UNION MPI3MR_TRIGGER_DATA(9)

💖 union mpi3mr_trigger_data(9) 💖

okay so bestie, welcome to the Kernel API Manual — that's the manual name, we're not copying the header line, iykyk — and today's main character is a lil union called union mpi3mr_trigger_data. it's giving "small but holds multitudes" honestly 🫶

---

✨ NAME ✨

union mpi3mr_trigger_data — trigger data information 💅

like, it literally is the trigger data info. that's the whole vibe.

---

🌸 SYNOPSIS 🌸

union mpi3mr_trigger_data {
    u16 fault;
    u64 global;
    union mpi3_driver2_trigger_element element;
 };

look at her. three members, one union, zero notes. slay ✨

---

🎀 Members 🎀

• fault — the fault code 💀 (literally just: fault code)
• global — global trigger data 🌍
• element — the element trigger data 🧚

that's it. that's the whole members section. don't overthink it bestie 💜

okay this is the part where she name-drops literally everyone at the party. and because we're not skipping anything, here's the entire guest list, no cap 🔥

count 'em. all there. periodt 💅

ngl bestie, this page is short but she's important — you don't get a union with a u64 global and a nested union mpi3_driver2_trigger_element element for no reason. main character energy fr fr 🌈

⭐ the cute sign-off ⭐

this iconic little page lives in ./drivers/scsi/mpi3mr, and it's dated October 2026 — so yeah, she's from the future, we stan a time traveler 🦋✨

okay bye bestie, go read the other 32 cross-references, love u 💖🌸🎀
