Anas Nashif f62d86c42b samples: get rid of obsolete usage of ARCH variable Using ARCH variable to select different configurations for the different architectures is misleading and conflicts with the variable ARCH being used by the build system. The variable is not needed, it is application specific and an application can be built without the need to specify ARCH on the command line. This is yet another item specific to samples and test cases that wrongfully being used and documented for every application. We need to use another variable and just make it clear it is specific to samples and how they are written. One possible solution is to have a script that gets the architecture based on the board being used.

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


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.
