tpm2_load_cmd(9)

tpm2_load_cmd(9) 💅

okay so this little icon is straight out of the Kernel API Manual, and it's literally the function that executes a TPM2_Load command. no cap, it's giving "load the key into the TPM" energy. 🫶

✨ NAME ✨

tpm2_load_cmd — execute a TPM2_Load command. that's it, that's the whole vibe. 💖

🌸 SYNOPSIS 🌸

int tpm2_load_cmd (struct tpm_chip *chip , struct trusted_key_payload *payload , struct trusted_key_options *options , u32 *blob_handle );

🎀 ARGUMENTS 🎀

• chip — TPM chip to use. your main character TPM, basically. 👑
• payload — the key data in clear and encrypted form. both forms, bestie — it's got layers. 🍓
• options — authentication values and other options. all the auth-y bits and extra settings. 🔥
• blob_handle — returned blob handle. that's what comes back out. ✨

💀 RETURN 💀

• 0 on success. slay. ✅
• -E2BIG on wrong payload size. wrong payload size, not the vibe. 😭
• -EPERM on tpm error status. the TPM is not having it. 🙈
• < 0 error from tpm_send. anything less than zero means tpm_send said nope. 💔
