Title: Microkernel Object Performance Description: AppKernel is used to measure the performance of microkernel events, mutexes, semaphores, FIFOs, mailboxes, pipes, memory maps, and memory pools. -------------------------------------------------------------------------------- Building and Running Project: This project outputs to the console. It can be built and executed on QEMU as follows: make run -------------------------------------------------------------------------------- Troubleshooting: Problems caused by out-dated project information can be addressed by issuing one of the following commands then rebuilding the project: make clean # discard results of previous builds # but keep existing configuration info or make pristine # discard results of previous builds # and restore pre-defined configuration info -------------------------------------------------------------------------------- Sample Output:
