Subject: [PATCH V2 0/1] support >3 level p2m tree
Date: Tue, 9 Sep 2014 06:29:24 +0200 [thread overview]
Message-ID: <1410236965-11948-1-git-send-email-jgross@suse.com> (raw)
Pv domains write the mfn of a 3 level p2m tree to arch_shared_info
structure. Consumers of this information are the domain save/restore
functions of the Xen tools.
Being defined as having 3 levels the maximum supported domain size of
64 bit domains is 512 GB. The following patch expands the
arch_shared_info structure to support more levels.
The Xen tools are not covered in this patch as the patch series
"Libxl migration v2 support":
http://lists.xen.org/archives/html/xen-devel/2014-09/msg00427.html
should be applied first.
