A Multiprocessor CPU Performance Monitor will be shipped with this product. This tool will display CPU utilization for each processor in bar graph and histogram modes. It will be written as a PM application and will display each processor's bar or line as a different color. This tool will also have the capability of placing each processor offline or online. This is useful to show the scalability of OS/2 for SMP V2.11. It may also be used for debug purposes. This tool will use the APIs described above. It is also desirable to be able to display the time spent waiting inside of the major spinlocks, such as the Ring 0 spinlock. It is also desirable to display the interrupt activity for each processor.
