[Xen-devel] Request to backport 23511:450f1d198e1e to testing branches.
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. -- Andrew Cooper - Dom0 Kernel Engineer, Citrix XenServer T: +44 (0)1223 225 900, http://www.citrix.com _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
