The tool retrieves a first and a second instruction, which have previously been proven to compute a mathematically correct result when executed separately. The tool defines driver input functions for issuing instructions to the two logic design copies.

Abstract: A computing device may split a translation table used when performing a DMA operation into two different translation tables. To split the translation table, the computing device may update the registers in the IOMMU to include pointers to the two different translation tables. For example, the IOMMU may update one register to point to the same starting address as the original translation table but assign a shorter length (i.e., fewer entries) to that table. The extra entries may then be used to form the other translation table by adding a new pointer to one of the IOMMU registers. The two translation tables may be owned by the same service provider or two different service providers. Alternatively, the computing device may assign the two tables to the same service provider which in turn assigns the tables to respective client devices executed by the service provider.

Abstract: A dynamic DMA window mechanism can resize DMA windows dynamically by increasing one DMA window at the expense of reducing a neighboring DMA window. The dynamic DMA window mechanism can decide to dynamically resize DMA windows based on a request from a system administrator, based on a request by an operating system device driver for an I/O adapter, or based on a performance monitor determining such a resizing would benefit system performance. Once one DMA window has been increased by allocating a portion of a donor DMA window, device drivers for the I/O devices corresponding to the two windows are updated to reflect the new DMA window sizes.

The page map may then be stored during the hibernation process. Before the hibernated virtual machine is resumed, the hypervisor may use the page map to load the hot pages into memory and begin executing the virtual machine.

Abstract: Embodiments described herein identify hot pages associated with a virtual machine that is selected for hibernation or for migration from one computing system to another. For example, before migrating a virtual machine, a hypervisor monitors the entries in a page table (e.g., a virtual translation table) to see what data pages have corresponding entries in the page table. If a data page has a corresponding entry in the page table, the hypervisor may designate that page as hot. A source computing system may transmit the hot data pages to a target computing system which loads the pages into memory. After loading the hot pages into memory, the source computing system may cease executing the virtual machine while the target computing system begins to execute the virtual machine. The rest of the data pages associated with the virtual machine may be transmitted to the target computing system subsequently.
