Abstract
A system and method for tracing device drivers using a computer is described. A memory is interconnected with a processor in the computer and configured into a user memory space and a kernel memory space. An application process executes on the processor within the user memory space. An operating system kernel executes on the processor within the kernel memory space with a traced device driver. A tracing device driver executes on the processor within the kernel memory space and is interposed between the application process and the traced device driver to trace interactions occurring between the traced device driver and the application process and the kernel operating system. A tracing process executes on the processor within the user memory space and interfaces with the tracing device driver. The tracing process controls the tracing device driver in accordance with user-specified parameters and includes a display for result sets generated by the tracing device driver.
