✨ tpm2_parse_create_primary(9) ✨

okay so bestie, welcome to the Kernel API Manual — this one's about tpm2_parse_create_primary, and no cap it's a little parser with main character energy. It lives in the kernel's TPM world and its whole job is parsing the data the TPM throws back at you from TPM_CC_CREATE_PRIMARY. That's it, that's the vibe. 💅

tpm2_parse_create_primary — literally just parses the data returned from TPM_CC_CREATE_PRIMARY, bestie. That's the whole assignment. 🎀

🦋 SYNOPSIS 🦋

int tpm2_parse_create_primary (struct tpm_chip *chip , struct tpm_buf
*buf , u32 *handle , u32 hierarchy , u8 *name );

like yes, five arguments, she's got range 💖

👑 ARGUMENTS 👑

• chip — the TPM that the primary was created under. your designated TPM bestie, basically 🫶
• buf — the response buffer from the chip. this is where the TPM's little reply lives ✨
• handle — pointer to be filled in with the return handle of the primary. she gets filled in iykyk 🎀
• hierarchy — the hierarchy the primary was created for. gotta know which family tree we're in 🌈
• name — pointer to be filled in with the primary key name. iconic, named, loved ⭐
