Abstract: To pin pages of a virtual memory space allocated to a virtual machine (VM) controlling an input/output (I/O) device of a system, an input/output memory management unit (IOMMU) driver of the VM first loads pinning commands into a queue that indicate whether each page in the virtual memory space is to be pinned or unpinned. A hardware-based IOMMU of the system then retrieves the pinning commands from the queue and based on the retrieved commands, provides data to a hypervisor of the system indicating which pin commands are to be performed. Using this data provided by the hardware-based IOMMU, the hypervisor pins and unpins the pages of the virtual memory space.

Abstract: A method of preloading address translation information directly into cache memory of an IOMMU includes storing the address translation information in a register set of memory management input/output registers of an input-output memory management unit and loading the address translation information into cache memory of the input-output memory management unit. The address translation information includes a virtual address and a corresponding physical address of system memory of a computing system. The address translation information is sent by software being executed by a processor of the computing system. The address translation information is received directly from the processor.
