✨ tpm2_startup(9) ✨

bestie, welcome to the Kernel API Manual page for tpm2_startup — it's literally about turning the TPM on. no cap. 💖

🌸 NAME 🌸

• tpm2_startup — turn on the TPM 💅

🎀 SYNOPSIS 🎀

int tpm2_startup (struct tpm_chip *chip );

🦋 ARGUMENTS 🦋

• chip — TPM chip to use. that's the whole argument, icon. 🫶

💜 DESCRIPTION 💜

okay so normally the firmware should start the TPM. that's the default plan, main character firmware energy and all. This function is provided as a workaround if this does not happen. A legal case for this could be for example when a TPM emulator is used. so if your TPM needs a little push, this is the push, and if you're running a TPM emulator, it's a legal case, iykyk. ✨

🔥 RETURN 🔥

same as tpm_transmit_cmd. that's it, that's the return vibe. 😭
