APIs Exported by NuttX to Architecture-Specific Logic
|

|
|
=====================================================
|
||
|
|
|
||
|
|
These are standard interfaces that are exported by the OS for use
|
||
|
|
by the architecture specific logic.

.. c:function:: void nx_start(void)

|
|
|

|
|
.. c:function:: void nxsched_process_timer(void)
|
||
|
|
|
||
|
|
This function handles system timer events. The
|
||
|
|
timer interrupt logic itself is implemented in the architecture
|
||
|
|
specific code, but must call the following OS function
|
||
|
|
periodically -- the calling interval must be
|
||
|
|
``CONFIG_USEC_PER_TICK``.
|
||
|
|
|
||
|
|
.. c:function:: void nxsched_timer_expiration(void)
|
||
|
|
|
||
|
|
Description: if ``CONFIG_SCHED_TICKLESS`` is defined, then this
|
||
|
|
function is provided by the RTOS base code and called from
|
||
|
|
platform-specific code when the interval timer used to implemented
|
||
|
|
the tick-less OS expires.
|
||
|
|
|
||
|
|
**Assumptions**: Base code implementation assumes that this
|
||
|
|
function is called from interrupt handling logic with interrupts disabled.
|
||
|
|
|
||
|
|
.. c:function:: void nxsched_alarm_expiration(void);
|
||
|
|
|
||
|
|
If ``CONFIG_SCHED_TICKLESS`` is defined, then this
|
||
|
|
function is provided by the RTOS base code and called from
|
||
|
|
platform-specific code when the interval timer used to implemented
|
||
|
|
the tick-less OS expires.
|
||
|
|
|

|
**Assumptions**: Base code implementation assumes that this
|
||
|
|
function is called from interrupt handling logic with interrupts disabled.
|
||
|
|
|
||
|
|
.. c:function:: void irq_dispatch(int irq, FAR void *context)
|
||
|
|
|
||
|
|
This function must be called from the
|
||
|
|
architecture- specific logic in order to display an interrupt to
|
||
|
|
the appropriate, registered handling logic.
