STRUCT TEE_CMD_INVOKE_CMD(9)

💅 struct tee_cmd_invoke_cmd(9) 💅

okay so this page is straight out of the Kernel API Manual, and it’s literally the struct that says “hey TA, go run your command entry point” — bestie, it’s giving kernel-to-TA hotline. 💖

✨ NAME ✨

struct tee_cmd_invoke_cmd — a command to call TA_InvokeCommandEntryPoint() in TA. no cap, that’s the whole vibe. 🎀

🦋 SYNOPSIS 🦋

struct tee_cmd_invoke_cmd {
    u32 ta_handle;
    u32 cmd_id;
    u32 session_info;
    struct tee_operation op;
    u32 return_origin;
};

🌸 Members 🌸

• ta_handle — [in] handle of the loaded TA. like, which TA are we even talking to? this is the tag. 🏷️
• cmd_id — [in] TA command ID. the actual “do the thing” number. ✨
• session_info — [in] pointer to TA allocated session data. yes bestie, pointer, and yes it’s TA-allocated. 🫶
• op — [in/out] operation parameters. info goes in, info comes out, main character energy both ways. 🔁
• return_origin — [out] origin of return code after TEE processing. it tells you where the return code came from after the TEE does its thing. 💅
