摘要： Methods and apparatus for scheduling and controlling power management activities are disclosed. An example method includes automatically scheduling a wake-up alarm for a computing device and transitioning the computing device from an active power state to a first low power state. The example method also includes, in response to occurrence of the automatically scheduled wake-up alarm, transitioning the computing device from the first low power state to the active power state and transitioning the computing device from the active power state to a second low power state, where the second low power state is a lower power state than the first low power state.

摘要： According to one general aspect, a method may include operating a computing device in a first power mode. The method may also include executing, by a processor of the computing device, at least one non-interactive task. The method may also include detecting, by a processor of the computing device, a request to place the computing device in a second power mode, wherein the second power mode consumes less system resources than the first power mode. The method may further include delaying the transition of the computing device to the second power mode until either the completion of the non-interactive task or an overriding triggering event.

摘要： A method includes operating a computing device in a first power mode and a first operating state. The first operating state includes first operating state information stored in a volatile memory. The method includes receiving a first request to change the power mode from the first power mode to a second power mode. In response to receiving the first request, a sub-portion of the first operating state information that includes less than all of the first operating state information is stored in a non-volatile memory. The method includes receiving a second request to change the power mode from the second power mode to the first power mode. In response to receiving the second request, the computing device is restored to the first power mode, and is placed in a second operating state, by re-creating a portion of the first operating state information.

摘要： One embodiment of the present invention sets forth a method for failing back network connections to a network interface card (NIC) within a computing device. The method includes the steps of monitoring a failed or unreliable NIC within the computing device, determining that the failed or unreliable NIC has recovered, determining that a functional NIC within the computing device is overloaded, selecting a first connection set communicating through the overloaded NIC, and transferring the first connection set to the recovered NIC. With this approach, intelligent decisions can be advantageously made regarding whether to fail back a network connection set to a recovered NIC based on the traffic loads on the overloaded NIC and the recovered NIC. Such an approach to balancing network traffic across the functional NICs within a computing device may substantially improve overall performance relative to prior art techniques.

摘要： A hash engine in a network device driver maintains data on the utilization and error rate for each network interface card (“NIC”) within a local computing device. From this data, the hash engine intelligently selects transmit NICs and receive NICs based on various networking parameters provided from a software driver program. Transmit packets sent from the operating system in a local computing device to a remote computing device are intercepted, modified and redirected to transmit NICs selected by the hash engine for transmission to remote computing devices. Similarly, address resolution protocol (“ARP”) response packets sent by the operating system in response to ARP request packets are intercepted, modified and redirected to receive NICs selected by the hash engine for transmission. By selecting receive NICs and transmit NICs in this fashion, the hash engine is able to intelligently load balance transmit and receive traffic in the local computing device, thereby improving overall network performance relative to prior art techniques.

摘要： Method and apparatus for packet processing by re-insertion into network interface circuitry. A method for handling a burst of packets sent to network interface circuitry includes checking for a connection table entry for received packets, and responsive to non-existence of the connection table entry for the received packets, sending the packets to network interface software for processing. The network interface software processing includes: building the connection table entry; processing the packets; and sending the packets as processed to the network interface circuitry. Additionally, a method for re-inserting a packet responsive to an active audit mode is described.
