STRUCT TEE_CMD_OPEN_SESSION(9)

🎀 struct tee_cmd_open_session(9) 🎀

okay bestie, so this is a page from the Kernel API Manual and it's literally all about struct tee_cmd_open_session — the command you send to call TA_OpenSessionEntryPoint in the TA. yes that's a whole lot of capital letters, but stay with me, it slaps. 💅

---

✨ NAME ✨

struct tee_cmd_open_session — the command to call TA_OpenSessionEntryPoint in TA. that's it, that's the vibe. 🔥

---

🌸 SYNOPSIS 🌸

here's the struct in all her glory, no cap, copy it exact:

struct tee_cmd_open_session {
    u32 ta_handle;
    u32 session_info;
    struct tee_operation op;
    u32 return_origin;
 };

🦋 Members 🦋

okay so let's meet the members, they're all main characters:

• ta_handle — [in] the handle of the loaded TA. like, the TA you already loaded, she's here, this is her ticket 🎫
• session_info — [out] a pointer to the TA allocated session data. the TA's handing you her session tea 🍓
• op — [in/out] the operation parameters. going in, coming out, living her best bidirectional life 🔁
• return_origin — [out] the origin of the return code after TEE processing. so when it comes back, this tells you where that return code came from, iykyk 🌈
