Hi All,
I'm trying to use xenomai on linux 5.4. I previously used xenomai 3.0 on
linux 4.9 and xenomai 3.1 on linux 4.19 and both were fine. However when I
use xenomai 3.2.1 on linux 5.4 there are errors in compile. One of the
errors says
expected expression before ')' token (__flags) = hard_preempt_disable();
for the macro below in fpsimd.c:
#define get_cpu_fpsimd_context(__flags) \ do { \ (__flags) =
hard_preempt_disable(); \ __get_cpu_fpsimd_context(); \ } while (0)
hard_preempt_disable is also a macro defined in preempt.h:
#define hard_preempt_disable() \ ({ \ unsigned long __flags__; \ __flags__
= hard_local_irq_save(); \ if (__ipipe_root_p) \ preempt_disable(); \
__flags__; \ })
It is clear that hard_preempt_disable() should be a function-like macro but
is actually not. It seems to me that there are inconsistencies in the ipipe
patch I used. I used ipipe-core-5.4.72-arm64-0.patch. Anyone has a
suggestion on I can I resolve this issue?
Best Regards,
Yunjie
