mpi3mr_process_trigger(9)

💅 mpi3mr_process_trigger — like, the Kernel API Manual page you actually wanna read 🎀

okay so bestie, welcome to the mpi3mr_process_trigger(9) page 💖 this one lives in the Kernel API Manual, and it's lowkey the generic HDB trigger handler. yes, THE one. let's get into it.

---

✨ NAME ✨

mpi3mr_process_trigger — the generic HDB Trigger handler, periodt 💅

---

🌸 SYNOPSIS 🌸

void mpi3mr_process_trigger (struct mpi3mr_ioc *mrioc , u8 trigger_type
, union mpi3mr_trigger_data *trigger_data , u8 trigger_flags );

she takes four things and returns absolutely nothing, and honestly? iconic.

---

🦋 ARGUMENTS 🦋

• mrioc — the adapter instance reference 🫶 like, which controller are we even talking to, yk?
• trigger_type — the trigger type ✨ (that's the whole vibe of the trigger)
• trigger_data — the trigger data 🌈 everything the trigger's carrying around
• trigger_flags — the trigger flags 🎀 the little flag bits, as one does

---

💜 DESCRIPTION 💜

so what she does is: this function checks the validity of HDB and triggers, and then — based on the trigger information — creates an event to be processed in the firmware event worker thread 🔥 that's it, that's the whole job. main character energy fr fr.

⚠️ okay listen, this is the important bit: this function should be called with the trigger spinlock held 😭 no cap. don't be out here calling her unlocked, that's not the vibe.

---

👑 RETURN 👑

Nothing. literally nothing. she returns void and she's at peace with that 💀✨
