Abstract:
A computer-based method configures a hardware circuit to transfer a message to a message queue in an operating system. The hardware circuit is used to transfer a message to the message queue in the operating system without requiring use of either the operating system or a hypervisor associated with the operating system. The using the hardware circuit uses a logical identifier associated with the message to select an entry in a mapping table of the hardware circuit. A value in the entry in the mapping table is used to select an entry in an action table. The entry in the action table is used to determine a tail pointer for the message queue. The hardware circuit appends the message to a location indicted by the tail pointer without requiring cycles of a hypervisor associated with the strand.
