Re: [Xen-users] [Xen-devel] How to use the vTPM backend driver in the pv-ops kernel

["Fioravante, Matthew E." <Matthew.Fioravante@xxxxxxxxxx>]

The frontend driver is currently being ported to the latest kernel. You can 
find the patch cross listed here as well as the linux kernel mailing list.

I have no plans to port the backend driver. If you need it you'll have to get 
it from the 2.6.18
kernel and port it yourself.
