  • Patent number: 9916243
    Abstract: A method and apparatus for performing a bus lock and a translation lookaside buffer invalidate transaction includes receiving, by a lock master, a lock request from a first processor in a system. The lock master sends a quiesce request to all processors in the system, and upon receipt of the quiesce request from the lock master, all processors cease issuing any new transactions and issue a quiesce granted transaction. Upon receipt of the quiesce granted transactions from all processors, the lock master issues a lock granted message that includes an identifier of the first processor. The first processor performs an atomic transaction sequence and sends a first lock release message to the lock master upon completion of the atomic transaction sequence. The lock master sends a second lock release message to all processors upon receiving the first lock release message from the first processor.

  • Patent number: 9880779
    Abstract: A system and method for performing copy offload operations. When a copy offload operation from a first volume (pointing to a first medium) to a second volume (pointing to a second medium) is requested, the copy offload operation is performed without accessing the data being copied. A third medium is created, and the first medium is recorded as the underlying medium of the third medium. The first volume is re-pointed to the third medium. Also, a fourth medium is created, the second volume is re-pointed to the fourth medium, and the second medium is recorded as the underlying medium of the targeted range of the fourth medium. All other ranges of the fourth medium have the second medium as their underlying medium.

  • Patent number: 9870187
    Abstract: Described is a technology by which routing of data may be automatically modified based on detected state data of a computing system. For example, user input may be routed from an actuator set to a host computer system when the host computer system is in an online state, or to an auxiliary computing device when the host computer system is offline. State may be determined based on one or more various criteria, such as online or offline, laptop lid position, display orientation, current communication and/or other criteria. The auxiliary display and/or actuator set may be embedded in the host computer system, or each may be separable from it or standalone, such as a remote control or cellular phone.

  • Patent number: 9836418
    Abstract: A method of scheduling and controlling asynchronous tasks to provide deterministic behavior in time-partitioned operating systems, such as an ARINC 653 partitioned operating environment. The asynchronous tasks are allocated CPU time in a deterministic but dynamically decreasing manner. In one embodiment, the asynchronous tasks may occur in any order within a major time frame (that is, their sequencing is not statically deterministic); however, the dynamic time allotment prevents any task from overrunning its allotment and prevents any task from interfering with other tasks (whether synchronous or asynchronous).

  • Patent number: 9832267
    Abstract: Described is a technology by which an owner node in a server cluster maintains ownership of a storage mechanism through a persistent reservation mechanism, while allowing non-owning nodes read and write access to the storage mechanism. An owner node writes a reservation key to a registration table associated with the storage mechanism. Non-owning nodes write a shared key that gives them read and write access. The owner node validates the shared keys against cluster membership data, and preempts (e.g., removes) any key deemed not valid. The owner node also defends ownership against challenges to ownership made by other nodes, so that another node can take over ownership if a (formerly) owning node is unable to defend, e.g., because of a failure.

  • Patent number: 9798684
    Abstract: Methods and systems are described for reading from or writing to a plurality of slave devices connected to a communications bus having a common data line. The slave devices are mapped to a virtual device address and the communication is initiated by the master by signaling a start condition and the virtual device address. Each of the slave devices mapped to the virtual device address identifies a register in that slave device associated with the virtual device address and, in sequence, performs a read or write operation on the bus with regard to its identified register in a respective predetermined time slot within the communication or to a corresponding virtual register address assigned to the slave device previously.

  • Patent number: 9785590
    Abstract: The invention pertains to automatically addressing devices on a network. The controller tests each address from a list of available addresses. If the control device receives a response the corresponding address is eliminated from the list of available addresses. The control device sends an arming signal which is received by all participating devices. The devices prepare for a triggering signal. When the trigger signal is received each device waits a random amount of time. During this time each device looks for communication on the bus, if communication is detected the device quits timing and remains unaddressed, if not it sends a signal to the control device to accept the address.
