Hello All, Could someone please enlighten me on the difference between xc_map_foreign_range() and xc_map_foreign_batch() used in xc_save/restore. I know both of them function similar to mmap. I guess the xc_map_foreign_range directly maps the range of addresses from DomU to Dom0.
However I am not sure what xc_map_foreign_batch does. It always seems to be used for mapping page frame lists. Can someone please tell me what is does and why it is used. Thank you.
