Yes,
if you #define RTEMS_SMP you can use the MrsP protocol (for example) by
calling
rtems_semaphore_create with an attribute set containing
RTEMS_PRIORITY | RTEMS_BINARY_SEMAPHORE |
RTEMS_MULTIPROCESSOR_RESOURCE_SHARING.
You can then use rtems_semaphore_obtain, rtems_semaphore_release
, rtems_semaphore_delete and others in the usual way.

Can the rtems_semaphore_*() routines be used on SMP systems?
