NAME

       __ppc_yield, __ppc_mdoio, __ppc_mdoom - Hint the processor to release shared resources

SYNOPSIS

       #include <sys/platform/ppc.h>

       void __ppc_yield(void);
       void __ppc_mdoio(void);
       void __ppc_mdoom(void);

DESCRIPTION

       These  functions  provide  hints about the usage of resources that are shared with other processors on the Power architecture.  They can be
       used, for example, if a program waiting on a lock intends to divert the shared resources to be used by other processors.

       __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.

VERSIONS

       These functions first appeared in glibc in version 2.18.
