✨ NAME ✨

okay so bestie, this page is TCTI-SPI(7) from the Miscellaneous Information Manual — and the star of the show is tcti-spidev, the TCTI library for accessing TPMs via spidev. 🎀

🌸 SYNOPSIS 🌸

It's a TPM Command Transmission Interface (TCTI) module for interaction with a TPM that is attached to an spidev device node. That's it, that's the whole vibe. 🦋

💅 DESCRIPTION 💅

tcti-spidev is a library that abstracts the details of communication with a TPM that is attached to an spidev device node. It handles all the messy little comms stuff so you don't have to, no cap. 🔥

The interface exposed by this library is defined in the “TSS System Level API and TPM Command Transmission Interface Specification” specification. Iconic spec name, we love a long title.

The configuration of this TCTI takes the filepath to the device node.

Default: /dev/spidev0.1 — that's the default, bestie, write it down. ✍️
