STRUCT SL_WH_SCSI_TRIGGER_T(9)

💅 struct SL_WH_SCSI_TRIGGER_T(9) 💅

okay bestie, welcome to the Kernel API Manual entry for struct SL_WH_SCSI_TRIGGER_T — yes that's a whole mouthful, no I will not be pronouncing it out loud. come sit, this one's actually cute and short 🎀

---

✨ NAME ✨

struct SL_WH_SCSI_TRIGGER_T — the literal definition of a SCSI trigger element. that's it. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

okay so here's the shape of it, copy it exactly, no freestyling:

struct SL_WH_SCSI_TRIGGER_T {
    U8 ASCQ;
    U8 ASC;
    U8 SenseKey;
    U8 Reserved;
 };

four little U8 fields. tiny. iconic. like a friendship bracelet but for kernel hardware events 💖

👑 Members 👑

here's the group chat roster, one by one:

• ASCQ<|place_holder_mm_span_0442|> — nope sorry, that's ASCQ 💀 — Additional Sense Code Qualifier. it can be a specific value, or 0xFF for wildcard. wildcard means "any of them bestie, we don't care" 🃏
• ASC — Additional Sense Code. again, can be specific or 0xFF for wildcard. yes, same energy as ASCQ, no cap ✨
• SenseKey — the SCSI Sense Key. that's it, that's the whole description. she's mysterious, she's lowkey 🔥
• Reserved — literally just reserved. leave her alone, she's resting 🙈

---

🧚 Description 🧚

okay so the whole point of this struct: it defines a sense key — single or many variants — that should induce a DIAG_TRIGGER driver event if observed. so like, if the driver sees this sense key out in the wild, it goes "OH 👀" and fires the trigger. main character energy fr fr 💫

🌈 SEE ALSO 🌈

go read these next, i'm obsessed with a good cross-reference chain:

• Kernel file ./drivers/scsi/mpt3sas/mpt3sas_trigger_diag.h
• struct SL_WH_EVENT_TRIGGER_T(9)
• struct SL_WH_EVENT_TRIGGERS_T(9)
• struct SL_WH_SCSI_TRIGGERS_T(9)
• struct SL_WH_MPI_TRIGGER_T(9)
• struct SL_WH_MPI_TRIGGERS_T(9)
• struct SL_WH_TRIGGERS_EVENT_DATA_T(9)

like a little family of trigger structs, all matching, all slaying 💜

---

lowkey reminder: the wildcard value is 0xFF for both ASCQ and ASC — don't mix that up bestie, i'm begging 🫶
