STRUCT MPI3MR_NVME_PT_SGE(9)

🦋 struct mpi3mr_nvme_pt_sge(9) — Kernel API Manual 🦋

Okay bestie, welcome to the Kernel API Manual — today we’re talking about struct mpi3mr_nvme_pt_sge(9), and it’s lowkey here to handle some very specific struct business 💅

✨ NAME ✨

struct mpi3mr_nvme_pt_sge — structure to store SGEs for NVMe Encapsulated commands. That’s the whole vibe 🫶

🌸 SYNOPSIS 🌸

The struct layout is giving exactly this, no cap:

struct mpi3mr_nvme_pt_sge {
    __le64 base_addr;
    __le32 length;
    u16 rsvd;
    u8 rsvd1;
    u8 sub_type:4;
    u8 type:4;
};

💅 Members 💅

• base_addr — physical address 💫
• length — SGE length, literally
• rsvd — reserved 🚫
• rsvd1 — reserved too, bestie 🚫
• sub_type — sgl sub type
• type — sgl type
