Subject: Request to backport 23511:450f1d198e1e to testing branches.
Date: Wed, 9 Nov 2011 10:30:05 +0000 [thread overview]
Message-ID: <4EBA562D.8010808@citrix.com> (raw)
c/s 23511:450f1d198e1e prevents cache flushing on AMD Valencia CPUs.
The result of not having this changeset, which we see on our new
hardware, is that HVM operations proceed at a glacial pace. (1 minute
for HVM bios to start, 3 minutes between booting memtest and it actually
starting to test memory. Attempting to install windows gets very boring
very quickly.)
The patch applies cleanly to xen-4.1-testing.
