NAME
       rtas - Allows userspace to call RTAS (Run Time Abstraction Services)

SYNOPSIS
       int ppc_rtas (struct rtas_args *uargs);

DESCRIPTION
       ppc_rtas  enables userspace manipulation of the RunTime Abstraction Services (RTAS). RTAS provides for a portable method of access and set-
       ting system information. For example, you could gather information on various system sensors and set poweron values. RTAS is  accessed  via
       the  /proc  entry called "rtas". Manipulations on RTAS are implemented via command line arguments on /proc/rtas.  The values for uargs vary
       greatly.  For more information, see the view/arch/ppcKconfig file.

RETURN VALUE
       rtas returns 0 on success; otherwise it returns one of the errors listed in the "Errors" section.

ERRORS
       -EPERM User does not have CAP_SYS_ADMIN capabilities.

       -EFAULT
	      Problem copying uargs values to/from user space.

       -EINVAL
	      Either number of uargs passed in too large or size of uargs array too large.
