How does memory mapped I/O (MMIO) work on ARM architectures?

In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) that connects a direct-memory-access–capable (DMA-capable) I/O bus to the physical memory. Like a traditional MMU, the IOMMU maps device-visible virtual addresses (also called I/O virtual … Meer weergeven The SMMU provides the capability of accessing the physical memory by using the IOVA visible to the device. In the system … Meer weergeven One of the main functions of the IOMMU is to prevent the device from directly using the PA when accessing the memory in DMA mode. Therefore, the IOVA is generated. … Meer weergeven All IOMMU-related drivers are stored in the drivers/iommu directory of the kernel. The latest SMMUv3 driver is arm-smmu-v3.c. The struct arm_smmu_devicestructure manages the key … Meer weergeven The main function of the IOMMU is to provide the mapping from the IOVA to the PA for the device to access the physical memory. In this way, the device does not directly use the PA to access the memory, which is … Meer weergeven WebThe IOMMU handles this re-mapping, allowing the native device drivers to be used in a guest operating system. In some architectures IOMMU also performs hardware interrupt re-mapping, in a manner similar to standard memory address re-mapping. Peripheral memory paging can be supported by an IOMMU.
