[Xen-devel] Any available page table entry bits in Xen??
Hi, I'm working on Xen 3.2.1 and
I'd like to know if there's any available bit in page table entries, on
x86_32 (no pae),
especially on L1 page table entry. It seems to me that all bits are used
by Xen.
Xen disallows all AVAIL bits and PCD/PWT/PAT bits to their guest and use
them all?
I've tried PCD/PWT/AVAIL bits but I couldn't find any availables.
(didn't try PAT)
Or it was my mistake?
I'd like to know exactly what bits in page table I can safely and
exclusively use in Xen..
Any available bit in page table entry or ideas?
thank you in advance!!
Min
