mpt3sas_trigger_mpi(9)

💅 mpt3sas_trigger_mpi — the MPI trigger handler, bestie

okay so picture this: we're deep in the kernel, section 9 of the Kernel API Manual, and the function on the cover is mpt3sas_trigger_mpi. Say it with me — em-pee-eye trigger handler ✨ It's the lil' handler that deals with MPI triggers, and honestly? It's giving "quietly doing its job in the SCSI stack" energy.

✨ NAME ✨

mpt3sas_trigger_mpi — the MPI trigger handler 🎀

---

🦋 SYNOPSIS 🦋

void mpt3sas_trigger_mpi (struct MPT3SAS_ADAPTER *ioc , u16 ioc_status ,
u32 loginfo );

Not me writing out the signature exactly — yes, all three args, in that order, void return, no cap. 📝

---

🌸 ARGUMENTS 🌸

• ioc — the per adapter object 🫶 like, the whole adapter, cosied up in one pointer.
• ioc_status — ? 🙈 bestie the docs literally just say ?. That's it. That's the whole description. I'm not gonna invent lore for it, so ? it stays.
• loginfo — also ? 💀 same situation, the manual gives us a question mark and honestly? We respect it.

lowkey iconic that two of the three arguments are documented as ? — not me defending it, just saying the manpage said what it said and I'm not about to make stuff up 💅
