This link is entirely useless, and doesn't explain what the problem was and *why* TPM2_TCG_HMAC shouldn't be on by default. I think a much better link is https://lore.kernel.org/linux-integrity/[email protected]/ which talks about the problems that TPM2_TCG_HMAC causes. Which weren't just about "not performing well enough", but actually about how it breaks TPM entirely for some cases. Linus
