tpm_tis_clkrun_enable(9)

📦 version 7.3.1, in nixpkgs unstable

okay so this is tpm_tis_clkrun_enable(9) from the Kernel API Manual, and we're about to make the clkrun protocol behave for the entire duration of a single TPM command ✨ no cap, it's giving very specific kernel business.

✨ NAME ✨

tpm_tis_clkrun_enable — keep clkrun protocol disabled for the entire duration of a single TPM command 💅

🦋 SYNOPSIS 🦋

void tpm_tis_clkrun_enable (struct tpm_chip *chip , bool value );

💅 ARGUMENTS 💅

  • chip — the TPM chip to use 🫶
  • value — the switch that decides the CLKRUN protocol vibe:
    • 1 — disable CLKRUN protocol, so that clocks are free running ⚡
    • 0 — enable CLKRUN protocol 🌸
bestie, call this function directly in tpm_tis_remove in the error or driver removal path, since chip->ops is set to NULL in tpm_chip_unregister 😭 this part is important, fr fr.
