Thanks,
I am assuming this is the code that allocates space:
#define RTEMS_SCHEDULER_EDF_SMP( name ) \
> static struct { \
> Scheduler_EDF_SMP_Context Base; \
> Scheduler_EDF_SMP_Ready_queue Ready[ CONFIGURE_MAXIMUM_PROCESSORS
> + 1 ]; \
> } SCHEDULER_EDF_SMP_CONTEXT_NAME( name )
How do we use or refer to this 'Base'? How do we link this 'Ready' to the
'Ready' inside the EDF_SMP_Context?
