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: 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 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
|
|
|
|
