Is there anything which is actually Xen specific about the driver
in tpm.[ch]? Would it be better to just probe for it, perhaps
gates by a Kconfig option which enables TPM support.
I also think the probing should be done. That code can also be
recycled from what I posted earlier. It's gated by a Kconfig
option, so it doesn't
fill up the 128k ROM.
Stefan
Agree, I will do it ASAP.
I reposted v9 of my series of patches. I will probably post v10 today.
Please try that one then since these patches should cover Xen, QEMU
(using a driver that only I can test at the moment), and to some
extent bare metal system.
Stefan
Great! Could you also archive v10 to your github?
then I can also test it and go through these source code.
I put it here now:

Stefan
Thanks.
MS windows guest VM are maybe tricky issues. In my early-stage SeaBios patch,
I deal with TPM TCPA and SSDT in SeaBios, but MS windows guest VM is blue
screens(Linux guest virtual machines are working).
It works when I deal with TPM TCPA and SSDT in hvmloader for Windows guest VM.
Can you be a bit more specific as to what gets it to work or which
modifications you have to make in SeaBIOS to make it work?
Stefan
