STRUCT SL_WH_MPI_TRIGGERS_T(9)

🌸 struct SL_WH_MPI_TRIGGERS_T(9) 🌸

okay so this is straight out of the Kernel API Manual, bestie — it's the <rainbow>struct SL_WH_MPI_TRIGGERS_T</rainbow> page and it's literally the glow-up guide for a struct that sysfs passes around. Think of it as the little container that holds a whole list of MPI IOCStatus/IocLogInfo pairs, and each of those pairs is like "hey, if you ever see this, fire off a DIAG_SERVICE event." 💅

✨ NAME ✨

struct SL_WH_MPI_TRIGGERS_T — the structure that gets passed to and from sysfs, holding a list of MPI IOCStatus/IocLogInfo pairs that should trigger a DIAG_SERVICE event when observed. 🫶

---

🦋 SYNOPSIS 🦋

struct SL_WH_MPI_TRIGGERS_T {
    uint32_t ValidEntries;
    struct SL_WH_MPI_TRIGGER_T MPITriggerEntry[NUM_VALID_ENTRIES];
 };

no cap, that's the whole shape of it 💖

---

🎀 Members 🎀

• ValidEntries — a uint32_t that says how many _SL_WH_MPI_TRIGGER_T structures are actually chilling inside this structure. like a headcount for the trigger party 👑
• MPITriggerEntry — the actual list of MPI IOCStatus/IocLogInfo trigger elements. this is the lineup, the main characters, the array of NUM_VALID_ENTRIES slots 🌟

---

🌈 Description 🌈

so this binary structure is transferred via sysfs to get/set MPI Error Triggers in the Linux Driver. that's it, that's the whole vibe — sysfs in, sysfs out, triggers configured. it's giving "small struct, big responsibilities" honestly 😌
