摘要： A computer system may comprise a second device operating as a producer that may steer data units to a first device operating as a consumer. A processing core of the first device may wake-up the second device after generating a first data unit. The second device may generate steering values after retrieving a first data unit directly from the cache of the first device. The second device may populate a flow table with a plurality of entries using the steering values. The second device may receive a packet over a network and store the packet directly into the cache of the first device using a first steering value. The second device may direct an interrupt signal to the processing core of the first device using a second steering value.

摘要： A virtual machine with a directly assigned network device and supported on a host may be migrated to other host without loss of network connectivity. Such migration is enabled by bonding a physical network interface driver (NIC) and a virtual NIC driver of the host. A virtual machine monitor of the host may determine whether the virtual machine is to be migrated to the other host. The virtual machine monitor may allow hot-plug removal of the network device. However, the virtual machine may still maintain network connectivity through the virtual NIC. The virtual machine may be migrated to the other host. After migration, the virtual machine may continue to maintain the network connectivity either through the virtual NIC driver or bond with a physical NIC driver of the network device coupled to the other host.

摘要： In an embodiment, a method is provided. The method of this embodiment provides determining a flow context associated with a receive packet; and if the flow context complies with a dynamic interrupt moderation policy having one or more rules, generating an interrupt to process the receive packet substantially independently of an interrupt generated in accordance with an interrupt coalescing scheme (“coalesced interrupt”). Other embodiments are disclosed and/or claimed.

摘要： A method and apparatus for performing network-based control functions on an alert-enabled managed client. An alert proxy translates generic, management-based command data received from a management application/agent into specific client-based hardware control data. The alert proxy transmits a data packet containing the hardware control data over a network to an alert-enabled managed client. Alert hardware within the alert-enabled managed client parses the hardware control data into control bits and utilizes the control bits to set or clear registers within the alert-enabled managed client so as to effectuate the specified control operations. The control operations may be performed on the alert-enabled managed client independent of the operational status of the alert-enabled managed client's operating system.

摘要翻译： 一种用于在启用警报的受管客户端上执行基于网络的控制功能的方法和装置。 警报代理将从管理应用/代理接收的基于管理的通用命令数据转换为特定的基于客户端的硬件控制数据。 警报代理通过网络将包含硬件控制数据的数据包发送到启用警报的受管客户端。 启用警报的受管客户端中的警报硬件将硬件控制数据解析为控制位，并利用控制位来设置或清除启用了警报的受管客户端内的寄存器，以实现指定的控制操作。 控制操作可以在启用了启用警报的受管客户端上独立于启用了警报的受管客户端的操作系统的操作状态执行。

摘要： In one embodiment, a data movement module (DMM) may receive a command to copy data from a source buffer to a destination buffer. One or more cache lines corresponding to addresses of the source buffer and the destination buffer may be invalidated. Also, an entry may be added to a queue to indicate that the command to copy is completion pending.
