STRUCT MPI3_DRIVER_INFO_LAYOUT(9)

💅 struct mpi3_driver_info_layout(9) — Kernel API Manual, but make it make sense ✨

okay so bestie, welcome to the kernel API manual for struct mpi3_driver_info_layout(9) 🎀 literally the little info blob that tells you all about a driver. think of it as the driver's lil ID card, fr fr.

---

✨ NAME ✨

struct mpi3_driver_info_layout — Information about driver 🫶

---

🌸 SYNOPSIS 🌸

here's the whole struct, character for character, no cap:

struct mpi3_driver_info_layout {
    __le32 information_length;
    __u8 driver_signature[12];
    __u8 os_name[16];
    __u8 os_version[12];
    __u8 driver_name[20];
    __u8 driver_version[32];
    __u8 driver_release_date[20];
    __le32 driver_capabilities;
 };

she's giving "i contain multitudes" and honestly? she does 💜

🦋 Members 🦋

okay so let's meet the cast, one by one 👑

• information_length — the length of this structure, in bytes. yes bestie, it measures itself. self-aware icon behavior 💅
• driver_signature — the Driver Vendor name 🏷️
• os_name — Operating System Name 🖥️
• driver_name — Driver name ✨
• driver_version — Driver version 🔢
• driver_release_date — Driver release date 📅
• driver_capabilities — Driver capabilities 🔥

ok so real talk: os_version is sitting right there in the struct up top but the Members list doesn't give it its own little blurb. not me noticing 👀 — just keeping it 100 with you, bestie. we don't invent info around here 🙈
