Filed: 2016-08-05
Abstract: The use of control parameters in an electronic device are monitored. The parameters may relate to memory or cache management, inter-process communication or remote or local procedure calls. A graph of context switch patterns is also created and patterns of parameter use are associated with paths in the graph. When a context switch occurs, the device identifies the path of context changes to reach the new context and any associated pattern of control parameter use. It then sets control parameters based on the pattern. The pattern may determine which parameters are set and their order. A hash of the pattern may be stored in the device to identify it. The patterns may be generated on a server and transferred to the device. An unrecognized pattern may generate an alert. Context specific data may be added to the patterns.
