This said, the I-pipe patch suffers from a silly bug causing infinite recursion when CONFIG_SMP + CONFIG_PREEMPT + CONFIG_DEBUG_PREEMPT are all enabled. The patch below fixes it: --- a/include/asm-x86_64/ipipe.h +++ b/include/asm-x86_64/ipipe.h @@ -93,7 +93,7 @@ /* The logical processor id is read from the PDA, so this is always * safe, regardless of the underlying stack. */ -#define ipipe_processor_id() smp_processor_id() +#define ipipe_processor_id() raw_smp_processor_id() #else /* !CONFIG_SMP */ -- Philippe. _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
