Abstract
A method and system within a data processing system or information handling system are disclosed for counting various events from a running program (hereafter called a process) by taking a trace by way of using an interruption. According to the present invention, a performance monitor feature within a data processing system is programmed to generate a trace interrupt after each branch instruction, or at the end of each basic block of code from a currently running program or process. By programming monitor mode control registers within the performance monitor feature, one or more counters are programmed to count various events happening on the data processing system thereby creating tracing information. If the current process is a process to be traced, the tracing information is stored in a trace buffer for post-processing analysis, the counters are reset to zero returning back to the process from the interrupt.
