An IPC task runs on each core (in dual core mode), and allows for cross-core function calls. See IPC documentation for more details. The default IPC stack size should be enough for most common simple use cases. However, users can increase/decrease the stack size to their needs. config ESP_IPC_USES_CALLERS_PRIORITY bool "IPC runs at caller's priority" default y depends on !FREERTOS_UNICORE help If this option is not enabled then the IPC task will keep behavior same as prior to that of ESP-IDF v4.0, hence IPC task will run at (configMAX_PRIORITIES - 1) priority. config ESP_IPC_ISR_ENABLE bool default y if !FREERTOS_UNICORE help The IPC ISR feature is similar to the IPC feature except that the callback function is executed in the context of a High Priority Interrupt. The IPC ISR feature is itended for low latency execution of simple callbacks written in assembly on another CPU. Due to being run in a High Priority Interrupt, the assembly callbacks must be written with particular restrictions (see "IPC" and "High-Level Interrupt" docs for more details). endmenu # "IPC (Inter-Processor Call)
