-.SH NAME
-__ppc_yield, __ppc_mdoio, __ppc_mdoom \-
-Hint the processor to release shared resources
-.SH LIBRARY
-Standard C library
-.RI ( libc ", " \-lc )
-.SH SYNOPSIS
-.nf
-.B #include <sys/platform/ppc.h>
-.P
-.B void __ppc_yield(void);
-.B void __ppc_mdoio(void);
-.B void __ppc_mdoom(void);
-.fi
-.SH 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.
-.P
-.BR __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.
-.P
-.BR __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.
-.P
-.BR __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.
