psp_tee_process_cmd(9)

💖 NAME 💖

Okay so welcome to the psp_tee_process_cmd(9) page in the Kernel API Manual, bestie. This one is all about psp_tee_process_cmd — process command in Trusted Execution Environment, aka TEE. 👑

✨ SYNOPSIS ✨

int psp_tee_process_cmd (enum tee_cmd_id cmd_id , void *buf , size_t len
, u32 *status );

🫶 ARGUMENTS 🫶

• cmd_id — the TEE command ID, typed as enum tee_cmd_id. This is the command you're sending in. 💌
• buf — command buffer for TEE processing. On success, it gets updated with the response. So yeah, it comes back changed — main character energy. ✨
• len — length of the command buffer in bytes. Gotta know how much buffer we're working with. 📏
• status — on success, this holds the TEE command execution status. It's giving "receipts from the TEE." 🧾

🌸 DESCRIPTION 🌸

So this function submits a command to the Trusted OS for processing in the TEE environment, then it waits for a response or until the command times out. That's the whole vibe: send the command, wait for the answer, or hit the timeout. ⏳

🔥 RETURN 🔥

Return values, bestie — memorize these:

• 0 — TEE successfully processed the command. Slay. ✅
• -ENODEV — PSP device not available. Not the moment. 😭
• -EINVAL — invalid input. Check yourself before you wreck yourself. 🙈
• -ETIMEDOUT — TEE command timed out. It literally took too long. 💀
• -EBUSY — PSP device is not responsive. It's not answering the group chat. 📵
