Abstract: A model in which filter drivers are managed to receive callbacks for I/O requests in which the filter drivers have registered an interest. Per-volume instances of filter drivers register with a filter manager for pre-callbacks (for I/O to the file system) and post-callbacks (for I/O from the file system), and identify which I/O requests (e.g., create, read, write) they are registering to receive callbacks. The filter manager orders the instances for callbacks. When an I/O request is received, the filter manager converts the I/O request to callback data and calls the interested filters in the callback order, whereby the filter instances can process the I/O data. As the request returns from the file system, filters desiring post callbacks are called in the reverse order. Efficient context management for the filters and other functions, such as non-reentrant file I/O, are also provided by the model.

Abstract: A network device receives data packets from a network adaptor. A low latency memory has a first read/write performance. A high latency memory has a second read/write performance that is slower than the first read/write performance of the low latency memory. An interface controller uses an address check circuit and values stored in registers to determine whether a read or write operation relates to header portions of the data packets. The interface controller stores header portions of the data packets in the low latency memory and data portions of the data packets in the high latency memory. The registers include base address, buffer pool size, maximum individual buffer size, and header size registers. Alternately the registers include base address, mask, maximum individual buffer size, and header size registers.

Abstract: A method and system processing non-data frames in a host bus adapter with a main processor and a first processor coupled to a host system and fibre channel is provided. The method includes, examining non-data frames; storing non-data frame information; notifying the first processor of non-data frames; and processing non-data frames without generating an interrupt for the main processor. The host bust adapter includes a fibre channel module (“FPM”) with a state machine, wherein the fibre channel module receives and examines the non-data frames and stores non-data frame information in a FIFO. The FPM notifies the first processor that the non-data frames have been received.

Abstract: The address of a data packet to be transferred from a memory to a network interface card within a direct memory access (DMA) is checked. First of all, the address of a descriptor corresponding to the data packet is read from the memory, wherein the descriptor contains information of the address of the data packet. Then, whether the address of the descriptor complies with a certain rule is determined. If the address of the descriptor does not comply with the certain rule, an interrupt signal is asserted to a processor to perform a corresponding interrupt service in order to re-read the address of the descriptor.

Abstract: A method and apparatus for communicating commands and/or data between two different time domains. In one embodiment, multiple memory commands are placed into one or more FIFOs in a manner that specifies the delays that must take place between execution of the different commands. Along with the commands, delay information is placed into the FIFOs, specifying the number of clock cycles, or other form of time delay, that must elapse between execution of a command and execution of a subsequent command. This delay information is used to delay the execution of the subsequent command for the specified time period, while minimizing or eliminating any excess delays. Cue information can also be placed into the FIFOs with the commands to specify which commands must wait for other commands before beginning execution. The delay and cue information is determined and created in the time domain that initiates the transfers. The delays and cueing are executed in the other time domain.

Abstract: The packets of the sequence are stowed away in a packets memory organized as a stack, in association with respective processing labels. The processing label associated with each packet extracted from the packets memory is examined so as to activate a processing module selected as a function of the label received. The activated module performs an elementary processing of the packet extracted. The elementary processing performed by at least one of the processing modules comprises associating the extracted packet with a label modified in accordance with a labels translation table, the processed packet subsequently being stowed away again in the packets memory in association with the modified label.

Abstract: A host channel adapter configured for outputting packets according to InfiniBand™ protocol is implemented using partitioned link modules configured for performing selected link operations prior to outputting the packets. A pre-link module is configured for ordering work queue entries in an order based on determined service level and virtual lane priorities. The pre-link module outputs the ordered work queue entries to a transport service module configured for generating a transport layer header for the packets based on the respective work queue entries. Once the transport layer headers have been generated, a post-link module is configured for retrieval of the transport layer header and transport data and preparing the transmit data packets for transmission on the network by constructing the link layer fields. The post-link module outputs the transmit data packets based on the ordering and the flow control protocol for the appropriate virtual lanes.
