Looking for samples for multicore SMP

[hcye2022]

From the docs it appears that multicore SMP has been tested on esp32 and qemu_x86. But I search the codebase and did not find any sample using the SMP API (e.g. k_thread_cpu_mask_xxx). Can someone point me to such code, if they exist?

A grep shows some relevant tests :

• tests/arch/common/timing
• tests/boards/intel_adsp/smoke

See tests in tests/kernel/smp* there are way more relevant code (using k_thread_cpu_pin for instance)

Thanks for the info. Unfortunately that is for unit test only, not executable on a real board. And it has only k_thread_cpu_pin(), so it is AMP not SMP.

While it is true that SMP has been tested in ESP32, it is also true that it is not working properly. PTAL: #56011
