STRUCT TI_MSGMGR_MESSAGE(9)

🎀 struct ti_msgmgr_message(9) 🎀

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil struct page and honestly it's giving "small but mighty" — it's the Message Manager structure, and if you're doing TI mailbox stuff you're gonna want to know her 💅

---

✨ NAME ✨

struct ti_msgmgr_message — the Message Manager structure, no cap 💖

---

🌸 SYNOPSIS 🌸

struct ti_msgmgr_message {
    size_t len;
    u8 *buf;
    struct mbox_chan *chan_rx;
    int timeout_rx_ms;
 };

like, that's the whole vibe right there 🫶

---

🦋 Members 🦋

• len — the length of the data in the Buffer 📏
• buf — the Buffer pointer, literally just a pointer to the buffer 🎀
• chan_rx — the expected channel for the response. heads up: you must provide this if you wanna use polled rx 👑
• timeout_rx_ms — the Timeout value to use if you're polling for a response ⏱️

---

💜 Description 💜

So this is the structure for the data used in mbox_send_message ✨ and here's the tea: the length of the data buffer you use depends on the SoC integration parameters — each message may be 64, 128 bytes long depending on the SoC 😭 so the client is supposed to be aware of this, fr fr. don't come for me if you assumed one size fits all 💀
