STRUCT MPI3MR_FWEVT(9)

okay so bestie, this is struct mpi3mr_fwevt(9) from the Kernel API Manual, and it's literally the firmware event structure page. We're gonna cover every member, every reference, and every tiny detail — no skipping, no cap. 💅✨

💖 NAME 💖

struct mpi3mr_fwevt — Firmware event structure.

That's the vibe: it's the firmware event structure, and it's lowkey the main character of this whole page. 🫶

✨ SYNOPSIS ✨

here's the exact shape, bestie — keep the punctuation and brackets exactly as they are:

       struct mpi3mr_fwevt {
           struct list_head list;
           struct work_struct work;
           struct mpi3mr_ioc *mrioc;
           u16 event_id;
           bool send_ack;
           bool process_evt;
           u32 evt_ctx;
           u16 event_data_size;
           bool pending_at_sml;
           bool discard;
           struct kref ref_count;
           char event_data[];
        };

That's the struct, fr fr. Every field gets its own little moment below. 🎀

🫶 Members 🫶

• list — list head. yes, that kind of list head. 🔗
• work — Work structure. it's giving "I have work to do" energy.
• mrioc — Adapter instance reference. pointing back at the adapter, iconic.
• event_id — MPI3 firmware event ID.
• send_ack — Event acknowledgment required or not.
• process_evt — Bottomhalf processing required or not.
• evt_ctx — Event context to send in Ack.
• event_data_size — size of the event data in bytes.
• pending_at_sml — waiting for device add/remove API to complete.
• discard — discard this event.
• ref_count — kref count.
• event_data — Actual MPI3 event data.
