Configure the IPC tasks stack size. One 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 stack size should be enough for most common use cases.
|
|
It can be shrunk if you are sure that you do not use any custom
|
|
IPC functionality.

If this option is not enabled then the IPC task will keep behavior
|
|
same as prior to that of ESP-IDF v4.0, and hence IPC task will run
|
|
at (configMAX_PRIORITIES - 1) priority.

This feature servers a similar purpose to the IPC except that the callback function is run
|
|
in the context of a level 4 interrupt (i.e., high priority/level interrupt). The IPC ISR
|
|
feature is intended for low latency execution of simple functions written in assembly on
|
|
another CPU. Due to being run in higher level interrupt context, the assembly functions
|
|
should be written in a particular way (see esp_test_ipc_isr_asm() and the "High-Level Interrupts"
|
|
chapter in hlinterrupts.rst for more details).
