Abstract
An aspect of the present invention proposes a solution for correctly intercepting, capturing, and replaying tasks (such as functions and methods) in an interception layer operating between an application programming interface (API) and the driver of a processor by using synchronization objects such as fences. According to one or more embodiments of the present invention, the application will use what appears to the application to be a single synchronization object to signal (from a processor) and to wait (on a processor), but will actually be two separate synchronization objects in the interception layer. According to one or more embodiments, the solution proposed herein may be implemented as part of an module or tool that works as an interception layer between an application and an API exposed by a device driver of a resource, and allows for an efficient and effective approach to frame-debugging and live capture and replay of function bundles.
