Abstract
Methods and systems for efficiently interpreting operating system service requests on the same register or vector of a processor or CPU where the operating system service requests are initiated from native and non-native applications are provided. More particularly, a switching layer can enable processing of the operating system service requests by routing control of a particular request to an appropriate kernel subsystem or module based on the type of operating system service being requested and the type of application initiating the request. Additionally, the performance impact of the switching layer for native applications is overcome by dynamically reprogramming the processor or CPU on every change of active process so that only foreign applications are subject to the processing requirements of the switching layer.
