Abstract
An electronic device includes a processor that executes a guest operating system; a memory having a guest portion that is reserved for storing data and information to be accessed by the guest operating system; and an input-output memory management unit (IOMMU). The IOMMU writes, in the guest portion, information into guest buffers and/or logs used for communicating information from the IOMMU to the guest operating system. The IOMMU also reads, from the guest portion, information in guest buffers and/or logs used for communicating information from the guest operating system to the IOMMU.
