STRUCT QCOMTEE_ASYNC_MSG_HDR(9)

💖 STRUCT QCOMTEE_ASYNC_MSG_HDR — a.k.a. the async message header format ✨

okay so this is a page straight outta the Kernel API Manual, and it's honestly kind of a tiny one but it's important, so bestie grab your iced coffee 🍓 and let's get into it.

---

🌸 NAME 🌸

struct qcomtee_async_msg_hdr — the asynchronous message header format, no cap 💅

---

🎀 SYNOPSIS 🎀

struct qcomtee_async_msg_hdr {
    u32 version;
    u32 op;
};

that's the whole struct. two little u32s. iconic behavior honestly 👑

---

🦋 Members 🦋

• version — the current async protocol version of the remote endpoint. it's giving "hi, this is what I speak" energy 🫶
• op — the async operation. literally just. the op. 💀

---

✨ Description ✨

so here's the tea ☕ — version tells you which async protocol the endpoint (that's either QTEE or the driver, iykyk) actually supports.

like, for example: if QTEE sets version to QCOMTEE_ASYNC_VERSION_1_1, then QTEE handles operations supported in QCOMTEE_ASYNC_VERSION_1_1 or QCOMTEE_ASYNC_VERSION_1_0. so it's backwards-compatible-ish, very demure, very mindful 💖

and op? op is the main character that determines the message format. periodt. 🔥

ngl this one's short but you cannot skip it — version and op are doing all the heavy lifting and you gotta respect it 🙈
