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

--------------------------------------------------------------------------------
