STRUCT MEI_LB2_REQ(9)

💖 struct mei_lb2_req(9) — like, the Late Binding2 request 💖

okay bestie, so this is a page from the Kernel API Manual and it's all about struct mei_lb2_req, which is literally the Late Binding2 request. no cap, that's the whole vibe. it's a struct, it's in the kernel, and it's about to get explained to you in full. 🦋

✨ SYNOPSIS ✨

struct mei_lb2_req {
    struct mei_lb2_header header;
    __le32 type;
    __le32 flags;
    __le32 reserved;
    __le32 total_payload_size;
    __le32 payload_size;
    u8 payload[];
 };

look at her. main character struct energy. 💅

🎀 Members 🎀

• header — the common command header, like every good request needs one 💖
• type — what kind of Late Binding payload this is (check enum intel_lb_type, iykyk)
• flags — flags that get passed straight to the authentication firmware (MEI_LB2_FLAG_*)
• reserved — reserved for future use by the authentication firmware, and it must be set to 0. not optional, bestie, set it to 0 🙈
• total_payload_size — size of the whole Late Binding package, in bytes ✨
• payload_size — size of the payload chunk, in bytes 🌸
• payload — the actual data chunk being sent to the authentication firmware, the moment we've all been waiting for 👑
