Hi,
Now I have enabled the below 2 features on TPM 2.0 / TPM 1.2 hardware. These 2 features are compatible with community vtpm architecture.
1. vTPM for PV virtual machine on TPM2.0.
2. vTPM for HVM virtual machine on TPM 1.2.
Feature 1, vtpm for PV virtual machine on TPM 2.0. TPM 2.0 is not backward compatible with TPM 1.2, I should modify vtpmmgr to communicate directly with TPM 2.0 hardware. it will attempt to take ownership with the supplied owner_auth and then create a TPM storage key which will be used to secure vTPM key data.
Feature 2, vTPM for HVM virtual machine on TPM 1.2. Qemu provides Qemu TPM 1.2 tis emulation, and seabios enables it.
*Qemu tpm1.2 Tis:
Implementation of the tpm1.2 Tis interface for HVM virtual
machines. It is Qemu emulation device.
* XenStubdoms backend:
Qemu vTPM driver. This driver provides vtpm initialization
and sending data and commends to a para-virtualized vtpm
stubdom.
* XenDevOps:
the Xen backend driver, transfer any request from Xenstubdoms backend
to vtpm-stubdom. XenStubdoms backend driver connects to this backend
driver to facilitate communications between vtpm stubdom and XenStrubdoms
backend.

Are you going to post patches? Or did you have a question about this? If
so then I'm afraid I didn't spot it.

Yes, I will post these patches about two weeks later. BTW, These patches should be reviewed and approved by Intel OTC first.
I had ask some question about this, and Graaf answered my question in detail, thanks.

Campbell,
Sorry for delay commit for below 2 features as There were some uncontrollable issues.
1. vTPM for PV virtual machine on TPM2.0.
2. vTPM for HVM virtual machine on TPM 1.2.
I developed these 2 features based on 4.3.0. now there are some confliction with master branch.
How to deal with it?
If I still focus on fixing it to make it compatible with master branch, there is a time delay involved in
this process.
Thanks
Quan Xu

I'm afraid you will have to rebase onto the master branch. Also note
that we are currently in feature freeze for 4.5 so I think this will
have to target 4.6. You should still post your patches as soon as you
can though.
