    Abstract: A method and system for processing data are disclosed. A processor, in response to executing a software program, may write an entry in a work queue. The entry may include an operation, and a location of data stored in an input buffer, and a location in an output buffer to write processed data. The processor may also generate a notification that at least one entry in the work queue is ready to be processed. The data transformation unit may assign the entry to a data transformation circuit, and retrieve the data from the input buffer using the location. The data transformation unit may also perform to the operation on the retrieved data to generate updated data, generate a completion message in response to completion of the operation, and store the updated data in an output buffer. An interface unit may relay transactions between the processor and the data transformation unit.

    Abstract: Embodiments of input/output hub unit are disclosed for aggregating interrupts received from multiple endpoint devices. The input/output hub may include an interface unit and one or more communication units. Each communication unit may be configured to receive messages from a corresponding endpoint device. The interface unit may be configured to update a first pointer within a first data structure responsive to a request from a given one of the communication units. The interface unit may be further configured to stored data in a second data structure responsive to updating the first pointer, reading a second pointer and the first pointer, and sending an interrupt responsive to a determination that the first and second pointers are equal.

    Abstract: An apparatus and method for controlling a virtualized endpoint device are disclosed. A processor may be configured to execute instructions included in multiple execution threads. A first device may be configured to perform multiple command and data functions, and a communication unit may include a first port coupled to the first device via a first link and be configured to send instructions from the processor to the first device via the first link using a first communication protocol. The processor may be further configured to execute first and second sets of commands included in respective execution threads. The first set of commands may be associated with the plurality of command functions and the second set of commands may be associated with the plurality of data functions.

    Abstract: A switched fabric hierarchy (e.g., a PCIe hierarchy) may utilize hardware, firmware, and/or software for filtering duplicative or otherwise undesirable correctable error messages from reaching a root complex. An operating system of the root complex may detect a persistent stream or storm of correctable errors from a particular endpoint and activate filtering of correctable errors from that endpoint. A filtering device may receive filtering commands and parameters from the operating system, implement the filtering, and monitor further correctable errors from the offending device. While an offending device is being filtered, correctable error messages from the offending device may be masked from the operating system, while correctable error messages from other devices in the switched fabric hierarchy may be transmitted. At such time as the filtering device may detect that conditions for ending filtering of a device are met, the filtering device may cease filtering of the offending device and return monitoring responsibilities to the operating system.
