Title: Context and IRQ APIs
Description:
This test verifies that the nanokernel CPU and context APIs operate as expected.
---------------------------------------------------------------------------
Building and Running Project:
This nanokernel 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
---------------------------------------------------------------------------
