STRUCT SL_WH_MPI_TRIGGER_T(9)

💅 struct SL_WH_MPI_TRIGGER_T(9) — Kernel API Manual 🎀

okay bestie, welcome to the Kernel API Manual entry for struct SL_WH_MPI_TRIGGER_T — yes the whole title, we're not abbreviating, she said her full name and she's proud of it ✨

---

🌸 NAME 🌸

struct SL_WH_MPI_TRIGGER_T — the literal definition of an MPI trigger element. that's it, that's the vibe 🦋

---

✨ SYNOPSIS ✨

struct SL_WH_MPI_TRIGGER_T {
    uint16_t IOCStatus;
    uint16_t Reserved;
    uint32_t IocLogInfo;
 };

look at her. three fields. absolutely no notes. icon behavior only 👑

---

🌈 Members 🌈

• IOCStatus — the MPI IOCStatus. it's a uint16_t, she's little but she matters 💖
• Reserved — the reserved field, uint16_t. it's giving "i'm just here so the struct lines up" 🫶
• IocLogInfo — the MPI IocLogInfo, a uint32_t. it can be a specific value, or you can drop 0xFFFFFFFF in there as a wildcard and she'll match everything, no cap 😭🔥

---

🦋 Description 🦋

so here's the tea: this struct defines an MPI IOCStatus/IocLogInfo pair. and like… a pair that, if it ever gets observed, should trigger a DIAG_TRIGGER driver event. that's the whole plot 🎬

it's literally matchmaking for log values — you write down the combo you're watching for, and if that combo shows up, the driver reacts. lowkey obsessed with this level of commitment 💅

okay that's the page bestie!! sign-off time: this cutie lives in ./drivers/scsi/mpt3sas and the date on her birth certificate says October 2026. mwah, go touch some kernel code 💜🌟
