/**
|
|
* @brief Execute a callback on a given CPU without any blocking operations for the caller
|
|
*
|
|
* Since it does not have any blocking operations it is suitable to be run from interrupts
|
|
* or even when the Scheduler on the current core is suspended.
|
|
*
|
|
* The function:
|
|
* - does not wait for the callback to begin or complete execution,
|
|
* - does not change the IPC priority.
|
|
* The function returns after sending a notification to the IPC task to execute the callback.
|
|
*
|
|
* @param[in] cpu_id CPU where the given function should be executed (0 or 1)
|
|
* @param[in] func Pointer to a function of type void func(void* arg) to be executed
|
|
* @param[in] arg Arbitrary argument of type void* to be passed into the function
|
|
*
|
|
* @return
|
|
* - ESP_ERR_INVALID_ARG if cpu_id is invalid
|
|
* - ESP_ERR_INVALID_STATE 1. IPC tasks have not been initialized yet,
|
|
* 2. cpu_id requests IPC on the current core, but the FreeRTOS scheduler is not running on it
|
|
* (the IPC task cannot be executed).
|
|
* - ESP_FAIL IPC is busy due to a previous call was not completed.
|
|
* - ESP_OK otherwise
