| 20100153974 | OBTAIN BUFFERS FOR AN INPUT/OUTPUT DRIVER - Disclosed is a computer implemented method, computer program product, and apparatus to obtain buffers in a multiprocessor system. A software component receives a call from an I/O device driver for a buffer, the call including at least one parameter, and walks a bucket data structure to a current bucket. The software component then determines whether the current bucket is free, and obtains a buffer list contained with the current bucket. Responsive to a determination that the current bucket is free, the software component determines whether sufficient buffers are obtained based on the parameter. Upon determining there are sufficient buffers obtained, the software component provides the current bucket and a second bucket as a single buffer list to the I/O device driver. | 06-17-2010 |
| 20100223419 | COPY CIRCUMVENTION IN A VIRTUAL NETWORK ENVIRONMENT - A method, system, and computer program product for circumventing data copy operations in a virtual network environment. The method includes copying a data packet from a user space to a first kernel space of a first logical partition (LPAR). Using a hypervisor, a mapped address of a receiving virtual Ethernet driver in a second LPAR is requested. The first mapped address is associated with a buffer of the receiving virtual Ethernet driver. The data packet is copied directly from the first kernel space of the first LPAR to a destination in a second kernel space of the second LPAR. The destination is determined utilizing the mapped address. The direct copying to the destination bypasses (i) a data packet copy operation from the first kernel space to a transmitting virtual Ethernet driver of the first LPAR, and (ii) a data packet copy operation via the hypervisor. The receiving virtual Ethernet driver is notified that the data packet has been successfully copied to the destination in the second LPAR. | 09-02-2010 |
| 20100251268 | SERIALIZED ACCESS TO AN I/O ADAPTER THROUGH ATOMIC OPERATION - Disclosed is a computer implemented method, computer program product, and apparatus to enqueue one or more packets in a device driver for an I/O adapter. A device driver receives, by a processor executing the device driver, a reference to a list of transmit packets. The device driver may then atomically fetch and set a transmit active flag, wherein atomically setting comprises determining a former status of the transmit active flag. Responsive to a determination that a former status of the transmit active flag is different than a current status of the transmit active flag, the device driver atomically removes, by a processor executing the device driver, any packets referenced by a host machine transmit queue reference. The device driver pre-pends transmit packets referenced by the host machine transmit queue reference to the list of transmit packets to form an augmented list of transmit packets. The device driver builds a work request based on the augmented list of transmit packets. The device driver notifies the I/O adapter of the work request. The device driver atomically resets the transmit active flag. | 09-30-2010 |
| 20100296518 | Single DMA Transfers from Device Drivers to Network Adapters - Methods and arrangements of data communications are discussed. Embodiments include transformations, code, state machines or other logic to provide data communications. An embodiment may involve receiving from a protocol stack a request for a buffer to hold data. The data may consist of all or part of a payload of a packet. The embodiment may also involve allocating space in a buffer for the data and for a header of a packet. The protocol stack may store the data in a portion of the buffer and hand down the buffer to a network device driver. The embodiment may also involve the network device driver transferring the entire packet from the buffer to a communications adapter in a single direct memory access (DMA) operation. | 11-25-2010 |
| 20110096659 | Zero Packet Loss Energy Efficient Ethernet Link Transition Via Driver Fast Failover - A mechanism for zero packet loss with energy efficient Ethernet link transition via driver fast failover is provided. By default, the mechanism uses a primary adapter running at low speed with low energy usage and a secondary adapter that is disabled. This default configuration is used during periods of low link utilization. When system or input/output load is such that high speed is required, then the mechanism enables the secondary adapter to its highest supported link speed. All transmit traffic in progress running over the primary adapter will complete, and upon completion, the driver generates an address resolution request and sends the request over the secondary adapter. After this process completes, the primary adapter transitions to link down and zero packet loss transition completes. | 04-28-2011 |

| 20110227673 | GROUND STRUCTURES IN RESONATORS FOR PLANAR AND FOLDED DISTRIBUTED ELECTROMAGNETIC WAVE FILTERS - Coupling between non-adjacent resonators and wave propagation through the waveguide structure in distributed EM filters are reduced by forming one or more holes in one or more of the resonators (planar or folded) and by passing a conductive structure through each hole normal to the resonator. The conductive structures (vertical vias or horizontal strips) are preferably grounded, either by direct connection or capacitive coupling to one or more ground planes or by creation of a virtual ground. The holes are spaced apart from the edges of the resonator so as to minimize any interference with the current and fields concentrated at the edges of each resonator. These conductive structures narrow the effective cavity width “a | 09-22-2011 |
