* @brief Run a function in interrupt context
|
|
*
|
|
* This function synchronously runs the provided function in interrupt
|
|
* context, passing in the supplied device. Useful for test code
|
|
* which needs to show that kernel objects work correctly in interrupt
|
|
* context.
|
|
*
|
|
* Additionally, when CONFIG_IRQ_OFFLOAD_NESTED is set by the
|
|
* architecture, this routine works to synchronously invoke a nested
|
|
* interrupt when called from an ISR context (i.e. when k_is_in_isr()
|
|
* is true). Note that not all platforms will have hardware support
|
|
* for this capability, and even on those some interrupts may be
|
|
* running at unpreemptible priorities.
|
|
*
|
|
* @param routine The function to run
|
|
* @param parameter Argument to pass to the function when it is run as an
|
|
* interrupt
