ENUM SYS_T_MESSAGE_SBD_SUBTYPE(9)

✨ enum sys_t_message_sbd_subtype(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — we're looking at enum sys_t_message_sbd_subtype, and honestly? it's giving "small enum, big purpose" 💅

---

🌸 NAME 🌸

enum sys_t_message_sbd_subtype — the SyS-T SBD message subtypes, aka the two little labels that tell you how chunky your message ID is 🎀

---

🦋 SYNOPSIS 🦋

enum sys_t_message_sbd_subtype {
    MIPI_SYST_SBD_ID32 ,
    MIPI_SYST_SBD_ID64

};

that's the whole thing. two members. no cap, that's it. ✨

---

💖 Constants 💖

• MIPI_SYST_SBD_ID32 — an SBD message carrying a 32-bit message ID 🍓
• MIPI_SYST_SBD_ID64 — an SBD message carrying a 64-bit message ID 👑

like, pick your fighter: smol ID or big ID, both iconic, both valid 💅

🌈 Description 🌈

so here's the vibe check on Structured Binary Data messages: they can send information of arbitrary length, and they come with IDs that describe a BLOB's content and layout 🫶

literally the ID is the main character explaining what the BLOB actually is — content AND layout, both, at the same time, we love a multitasker 😭🔥

🔥 SEE ALSO 🔥

Kernel file ./drivers/hwtracing/stm/p_sys-t.c — go read it, iykyk 📖✨

ngl this one's short and sweet, but every single member matters — don't go renaming things, fr fr 🙈

mwah 💋 that's the page, bestie — brought to you by the ./drivers/hwtracing/stm directory, dated October 2026, living under the title enum sys_t_m..._sbd_subtype(9) 🧚‍♀️💜
