Xeno Linux never pins L1 tables ?
...ping my own 32-bit (no PAE) paravirtualized kernel for xen with
Mini-OS as a starting point. I am currently working on process page table
support (equivalent of arch/i386/mm/pgtable-xen.c) and mostly following
Linux for the moment. I noticed that linux-2.6.18-xen never pins an L1 table
(a pte), yet __pgd_pin() walks the page directory and gives up write access
on the kernel mappings of pte pages and only pins the pgd page. How do
set_pte() and set_pte_at() macros work if they are writing directly to the
page table entires ? do we fault in the kernel to handle this ?!
thanks,
satya.
