Original Abstract Submitted
Systems and methods for efficient peripheral device software request queue shadowing for virtual machines can include creating a virtual machine and assigning a peripheral device to it. They can also include assigning, to the peripheral device, a first process address space identifier (PASID) associated with a shadow memory buffer and a second PASID associated with a device data buffer. They can further include causing a host input/output memory management unit (IOMMU) to identify a software request in the shadow memory buffer, and fetching, from the shadow memory buffer, the software request and a guest memory address of data requested to be accessed. They can also include, causing the host IOMMU to identify the data in the device data buffer, and transmitting the data, from the guest memory, to the peripheral device.
