Title: Context and IRQ APIs
Description:
This test verifies that the kernel CPU and context APIs operate as expected.
APIs tested in this test set
============================
k_thread_spawn
- start a helper fiber to help with k_yield() tests
- start a fiber to test fiber related functionality
k_yield
- Called by a higher priority fiber when there is another fiber
- Called by an equal priority fiber when there is another fiber
- Called by a lower priority fiber when there is another fiber
k_current_get
- Called from an ISR (interrupted a task)
- Called from an ISR (interrupted a fiber)
- Called from a task
- Called from a fiber
k_is_in_isr
- Called from an ISR that interrupted a task
- Called from an ISR that interrupted a fiber
- Called from a task
- Called from a fiber
k_cpu_idle
- CPU to be woken up by tick timer. Thus, after each call, the tick count
should have advanced by one tick.
irq_lock
- 1. Count the number of calls to _tick_get_32() before a tick expires.
- 2. Once determined, call _tick_get_32() many more times than that
with interrupts locked. Check that the tick count remains unchanged.
irq_unlock
- Continuation irq_lock: unlock interrupts, loop and verify the tick
count changes.
irq_offload
- Used when triggering an ISR to perform ISR context work.
irq_enable
irq_disable
- Use these routines to disable and enable timer interrupts so that they can
be tested in the same way as irq_lock() and irq_unlock().
---------------------------------------------------------------------------
Building and Running Project:
This 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
