[Qemu-devel] [PATCH 0/5] Extend TPM support with a QEMU-external TPM

[Stefan Berger <stefanb@linux.vnet.ibm.com>]

The following series of patches extends TPM support with an
external TPM that offers a Linux CUSE (character device in userspace)
interface. This TPM lets each VM access its own private vTPM.
The CUSE TPM supports suspend/resume and migration. Much
out-of-band functionality necessary to control the CUSE TPM is
implemented using ioctl's.

The series extends the TPM support so far that most functionality of
TPM support on a physical platform is now available to each x86 VM,
this includes the Physical Presence Interface support that has
its counter-part in the SeaBIOS and is implemented using ACPI.
