UNION DRM_VMW_GB_SURFACE_CREATE_ARG(9)

🦋 union drm_vmw_gb_surface_create_arg(9) 🦋

okay so bestie, welcome to the Kernel API Manual ✨ this one is a lil union from the vmwgfx world and it's honestly giving "small but important" energy 🎀 she's not flashy, but she's the whole reason a certain ioctl can even happen, iykyk 💅

---

🌸 NAME 🌸

union drm_vmw_gb_surface_create_arg — and that's literally it, the dash after the name is just sitting there empty 😭 no description, no cap, that's the entire NAME section, we move.

---

✨ SYNOPSIS ✨

union drm_vmw_gb_surface_create_arg {
    struct drm_vmw_gb_surface_create_rep rep;
    struct drm_vmw_gb_surface_create_req req;
};

look at her go 💖 two members, one union, absolutely slaying the layout game 👑

---

🫶 Members 🫶

• rep — the output argument, as described above 🫶 she's the one carrying info back out to you.
• req — the input argument, as described above 💜 she's the one you fill in before you knock on the kernel's door.

---

🔥 Description 🔥

she is literally the argument to the DRM_VMW_GB_SURFACE_CREATE ioctl 🎀 that's the whole job. no extra lore, no secret side quests, just a union doing her one iconic task ⭐

💀 reminder bestie: this page is short because the union is short. don't go inventing extra fields, she has exactly rep and req and that's her whole personality 🎀

and that's the tea 🍓 this cutie is filed under ./include/uapi/drm in the Kernel API Manual, dated October 2026 — love that for her, mwah 💋🦋
