UNION DRM_VMW_ALLOC_BO_ARG(9)

💅 union drm_vmw_alloc_bo_arg(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ — and specifically the page for union drm_vmw_alloc_bo_arg. yes that's the whole thing. it's a union. it's in the kernel. she's booked, she's busy, she's iconic 💖

---

🌸 NAME 🌸

union drm_vmw_alloc_bo_arg — and ngl the description slot on this one is literally empty 😭 the manpage said "no thoughts, head empty" and honestly? respect. so the name is all we got. it's a union named drm_vmw_alloc_bo_arg. periodt 🎀

---

✨ SYNOPSIS ✨

here's her whole little outfit — two members, no more, no less:

union drm_vmw_alloc_bo_arg {
    struct drm_vmw_alloc_bo_req req;
    struct drm_vmw_bo_rep rep;
 };

that's it. that's the girl. a union with two structs inside, iykyk 🦋

---

👑 Members 👑

lowkey the shortest cast list ever but we love them both:

• req — the input data, as described above. that's the "what you're asking for" side of the situation 💅
• rep — the output data, as described above. that's the "what you get back" side 🫶

---

💀 Description 💀

so what is this actually for? she is the argument to the DRM_VMW_ALLOC_BO Ioctl. that's the whole description, fr fr — no extra lore, no side quests, no deleted scenes. she exists to be handed to that one ioctl and that's her main character energy ⭐

twenty-five siblings and every one of them ate 🔥 go read them, they're all in ./include/uapi/drm 💜

a lil reminder bestie: don't go guessing at fields that aren't listed here — req is input, rep is output, and the ioctl is DRM_VMW_ALLOC_BO. that's the tea, don't add to it 🍓

and that's the page!! 🎀 sign-off time: this one's from ./include/uapi/drm, dated October 2026, and it's union drm_vmw_alloc_bo_arg(9) — mwah, go be a well-adjusted little ioctl argument, we're all rooting for you 💖✨🦋
