摘要： A method and apparatus for controlling state information retention determines at least a state information save or restore condition for at least one processing circuit such as one or more CPU or GPU cores or pipelines, in an integrated circuit. In response to determining the state information save or restore condition, the method and apparatus controls either or both of saving or restoring of state information for different virtual machines operating on the processing circuit, into corresponding on-die persistent passive variable resistance memory. The state information save or restore condition is a virtual machine level state information save or restore condition. State information for each of differing virtual machines is saved or restored from differing on-die passive variable resistance memory cells that are assigned on a per-virtual machine basis.

摘要： The invention utilizes a separate queue per output port as implemented in the traditional simple queuing schemes of the prior art. Further, it also uses the information found in the packet header to determine the output port and the next output port. Based on this information, it utilizes queues dedicated to congested flows, or “Congested Flow” queues. When the switch determines that, based on the first output port and the second subsequent output port, a packet in the output queue is destined for a congested path, it sets the offending packet aside in a Congested Flow queue, thereby allowing other packets destined for the first output port to continue to be transmitted. In this way, the HOL blocking issue is addressed, without the need for a significantly increased number of output queues.

摘要： The invention provides a system and method for identifying and communicating congested paths throughout a network fabric. Briefly, the present invention augments the congestion management mechanism defined in ASI to allow for the communication of congested paths through the fabric, rather than the simple congested output port notification supported today through the use of DLLPs. Further, it also uses the communication mechanisms already defined in the ASI specification to implement this additional capability. Specifically, the present invention uses Transaction Layer Packets (TLPs) to communicate the information concerning congested flows throughout the network. This packet type allows the inclusion of much more information than DLLPs, allowing a more comprehensive and elegant solution to the issue of congestion management in an Advanced Switching network fabric.

摘要： A system and method for transferring data between two relatively autonomous processors using a sockets interface. In particular, a source SDT (“socket data transfer”) engine tells a destination SDT engine that data is available. Next the destination SDT engine then sends a data request to the source SDT engine. The source SDT engine then sends data to the destination SDT engine.

摘要： The invention provides an improved architecture for credit based flow control. Briefly, the memory space within the receiving switch is separated into two parts, a statically allocated portion and a dynamically allocated portion. Packets are first placed in the dynamically allocated portion, and the credits are returned immediately. When the dynamically allocated portion has no additional space, the packets are then stored in the memory portion statically allocated to the specific virtual circuit. Credits are returned when the packets are removed from the statically allocated memory portion. This scenario allows the immediate return of credits when there is space available in the dynamically allocated memory portion. It also allows improved sharing of the overall memory since more of the overall memory can be made available to a particular virtual circuit.
摘要翻译：本发明提供了一种用于基于信用的流量控制的改进的架构。简而言之，接收交换机内的存储器空间分为静态分配部分和动态分配部分两部分。数据包首先被放置在动态分配的部分中，并且立即返回信用。当动态分配的部分没有额外的空间时，分组然后被存储在静态分配给特定虚拟电路的存储器部分中。当数据包从静态分配的内存部分中删除时，将返回积分。这种情况允许在动态分配的存储器部分中存在可用空间时立即返回信用。它还允许改进的总体存储器的共享，因为整个存储器的更多可以被提供给特定的虚拟电路。

摘要： A method for accessing a configuration space of a device is described. The method includes setting a first field of a packet to a value to specify a destination device, and setting a second field of the packet to a defined value to indicate that the packet is a configuration access packet. The method further includes setting a third field of the configuration access packet to a value to select one of a plurality of configuration apertures of a configuration space of the destination device, and setting a fourth field of the configuration access packet to a value to address a specific memory location within the selected aperture.
