[Xen-devel] about map_pages_to_xen call during boot memory allocator initialization
Hi All, I know that during the initialization of boot memory allocator , memory is mapped into Xen''s pagetable and I know this is a 1:1 mapping under x86_32 which means the physical address equals the linear address . So what purpose is this mapping? After all , boot allocator just return page frame number , not the physical address the caller must do another mapping , for example , in init_frametable . Thank you very much yushang _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
