    摘要: An embodiment of the present invention is a technique to provide cache support for direct memory access address translation. A cache structure stores cached entries used in address translation of a guest physical address to a host physical address. The guest physical address corresponds to a guest domain identified by a guest domain identifier in an input/output (I/O) transaction requested by an I/O device. A register stores an invalidating domain identifier identifying an invalidating domain and an indicator indicating invalidating an entry in the cached entries having a tag.

    摘要: A system management request for a system management function is received from a virtual machine. A successful status is returned to the virtual machine in response to the system management request. A system management function is performed in response to the system management request and an aggregation of other system management requests directed to the system management function made by other virtual machines.

    摘要: Provided are a method, system, and article of manufacture, wherein in one embodiment of the method metadata related to a packet may be allocated in a host memory by a protocol processor, wherein the host memory may be comprised in a host that may be capable of being coupled to a network adapter. The metadata may be copied from the host memory to an adapter memory that may be associated with the network adapter. The copied metadata may be processed by the protocol processor.

    摘要: Provided are a method, system, and article of manufacture, wherein in one implementation of the method a memory buffer is allocated in a host memory by a protocol processor, wherein the host memory is comprised in a host that is coupled to a network adapter. A packet is processed initially at the network adapter to generate data for offloading to the memory buffer in the host. The generated data is offloaded by the protocol processor to the memory buffer in the host. The offloaded data is processed by the protocol processor.
