Abstract:
1. A method, in data processing system having a control plane processor and one or more data plane processors, comprising: processing, in a data plane processor of the data processing system, an instruction requiring external assistance by an operating system library function or operating system service provided by an operating system running on the control plane processor, wherein the operating system runs solely in the control plane processor and the data plane processor accesses the operating system library function or operating system service via assistance from the control plane processor; generating, in the data plane processor, an assisted call message for requesting assistance from the control plane processor; signaling the control plane processor to process the assisted call message; and receiving, in the data plane processor, one or more return values from the control plane processor, wherein the one or more return values are generated based on the control plane processor executing the operating system library function or operating system service based on the assisted call message.
