The function is called by a set of tasks +per CPU during the test. The tasks are linked together by semaphores +in such a way that only one task is active at any given time. At the +end of the test the data stored in the capture trace is verified to +make sure that all invocations of the traced function were stored correctly. + +The test also traces clock tick interrupts. If an interrupt handler +with the name "Clock" or "clock" exists, it is assumed to be the main +clock interrupt handler. The test wraps this function with another function +that adds an entry to the trace for every clock tick. |
