STRUCT MPI3MR_BSG_IN_HDB_STATUS(9)

💖 STRUCT MPI3MR_BSG_IN_HDB_STATUS(9) 💖

okay so first things first — we're in the Kernel API Manual bestie, and this is the page for struct mpi3mr_bsg_in_hdb_status. yes the header got cut off, no we're not gonna stress about it, that's just how the terminal renders it. pull up a chair 🎀

---

✨ NAME ✨

struct mpi3mr_bsg_in_hdb_status — this struct is literally the return-data container for the BSG request that retrieves how many host diagnostic buffers the driver supports, what their current status is, plus any additional status-specific data if there is any, delivered as multiple hdb entries. she's the whole info-dump package 💅

---

🦋 SYNOPSIS 🦋

struct mpi3mr_bsg_in_hdb_status {
    __u8 num_hdb_types;
    __u8 element_trigger_format;
    __u16 rsvd2;
    __u32 rsvd3;
    struct mpi3mr_hdb_entry entry[1];
 };

---

🌸 Members 🌸

• num_hdb_types — the number of host diag buffer types that are supported. that's the count, the headcount, the "how many of y'all are there" 🫶
• element_trigger_format — the element trigger format. exactly what it says on the label, no notes ✨
• rsvd2 — reserved. hands off, bestie, she's not for you 🙈
• rsvd3 — also reserved. same energy, equally off-limits 💀
• entry — a variable-length array of diag buffer status entries. variable length meaning she grows to fit, main character energy honestly 👑

okay that's the whole page, you ate that ngl 🍓 — this one's straight out of ./include/uapi/scsi, dated October 2026, and we're officially done. periodt 💅🌈
