<p> Hi，Berger， </p>
<p> Thanks. But as I know CRB interface should
be for mobile platform. We just want to
support Windows Server
2012. Currently,the Windows Server 2012 can
find physical TPM2 device. However, for vTPM,
the windows server 2012 virtual machine just
can find a virtual TPM 1.2 device and can not
find vTPM 2.0 device. We have tried linux such
as ubuntu and the ubuntu virtual machine
can find vTPM 2.0 device in seabios 1.10 and
our modified <span lang="EN-US">qemu-kvm-ev-2.6.</span></p>

<div>I couldn't make Windows work with TPM2 and seabios.
However, I have some patch for ovmf to compile TPM2
support in, and it seem to work quite ok. I still have
to figure out some PhysicalPresence issues (using
swtpm/libtpms). I am busy with other projects now, but
you can take a look at the branches (<a

As you can see, work in progress, and help welcome!<br>

Windows seems to need CRB for it to accept the TPM 2... It may work
'better' with UEFI, but the device is also recognized with (patched)
SeaBIOS.<br>
<br>
For Win2012R2 this is also relevant:<br>

<b>主题:</b> Can VTPM2 support WINDOWS<br>
<br>
<p> Hi,all, </p>
<p> We want VTPM2 to support
windows virtual machines. So I want to
know if the current seabios can
support the windows guest OS when the
tpm driver can not be modified. The
host OS we used is CentOS 7.3 and the
seabios version is 1.10.2. The
hypervisor is KVM+QEMU. The windows
version is windows server 2012 that
can automatically support physical
TPM2 chip. </p>
</blockquote>
</blockquote>
<br>
I only ever tried with Windows 10 and that
requires a CRB interface (rather than TIS )
for a TPM2, which we will only get with the
next version of QEMU. I would assume that
this is also the case with windows server
2012.<br>
