#include <sys/platform/ppc.h> void __ppc_yield(void); void __ppc_mdoio(void); void __ppc_mdoom(void);
__ppc_yield() provides a hint that performance will probably be improved if shared resources dedicated to the executing processor are released for use by other processors.
__ppc_mdoio() provides a hint that performance will probably be improved if shared resources dedicated to the executing processor are released until all outstanding storage accesses to caching-inhibited storage have been completed.
__ppc_mdoom() provides a hint that performance will probably be improved if shared resources dedicated to the executing processor are released until all outstanding storage accesses to cacheable storage for which the data is not in the cache have been completed.
