Since the vTPM implementations are being incorproated into Xen and possibly upstream Linux, I would like to see if this protocol change could be added before we have significant legacy implementations. If not, I still think it would be useful as either a v2 or negotiated protocol change. The current vTPM protocol is a copy of the network protocol. This was likely done for ease of implementation,

Hi, I hope I''m right here. If not then please point me in the right direction. My problem in short: I have problems using (pinning, mmu_update) physical pages from 0x900000 to 0xB1000 usualy. I''m writing my own little amd64 64bit toy kernel (based on Mini-OS as starting point) for xen and I run into problems with the way the start of day sets up the physical pages. My kernel
