mpi3mr_event_trigger(9)

💅 mpi3mr_event_trigger(9) 💅

ok so this is a page from the Kernel API Manual bestie, and we're talking about mpi3mr_event_trigger — the MPI event HDB trigger handler. yes it's a mouthful, no i will not be shortening it, we respect the function name in this house 🫶

---

✨ NAME ✨

mpi3mr_event_trigger — literally the MPI event HDB trigger handler 🌸

---

🦋 SYNOPSIS 🦋

void mpi3mr_event_trigger (struct mpi3mr_ioc *mrioc , u8 event );

that's the whole vibe. void return, two args, we move 💅

---

🎀 ARGUMENTS 🎀

• mrioc — your adapter instance reference 🖇️ like, the actual controller you're talking about
• event — the MPI Event. yes that's it. that's the whole description. iconic minimalism honestly 👑

---

💖 DESCRIPTION 💖

okay so here's what she does, and it's lowkey simple but highkey important:

this function compares the event trigger values with the driver page 2 values, and if it finds a match — boom — it calls the generic trigger handler to release the HDBs ✨

so like: compare, match, release. the holy trinity. no cap 🧚

---

🌈 RETURN 🌈

nothing. void. she gives you no data back, she just does the thing and dips 🙈💀

lowkey a reminder: this whole page lives under ./drivers/scsi/mpi3mr and it's dated October 2026, so jot that down bestie 🗓️

and that's the tea 💅 stay slaying, go release those HDBs, mwah 🎀💖🔥
