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

Problems with QEMU on ARM:
Qemu v2.1 for ARM platform do not support tickless idle. If run the sample
project in QEMU with the CONFIG_TICKLESS_IDLE option enabled, the project
could present an erratic behaviour.
Add profile collector sample. Add a project that shows how to collect the data from the profiler. Change-Id: Ie9cc88290de594720739b30d4e872fe51d353f6e Signed-off-by: Yonattan Louise <yonattan.a.louise.mendoza@intel.com>
