Ignoring the "work in progress" status of TPM 2 and your https://github.com/stefanberger/swtpm/tree/tpm2-preview branch, should your current code already also work with the qemu device backend that is getting discussed here? In other words, are protocol changes needed? I know that TPM 2 has changed the commands, but I don't know whether that affects also the lower layers. -- Best Regards, Patrick Ohly The content of this message is my personal opinion only and although I am an employee of Intel, the statements I make here in no way represent Intel's position on the issue, nor am I authorized to speak on behalf of Intel on this matter.
