🌸 NAME 🌸

like, the whole point is the re-init. don't sleep on it.

that's the whole signature, no cap. returns void — it gives nothing back and honestly? relatable. 🫶

🎀 ARGUMENTS 🎀

  • buf — a tpm_buf. the buffer getting its glow-up. the one being re-initialized. treat her well 💖
  • tag — the tag, and it's gotta be one of these three, fr fr:
    • TPM_TAG_RQU_COMMAND
    • TPM2_ST_NO_SESSIONS

ngl the whole posse lives over in ./drivers/char/tpm, and this page dropped October 2026 in the Kernel API Manual — so yeah, that's the source, the version and the date, all in one cute little sign-off. stan. 💜🧚‍♀️
