|

|
|
:synopsis: functionality specific to Zephyr
|
||
|
|
|
||
|
|
The ``zephyr`` module contains functions and classes specific to the Zephyr port.
|
||
|
|
|
||
|
|
Functions
|
||
|
|
---------
|
||
|
|
|
||
|
|
.. function:: is_preempt_thread()
|
||
|
|
|
||
|
|
Returns true if the current thread is a preemptible thread.
|
||
|
|
|
||
|
|
Zephyr preemptible threads are those with non-negative priority values (low priority levels), which therefore,
|
||
|
|
can be supplanted as soon as a higher or equal priority thread becomes ready.
|
||
|
|
|
||
|
|
.. function:: current_tid()
|
||
|
|
|
||
|
|
Returns the thread id of the current thread, which is used to reference the thread.
|
||
|
|
|
||
|
|
.. function:: thread_analyze()
|
||
|
|
|
||
|
|
Runs the Zephyr debug thread analyzer on the current thread and prints stack size statistics in the format:
|
||
|
|
|
||
|
|
"``thread_name``-20s: STACK: unused ``available_stack_space`` usage ``stack_space_used``
|
||
|
|
/ ``stack_size`` (``percent_stack_space_used`` %); CPU: ``cpu_utilization`` %"
|
||
|
|
|
||
|
|
* *CPU utilization is only printed if runtime statistics are configured via the ``CONFIG_THREAD_RUNTIME_STATS`` kconfig*
|
||
|
|
|
||
|
|
This function can only be accessed if ``CONFIG_THREAD_ANALYZER`` is configured for the port in ``zephyr/prj.conf``.
|
||
|
|
For more infomation, see documentation for Zephyr `thread analyzer
|
||
|
|
<https://docs.zephyrproject.org/latest/guides/debug_tools/thread-analyzer.html#thread-analyzer>`_.
|
||
|
|
|
||
|
|
.. function:: shell_exec(cmd_in)
|
||
|
|
|
||
|
|
Executes the given command on an UART backend. This function can only be accessed if ``CONFIG_SHELL_BACKEND_SERIAL``
|
||
|
|
is configured for the port in ``zephyr/prj.conf``.
|
||
|
|
|
||
|
|
A list of possible commands can be found in the documentation for Zephyr `shell commands <https://docs.zephyrproject.org/latest/reference/shell/index.html?highlight=shell_execute_cmd#commands>`_.
