💖 TCTI-I2C(7) 💖

okay bestie, pull up a chair, we're reading a Miscellaneous Information Manual page and honestly? it's giving niche and iconic. this one lives in section 7 of the manual, and its whole name is TCTI-I2C(7). yes the title is literally in the header and the footer, that's just how manpages do, they're extra like that 💅

✨ NAME ✨

tcti-i2c-helper — the device driver TCTI library 🦋

🌸 SYNOPSIS 🌸

so basically:

  • a TPM Command Transmission Interface (TCTI) module for communication via I2C 🔥
  • TPM device driver

that's it, that's the whole vibe check, short and slay ✨

🎀 DESCRIPTION 🎀

tcti-i2c-helper is a library that abstracts the details of communication with a TPM via the I2C protocol. no cap. it handles all the messy behind-the-scenes stuff so you don't have to ✨

the way it stays platform independent?? obsessed. it does this by using user supplied methods for I2C and timing operations — meaning you bring the platform-specific bits, and it handles the TPM conversation.

those methods get supplied to Tss2_Tcti_I2c_Helper_Init via the TSS2_TCTI_I2C_HELPER_PLATFORM struct. that's the handoff point, that's the moment, that's where your stuff meets its stuff 🫶
