STRUCT MPI3MR_ALL_TGT_INFO(9)

💖 NAME 💖

okay so bestie, struct mpi3mr_all_tgt_info — and yes this is straight out of the Kernel API Manual — is literally the target device mapping info that the driver hands back to you. like, it's the receipts for every target in the driver's little inventory 🎀 no cap.

✨ SYNOPSIS ✨

struct mpi3mr_all_tgt_info {
    __u16 num_devices;
    __u16 rsvd1;
    __u32 rsvd2;
    struct mpi3mr_device_map_info dmi[1];
 };

look at her. iconic. the dmi[1] at the end? that's the main character energy, iykyk 💅

🦋 Members 🦋

• num_devices — a __u16 telling you exactly how many devices are chilling in the driver's inventory. the headcount, fr fr 🍓
• rsvd1 — Reserved. __u16. not for you, bestie, it's reserved 🙈
• rsvd2 — Reserved. __u32. also not for you. also reserved. we respect her privacy 💀
• dmi — Variable length array of mapping information of targets ✨ it's giving flexible array member, it's giving "the actual good stuff lives here" 🌈

side note: the three reserved fields are literally reserved — don't go poking at them and expecting lore that isn't in the manpage 🙏
