Will s3 board support FreeRTOS SMP?

[lanistor]

When open SMP (esp-idf 5.1), the code throw some error. And does epdiy parallel rendering mode support SMP?

Hello @lanistor what is SMP can you add a link or something?

Here is th link: https://docs.espressif.com/projects/esp-idf/en/v5.2-rc1/esp32s2/api-reference/system/freertos_idf.html .

Symmetric multiprocessing is a computing architecture where two or more identical CPU cores are connected to a single shared main memory and controlled by a single operating system. In general, an SMP system:

has multiple cores running independently. Each core has its own register file, interrupts, and interrupt handling.

presents an identical view of memory to each core. Thus, a piece of code that accesses a particular memory address has the same effect regardless of which core it runs on.

The main advantages of an SMP system compared to single-core or asymmetric multiprocessing systems are that:

the presence of multiple cores allows for multiple hardware threads, thus increasing overall processing throughput.

having symmetric memory means that threads can switch cores during execution. This, in general, can lead to better CPU utilization.
