Configure the IPC tasks stack size. 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.

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.

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).
