  • Extensible configuration methods for optical networking apparatuses with multiple multi-protocol optical networking modules
    Patent number: 8914509
    Abstract: An API including a registration function and a configuration function, is provided to an optical networking apparatus to facilitate registration of configuration specification delimiter pairs by service routines of function blocks of multi-protocol optical networking modules (MPONM), and extraction of configuration specifications for the function blocks from a configuration specification input set using the registered configuration specification delimiter pairs. In one embodiment, the configuration function also receives current configuration of the function blocks, and merges the received current configurations of the function blocks into a configuration specification output set, separating the merged configuration specification using the registered configuration specification delimiters.

  • Translation data prefetch in an IOMMU
    Patent number: 7793067
    Abstract: In an embodiment, a system memory stores a set of input/output (I/O) translation tables. One or more I/O devices initiate direct memory access (DMA) requests including virtual addresses. An I/O memory management unit (IOMMU) is coupled to the I/O devices and the system memory, wherein the IOMMU is configured to translate the virtual addresses in the DMA requests to physical addresses to access the system memory according to an I/O translation mechanism implemented by the IOMMU. The IOMMU comprises one or more caches, and is configured to read translation data from the I/O translation tables responsive to a prefetch command that specifies a first virtual address. The reads are responsive to the first virtual address and the I/O translation mechanism, and the IOMMU is configured to store data in the caches responsive to the read translation data.

  • Method and apparatus for translating guest physical addresses in a virtual machine environment
    Patent number: 7124273
    Abstract: A method and an apparatus are used to efficiently translate memory addresses. The translation scheme yields a translated address, a memory type for the translated address, and a fault bit for the translation.
