FreeRTOS SMP

[derricksenva]

The documentation for v5.0 seems to imply that the modified FreeRTOS component included with ESP-IDF is designed with SMP built in by default: docs.espressif.com/projects/esp-idf/en/ ... eertos-smp.

But, menuconfig seems to imply that this is optional. In the image below, there is an option to enable SMP that is not enabled by default and also says FEATURE UNDER DEVELOPMENT. Can someone clarify what is correct? Does FreeRTOS run in AMP mode by default, or does the option in menuconfig enable "Vanilla" FreeRTOS SMP instead of the modified ESP-IDF version of FreeRTOS SMP?

That setting enables Amazon SMP FreeRTOS, an SMP version of FreeRTOS written by Amazon themselves (see docs). If disabled, then IDF FreeRTOS is run instead, this is a modified version of FreeRTOS written by us that also supports SMP.
