Hello!
I maintain the TPM support in QEMU and the TPM emulator (swtpm). I
have a report from a user who would like to use QEMU on ARM64 (aarch64)
with EDK2 and use an attached TPM 2 but it doesn't seem to work for him.
We know that Windows on x86_64 works with EDK2 and can use an attached
TPM 2 (using swtpm). I don't have an aarch64 host myself nor a Microsoft
account to be able to access the Windows ARM64 version, so maybe someone
here has the necessary background, credentials, and hardware to run QEMU
on using kvm to investigate what the problems may be due to on that
platform.
https://github.com/stefanberger/swtpm/issues/493
On Linux it seems to access the TPM emulator with the normal tpm_tis driver.
Regards,
Stefan

Cc'ing Marc-André who is your EDK2 co-maintainer.

and also adding Ard if he is aware of any limitation the TPM2
integration may suffer for Windows support. On my end I am only able to
test on Linux atm.
Thanks

I never tested Windows with the TPM2 support, so I cannot answer this,
unfortunately.

Oops sorry, I meant your EDK2 "co-designated Package
Reviewer"
R: Package Reviewer: Cc address for patches and questions.
Reviewers help maintainers review code, but don't have push access.
A designated Package Reviewer is reasonably familiar with the
Package (or some modules thereof), and/or provides testing or
regression testing for the Package (or some modules thereof),
in certain platforms and environments.
OvmfPkg: TCG- and TPM2-related modules
