💅 tpm_cr50_check_locality(9) — the Kernel API Manual glow-up

okay so bestie, welcome to tpm_cr50_check_locality(9) ✨ this is the kernel API page for it, and honestly? it's a little one but it's doing its job and we respect it 🫶

🌸 NAME 🌸

tpm_cr50_check_locality — literally just verifying that the TPM locality you need is actually active. that's the whole vibe check 👑

🦋 SYNOPSIS 🦋

int tpm_cr50_check_locality (struct tpm_chip *chip , int loc );

no cap, that's the whole signature. she's compact 💅

🎀 ARGUMENTS 🎀

  • chip — a TPM chip. that's it, that's the whole description, she's a chip and we love her 🧚
  • loc — the locality you want verified. like, "is this locality active or not" energy ⭐

🔥 RETURN 🔥

here's what you get back, and it's giving two options only 😭

  • loc — Success. yes, it returns the locality value itself on success, iconic behaviour fr fr 👑
  • -errno — a POSIX error code. the classic "something's off" situation 💀

🌈 SEE ALSO 🌈

the whole friend group, iykyk 💜

kernel file ./drivers/char/tpm/tpm_tis_i2c_cr50.c and the struct tpm_i2c_cr50_priv_data(9) — plus literally all of these:

like, the whole squad showed up to the function's birthday party 🎂💖

💡 friendly reminder: loc in the RETURN section means the locality value coming back at you — don't get it twisted with the loc argument, they're the same name but she's wearing two different outfits okay 💅

and that's the page!! this one lives under ./drivers/char/tpm, dated October 2026, and it's the tpm_cr50_check_locality(9) manual page — periodt. go check those localities, bestie, you got this 🦋✨💜
