Sergio Rodriguez 2e2ad8166e qemu: Creation of QEMU specific platforms Setting up new platforms to handle emulation, and make them the only ones able to run on QEMU from the Makefile "qemu" target to avoid confusion with other platforms. We have now platform qemu_x86 and platform qemu_cortex_m3, also modification to the sanity checks to have qemu support only on those platforms Signed-off-by: Sergio Rodriguez <sergio.sf.rodriguez@intel.com> Change-Id: I9291918a1d58fea4f37750ada78234628f9a5d98 Signed-off-by: Anas Nashif <anas.nashif@intel.com>		2016-02-05 20:24:56 -05:00

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
