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.

On Linux it seems to access the TPM emulator with the normal tpm_tis driver.
Regards,
Stefan
