[Xen-devel] [PATCH] SeaBios/vTPM: Enable Xen stubdom vTPM for HVM virtual machine

[Quan Xu <quan.xu@xxxxxxxxx>]

This patch series are only the SeaBios part to enable stubdom vTPM for HVM
virtual machine. It will work with Qemu patch series and Xen patch series.

========================
    *INTRODUCTION*
========================
The goal of virtual Trusted Platform Module (vTPM) is to provide a TPM 
functionality
to virtual machines (Fedora, Ubuntu, Redhat, Windows .etc). This allows programs
to interact with a TPM in a virtual machine the same way they interact with a 
TPM
on the physical system. Each virtual machine gets its own unique, emulated, 
software
TPM. Each major component of vTPM is implemented as a stubdom, providing secure
separation guaranteed by the hypervisor.

The vTPM stubdom is a Xen mini-OS domain that emulates a TPM for the virtual 
machine
to use. It is a small wrapper around the Berlios TPM emulator. TPM commands are 
passed
from mini-os TPM backend driver.
