This will replace the current goal of 'make qemu' with 'make run' and moves Qemu handling into its own file and into the boards instead of being architecture specific. We should be able to add new boards that support some other type of emulation (by adding scripts/Makefile.<emu type>) and allow the board to define their own options for the use type of emulation. 'make qemu' will still work, however it will be deprecated, starting with this commit it is recommended to use 'make run'.

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 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
|
|
|
|
|
|
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.
