    Yes ipcFramesOutHost does not allocate buffers. The application can allocate a physically contiguous buffer by some means (cmem/allocate from ShareRegion heap in SR0 via Vsys_allocBuf()) etc and pass the buffer to ipcFramesOutHost .Note that the physical address of the buffer should be populated by the application before sending it to ipcFrameOutHost.
