- efi_lookup_devpath() uses the DEVICE_PATH_PROTOCOL to obtain the DEVICE_PATH for a given EFI handle. - efi_lookup_image_devpath() uses the LOADED_IMAGE_DEVICE_PATH_PROTOCOL to lookup the device path of the device used to load a loaded image. - efi_devpath_name() uses the DEVICE_PATH_TO_TEXT_PROTOCOL to generate a string description of a device path. The returned string is a CHAR16 string that can be printed via the recently added '%S' format in libstand's printf(). Note that the returned string is returned in allocated storage that should be freed by calling efi_free_devpath_name(). - efi_devpath_last_node() walks a DEVICE_PATH returning a pointer to the final node in the path (not counting the terminating node). That is, it returns a pointer to the last meaninful node in a DEVICE_PATH. - efi_devpath_trim() generates a new DEVICE_PATH from an existing DEVICE_PATH. The new DEVICE_PATH does not include the last non-terminating node in the original path. If the original DEVICE_PATH only contains the terminating node, this function returns NULL. The caller is responsible for freeing the returned DEVICE_PATH via free(). - efi_devpath_handle() attempts to find a handle that corresponds to a given device path. However, if nodes at the end of the device path do not have valid handles associated with them, this function will return a handle that matches a node earlier in the device path. In particular, this function returns a handle for the node closest to the end of the device path which has a valid handle. Sponsored by: Cisco Systems |
