odd gfn number checking in p2m.c
Hello,
how can a gfn become 0x555555 as checked in
p2m.c:guest_physmap_add_entry() and p2m_alloc_table()?
Looking further in p2m.c, audit_p2m() checks only for a 32bit value.
So where is that magic number set, and why is it not a define to
simplify grepping for users of that value?
Olaf

HYBRID: memory mapped IO
...pet() in linux wants to do mmio. It calls ioremap_pte_range
to map phys addr to a VA. Xen then updates the PV dom0''s L1 with
requested io attributes. I''m trying to figure how to do this for PV in
HVM container. I was hoping to update the EPT directly.
I was thinking of just doing guest_physmap_add_entry() but the mfn is not
going to be valid. Is there any other code path that will let me do this?
Another possiblity would be handle_mmio().
thanks,
Mukesh
