[Xen-devel] [PATCH v2 0/6] PVH MTRR initial stat

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The following patches set a sane initial MTRR state for both Dom0 and
DomU PVH guests. Note that for Dom0 the host MTRR state is used, OTOH
for DomU the default MTRR type is set to write-back.

This should avoid guests having to setup some kind of MTRR state in
order to boot.

Thanks, Roger.
