STRUCT DRM_VMW_GB_SURFACE_CREATE_REP(9)

💅 struct drm_vmw_gb_surface_create_rep(9) — Kernel API Manual

okay so bestie, welcome to the glow-up era of the vmwgfx uapi headers ✨ this one lives in the Kernel API Manual and honestly? it's giving "quiet little struct that does a lot behind the scenes" energy. let's get into it 🫶

---

🌸 NAME 🌸

struct drm_vmw_gb_surface_create_rep — and that's literally it, the NAME section is out here with zero elaboration, main character silence 💀 (the real tea is all in Members and Description, keep scrolling)

---

🎀 SYNOPSIS 🎀

struct drm_vmw_gb_surface_create_rep {
    __u32 handle;
    __u32 backup_size;
    __u32 buffer_handle;
    __u32 buffer_size;
    __u64 buffer_map_handle;
 };

look at her. five fields. not one wasted byte. iconic 👑

🦋 Members 🦋

• handle — the surface handle. that's her name tag at the party 💅
• backup_size — size of the backup buffers for this surface. like, how much room the understudy gets 🎭
• buffer_handle — handle of the backup buffer. it's SVGA3D_INVALID_ID if there isn't one — so if you see that value, no buffer, don't go looking 😌
• buffer_size — the actual size of the buffer identified by buffer_handle. real measurements only, no cap 📏
• buffer_map_handle — offset into device address space for the buffer identified by buffer_handle. iykyk, it's the map coordinates for that buffer 🗺️

---

🌈 Description 🌈

so here's the vibe check 🔥 this struct is part of the output argument for the DRM_VMW_GB_SURFACE_REF ioctl. and it's also the output argument for the DRM_VMW_GB_SURFACE_CREATE ioctl. versatile queen, she does both 💖
