💅 tpm_cr50_request_locality(9) — kernel API manual, bestie edition ✨

okay so bestie, you're looking at the manual page for tpm_cr50_request_locality — yes that's the whole name, it's giving "my parents gave me a very specific name" energy, but it's iconic and it does exactly one thing. this is the kernel API manual for it, and we're gonna get through it together, no cap 🫶

🌸 NAME 🌸

tpm_cr50_request_locality — request TPM locality. that's it. that's the whole vibe. one job, done beautifully 💅

✨ SYNOPSIS ✨

int tpm_cr50_request_locality (struct tpm_chip *chip , int loc );

literally just call it with a chip and a locality and it returns an int. simple. clean. main character energy 👑

🎀 ARGUMENTS 🎀

  • chip — a TPM chip. you know, the chip. the TPM one. bestie, hand it over 🫴
  • loc — the locality you wanna request. which locality? that one. the one you're asking for. 💫

🦋 RETURN 🦋

  • loc — Success. 🎉 so if you get your locality back, that's a win, we love that for you.
  • -errno — a POSIX error code. 😭 okay so if things go sideways it hands you a negative errno instead, and you deal with it like the strong independent kernel dev you are.
ngl, the return value lowkey being the same value you passed in for success is a whole mood. but that's what it says, so that's what we're saying. periodt.
