> Isn't up_cpu_index the _logical_ core number (which is only meaningful to the NuttX kernel), not the physical core number? I presume for AMP communication you need the physical core. Yes, that's why we have two api now: this_cpu and up_cpu_index. this_cpu is logical core number, up_cpu_index is physical core number. up_cpu_index always return the real core number regardless CONFIG_SMP setting on the other hand, this_cpu always return 0 if CONFIG_SMP is false after this patch: https://github.com/apache/nuttx/pull/13211 -- This is an automated message from the Apache Git Service.
