Abstract
An embodiment may include circuitry that may write a message from a system memory in a host to a memory space in an input/output (I/O) controller in the host. A host operating system may reside, at least in part, in the system memory. The message may include both data and at least one descriptor associated with the data. The data may be included in the at least one descriptor. The circuitry also may signal the I/O controller that the writing has occurred.
