Thanks for your quick review. I think this patch is superfluous. In which scenario do you think it is > necessary?
It is from this mail conversation: https://lists.rtems.org/pipermail/devel/2020-September/061845.html followed by https://lists.rtems.org/pipermail/devel/2020-September/061846.html. Strong APA uses the value of CONFIGURE_MAXIMUM_PROCESSORS in its declaration <https://github.com/richidubey/rtems/blob/d3d1e4bc8e616738bd5892c59f82b174c399fc0b/cpukit/include/rtems/scheduler.h#L260> at cpukit/include/rtems/scheduler.h. This addition would be necessary to support future SMP schedulers that need to know the number of CPUs in the system at the time of configuration. > > /* Ensure that _CONFIGURE_MAXIMUM_PROCESSORS > 1 only in SMP > configurations */ > #if defined(CONFIGURE_MAXIMUM_PROCESSORS) && defined(RTEMS_SMP) > #define _CONFIGURE_MAXIMUM_PROCESSORS CONFIGURE_MAXIMUM_PROCESSORS > #else > #define _CONFIGURE_MAXIMUM_PROCESSORS 1 > #endif I can see this in percpu.h. It's weird that make still gave an error!
