Kevin,
Thanks for your reply.
It doesn't require additional seabios patches before it is useful. These
patches
Should work with:
[PATCH v3 0/7] vTPM: Xen stubdom vTPM for HVM virtual machine
--(Xen patch)
[PATCH v4 0/5] QEMU:Xen stubdom vTPM for HVM virtual machine
--(Qemu patch)
I have committed but not upstream. I will forward them to you at next thread.
Thanks
