UNION VMW_VIEW_DESTROY(9)

💅 union vmw_view_destroy(9)

okay bestie, so this is a page from the Kernel API Manual — yes the actual kernel API manual, welcome to the group chat 🎀 — and it's all about union vmw_view_destroy. It's literally just the command body for destroying a view. Short king of a struct, but iconic. ✨

---

🌸 NAME 🌸

union vmw_view_destroy — the view destruction command body, no cap 🫶

---

⭐ SYNOPSIS ⭐

union vmw_view_destroy {
    struct SVGA3dCmdDXDestroyRenderTargetView rtv;
    struct SVGA3dCmdDXDestroyShaderResourceView srv;
    struct SVGA3dCmdDXDestroyDepthStencilView dsv;
    struct SVGA3dCmdDXDestroyUAView uav;
    u32 view_id;
 };

---

🦋 Members 🦋

• rtv — the RenderTarget view destruction command body 🎀
• srv — the ShaderResource view destruction command body 🌸
• dsv — the DepthStencil view destruction command body 💜
• view_id — a single u32 view id. just one. that's the whole thing. 💅

---

✨ Description ✨

so here's the vibe check on this union 🧚 the assumption in play is that all the union members are really represented by a single u32 in the command stream. like, every one of them — that's the whole bit.

but listen — if that's not the case, the size of this union will not equal the size of a u32, and then the assumption is straight-up invalid. ⚠️

and the slay part? we detect that at compile time in the vmw_so_build_asserts function. not at runtime, not at 3am when you're debugging — at compile time. obsessed. 🔥
