TCTI-DEVICE(7)

💖 TCTI-DEVICE(7) 💖

okay bestie, so this is a page from the Miscellaneous Information Manual — yes, that's the manual name, and yes, it's a whole vibe. Let's get into it 🫶

---

✨ NAME ✨

tcti-device — the device driver TCTI library 💅

---

🌸 SYNOPSIS 🌸

It's a TPM Command Transmission Interface (TCTI) module, and its whole job is interacting with the TPM device driver. Simple. Iconic. No notes. ✨

---

🦋 DESCRIPTION 🦋

so tcti-device is a library that abstracts away all the details of talking directly to the device node that the Linux kernel driver exposes — and that node is typically /dev/tpm0 👑

Like, the library handles the direct communication so you don't have to, and the interface it exposes is defined in the “TSS System Level API and TPM Command Transmission Interface Specification” specification. That's the glow-up. That's the whole thing. 🎀
