8d8a14c0d0 arm64: dma-mapping: Only swizzle DMA ops for IOMMU_DOMAIN_DMA fccb4e3b8ab0 iommu: Allow default domain type to be set on the kernel command line beb3c6a066bf iommu/arm-smmu-v3: Install bypass STEs for IOMMU_DOMAIN_IDENTITY domains 67560edcd8e5 iommu/arm-smmu-v3: Make arm_smmu_install_ste_for_dev return void 61bc671179f1 iommu/arm-smmu: Install bypass S2CRs for IOMMU_DOMAIN_IDENTITY domains 0834cc28fa56 iommu/arm-smmu: Restrict domain attributes to UNMANAGED domains To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1688158/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
