PowerPC FW introduced HVPIPE RTAS calls such as ibm,send-hvpipe-msg and ibm,receive-hvpipe-msg for the user space to exchange information with different sources such as Hardware Management Consoles (HMC). HVPIPE_IOC_CREATE_HANDLE is defined to use /dev/papr-hvpipe interface for ibm,send-hvpipe-msg and ibm,receive-hvpipe-msg RTAS calls. Also defined papr_hvpipe_hdr which will added in the payload that is passed between the kernel and the user space.
