[PATCH v2 2/5] iommu/arm-smmu: Install bypass S2CRs for IOMMU_DOMAIN_IDENTITY domains

In preparation for allowing the default domain type to be overridden, this patch adds support for IOMMU_DOMAIN_IDENTITY domains to the ARM SMMU driver. An identity domain is created by placing the corresponding S2CR registers into "bypass" mode, which allows transactions to flow through the SMMU

[PATCH v2 1/5] iommu/arm-smmu: Restrict domain attributes to UNMANAGED domains

The ARM SMMU drivers provide a DOMAIN_ATTR_NESTING domain attribute, which allows callers of the IOMMU API to request that the page table for a domain is installed at stage-2, if supported by the hardware. Since setting this attribute only makes sense for UNMANAGED domains, this patch returns

[PATCH v2 5/5] iommu: Allow default domain type to be set on the kernel command line

The IOMMU core currently initialises the default domain for each group to IOMMU_DOMAIN_DMA, under the assumption that devices will use IOMMU-backed DMA ops by default. However, in some cases it is desirable for the DMA ops to bypass the IOMMU for performance reasons, reserving use of translation

[PATCH v2 4/5] iommu/arm-smmu-v3: Install bypass STEs for IOMMU_DOMAIN_IDENTITY domains

In preparation for allowing the default domain type to be overridden, this patch adds support for IOMMU_DOMAIN_IDENTITY domains to the ARM SMMUv3 driver. An identity domain is created by placing the corresponding stream table entries into "bypass" mode, which allows transactions to flow through

[PATCH v2 0/5] Implement SMMU passthrough using the default domain

Hi all, This is version two of the patches previously posted here: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-January/481275.html I've addressed the review feedback I receive there, but the main change is that the SMMUv3 driver now handles passthrough domains independently of

[PATCH v2 3/5] iommu/arm-smmu-v3: Make arm_smmu_install_ste_for_dev return void

arm_smmu_install_ste_for_dev cannot fail and always returns 0, however the fact that it returns int means that callers end up implementing redundant error handling code which complicates STE tracking and is never executed. This patch changes the return type of arm_smmu_install_ste_for_dev to
