20090086736 | NOTIFICATION OF OUT OF ORDER PACKETS - Methods and apparatus relating to notification of out-of-order packets are described. In an embodiment, data such as a sequence number and a flow identifier may be extracted from a packet. The extracted data may be used to check the extracted sequence number against an expected sequence number and indicate that the packet is an out-of-order packet. Other embodiments are also disclosed. | 04-02-2009 |
20090213732 | Preserving packet order when migrating network flows between cores - In one embodiment, the present invention includes a method for receiving a first packet associated with a first network flow in a first descriptor queue associated with a first hardware thread, receiving a marker in the first descriptor queue to indicate migration of the first network flow from the first hardware thread to a second hardware thread, and processing a second packet of the first network flow following the first packet in order in the second hardware thread. | 08-27-2009 |
20090319705 | COMMUNICATION BETWEEN PROCESSOR CORE PARTITIONS - In an embodiment, a method is provided that may include providing a first address space exclusively and coherently accessible by a first processor core partition in a platform. A second address space may be provided in this embodiment that is exclusively and coherently accessible by a second processor core partition in the platform. Also in this embodiment, a third address space in the platform may be provided that is accessible, at least in part, by both the first and second processor core partitions and may be to permit communication between the first and second processor core partitions of at least one packet and at least one descriptor associated with the at least one packet. The at least one descriptor may indicate, at least in part, one or more locations in the third address space to store, at least in part, the at least one packet. Of course, many alternatives, modifications, and variations are possible without departing from this embodiment. | 12-24-2009 |
20100083259 | DIRECTING DATA UNITS TO A CORE SUPPORTING TASKS - A computer system may comprise a plurality of cores that may process the tasks determined by the operating system. A network device may direct a first set of packets to a first core using a flow-spreading technique such as receive side scaling (RSS). However, the operating system may re-provision a task from the first core to a second core to balance the load, for example, on the computer system. The operating system may determine an identifier of the second core using a new data field in the socket calls to track the identifier of the second core. The operating system may provide the identifier of the second core to a network device. The network device may then direct a second set of packets to the second core using the identifier of the second core. | 04-01-2010 |
20110153893 | Source Core Interrupt Steering - An embodiment of the invention includes (i) receiving a core identifier that corresponds with a processor source core; (ii) receiving an input/output request, produced from the source core, that is associated with the core identifier; (iii) and directing an interrupt, which corresponds to the request, to the source core based on the core identifier. Other embodiments are described herein. | 06-23-2011 |
20130080674 | Source Core Interrupt Steering - An embodiment of the invention includes (i) receiving a core identifier that corresponds with a processor source core; (ii) receiving an input/output request, produced from the source core, that is associated with the core identifier; (iii) and directing an interrupt, which corresponds to the request, to the source core based on the core identifier. Other embodiments are described herein. | 03-28-2013 |
20130339565 | METHOD, DEVICE AND SYSTEM FOR AGGREGATION OF SHARED ADDRESS DEVICES - Techniques and mechanisms for managing resources of an aggregate device which spans multiple physical devices of a computer platform. In an embodiment, an aggregation device coupled to a host bus of the computer platform receives resource information generated by a pre-boot software process of the computer platform. In another embodiment, the aggregation device, based on the received resource information, represents a resource in a first input/output (I/O) device to a host operating system (OS) as residing in the aggregation device, the first I/O device coupled to the aggregation device via a host bus for exchanging communications referencing a shared address space. | 12-19-2013 |

20140089728 | METHOD AND APPARATUS FOR SYNCHRONIZING STORAGE VOLUMES - A disk array redundancy controller ensures integrity of a mirrored or RAID storage array supporting a host system and minimizes recovery time responsive to a storage volume failure by traversing caches of recently written blocks to identify partially flushed stripes of data and recovering the inconsistent stripes on each of the storage volumes based on a master copy derived from the scan of all pre-failure caches of the storage array. The storage array employs nonvolatile caches in conjunction with solid state drive (SSD) storage volumes, allowing post-failure recovery of recently written blocks. A cache depth at least sufficient to store the largest stripe, or set of blocks, from the host ensures recovery of the entire stripe from a collective scan of the caches of all storage volumes of the storage array. | 03-27-2014 |
20140281062 | APPARATUS, SYSTEM AND METHOD FOR PROVIDING ACCESS TO A DEVICE FUNCTION - Techniques and mechanisms for providing access to a function with an input/output (I/O) device. In an embodiment, a main memory of a computer system including the I/O device stores a function-context data structure associating a function with a context for an access to the function. The I/O device stores a configuration for the I/O device to provide the function. In another embodiment, the software process exchanges information with the function-context data structure for the access to the function. The I/O device performs a synchronization of the function-context data structure and the configuration data structure with respect to one another, wherein the function-context data structure operates as a register level interface which interfaces the I/O device and the software process with one another. | 09-18-2014 |
