  • Patent number: 9785597
    Abstract: A data processing system includes a main storage, an input/output memory management unit (IOMMU) coupled to the main storage, a peripheral component interconnect (PCI) device coupled to the IOMMU, and a mapper. The system is configured to allocate an amount of physical memory in the main storage and the IOMMU is configured to provide access to the main storage and to map a PCI address from the PCI device to a physical memory address within the main storage. The mapper is configured to perform a mapping between the allocated amount of physical memory of the main storage and a contiguous PCI address space. The IOMMU is further configured to translate PCI addresses of the contiguous PCI address space to the physical memory address within the main storage.

  • Patent number: 9716618
    Abstract: A scheduler may run a script. The script may have a plurality of configuration commands for a network device. A first configuration command of the plurality of configuration commands may be called to begin. A script engine may determine whether a termination request has been received. The script engine may run the first configuration command when it is determined the termination request is not received. While the first configuration command is running, the script engine may receive the termination request. Instead of terminating immediately upon detection of a termination request, the first configuration command may complete.
