Abstract: In an embodiment, a network adapter has a physical port that is multiplexed to multiple logical ports, which have default queues. The adapter also has other queues, which can be allocated to any logical port, and resources, which map tuples to queues. The tuples are derived from data in packets received via the physical port. The adapter determines which queue should receive a packet based on the received tuple and the resources. If the received tuple matches a resource, then the adapter stores the packet to the corresponding queue; otherwise, the adapter stores the packet to the default queue for the logical port specified by the packet. In response to receiving an allocation request from a requesting partition, if no resources are idle, a resource is selected for preemption that is already allocated to a selected partition. The selected resource is then allocated to the requesting partition.
Abstract translation: 在一个实施例中，网络适配器具有被复用到具有默认队列的多个逻辑端口的物理端口。 适配器还具有可以分配给任何逻辑端口的其他队列，以及将元组映射到队列的资源。 元组是通过物理端口接收的数据包中的数据导出的。 适配器根据接收的元组和资源确定哪个队列应该接收数据包。 如果接收到的元组与资源匹配，则适配器将数据包存储到相应的队列中; 否则，适配器将数据包存储到由数据包指定的逻辑端口的默认队列。 响应于从请求分区接收分配请求，如果没有资源空闲，则选择已经分配给所选分区的抢占资源。 然后将所选择的资源分配给请求分区。

Abstract: By switching a character generator between two different dot patterns or fonts for each character in response to the state of a normal/reverse mode control the legibility of reverse-video fonts is increased. In the reverse font (32), each vertical stroke has two (or more) consecutive dots in the vertical strokes wherever the normal font (31) has a single dot.

Abstract: A method and system for transmitting and receiving data from a host computer system to an Ethernet adapter are provided. The method comprises establishin g a connection between the host system and the Ethernet adapter pushing a transmit or receive request message from a host system device driver to the Ethernet adapter's request queue. Access to host memory is transferred to th e Ethernet adapter. If data is being transmitted to the Ethernet adapter, the adapter reads the data from a location in host memory specified in the transmit request message, and then transmits the data onto transmission medi a (e.g. wire, fiber). If the request message is a receive request, the adapter reads the data from the media and then sends the data into host memory at th e location specified in the receive request message. When the data transfer is complete, the adapter sends a response message back to the host. The respons e message includes a transaction ID which is used by the host device driver to associate the response message to the original request message.

Abstract: In an alphanumeric CRT display having normal/reverse video attribute, two timing circuits (1652, 1653) responsive to the raw video signal produce a modified video signal having two different dot durations and a switching circuit (1654) responsive to an attribute signal selectively enables one output of the two timing circuits (1652, 1653). In reverse mode, the character dots are made wider than in normal mode, to equalize the apparent width of the dots in the two modes.
