Subject: DOM0_GETPAGEFRAMEINFO for non-dom0 domains
Date: Tue, 16 Aug 2005 17:23:13 +0200	[thread overview]
Message-ID: <430204E1.3030006@diku.dk> (raw)

hi,

with writable page tables it takes a little more work tracking page
types from within a domU. Basically, I need to duplicate Xen's pgd walks
when pinning and unpinning pgds, within the domU, in order to obtain a
consistent map of page types for my own pages.

It seems it would be a lot easier just to allow domUs access to a
DOM0_GETPAGEFRAMEINFO-like hypercall that would extract this info from
Xen. Would you consider merging a patch to do this, and how/where would
you prefer it to be implemented?

thanks,
Jacob
