Anas Nashif fdb1daf786 kconfig: add board configurations First step for adding the new board layer. Create configurations for the various boards we support on x86 under boards with the new Kconfig variables defining them. The board selection is optional, that means you will be able to run make menuconfig and create your own .config and select any SoC.

Title: Kernel Event Logger Sample

Description:

This sample uses the philosopher sample with two additional tasks to show the
profiling data on different system's states. The fork manager task controls the
fork's availibilty. The worker task performs intermitently heavy processing,
allowing or preventing the system to go idle.

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

Building and Running Project:

This microkernel project outputs to the console. It can be built and executed
on QEMU as follows:

    make qemu

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

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
