STRUCT VMW_BINDING_INFO(9)

💅 struct vmw_binding_info(9) 💅

okay bestie, so this is a page from the Kernel API Manual and it's literally all about struct vmw_binding_info — aka the per binding type information for the binding manager. yes the title is fancy, we're keeping it, and the manual name is Kernel API Manual in case you were wondering 🎀

---

✨ NAME ✨

struct vmw_binding_info — the per-binding-type info stash for the binding manager. it's giving "lookup table energy" and honestly? iconic.

---

✨ SYNOPSIS ✨

struct vmw_binding_info {
    size_t size;
    const size_t *offsets;
    vmw_scrub_func scrub_func;
 };

that's the whole struct, no cap. three members and they all pull their weight 🫶

---

✨ Members ✨

• size — the size of the struct binding that's derived from a struct vmw_ctx_bindinfo. literally just how big the thing is 💖
• offsets — an array[shader_slot] of offsets pointing at the array[slot] of struct bindings for this binding type. yes it's arrays all the way down, we love a nested situation 🌸
• scrub_func — a pointer to the scrub function for this binding type. it scrubs. it's the scrubber. that's the vibe 🧚

---

✨ Description ✨

so this struct holds static information — that's its whole job — and that static info helps optimize the binding manager and avoid an excessive amount of switch statements 😭 like bestie, we are NOT doing a million switch cases at runtime, that's not the move. we look it up in the table and we slay 💅

lowkey the entire point is: static info in, excessive switch statements out. main character design decision fr fr.
