> In the file xen/include/asm-x86/mm.h, a "page_info" structure is > defined. I am wondering when the PGT_type is set to be PGT_none and > when it is set to be PGT_writable_page? It is set to PGT_writable_page when any guest has a writable mapping of that page. If the page is read only then it has type PGT_none. Thanks for the reply. When the guest loads the executable object's or library's text section into its pagecache, will the page_info be PGT_none or PGT_writable_page? Where can I find those functions that set the value of PGT_type? Thanks a lot.
