ENUM VMW_SM_TYPE(9)

💅 enum vmw_sm_type(9) — or, "what can this graphics context actually DO" 🎀

okay so picture this: you're deep in the Kernel API Manual (yes, that one, the Linux kernel docs, we're fancy now ✨) and you stumble on enum vmw_sm_type. Bestie. Buckle up, because this little enum is literally just a ✨vibe check✨ for graphics hardware — it tells you which shader-model capabilities a device can support. That's it. That's the whole thing. And honestly? Iconic. 👑

🌸 NAME 🌸

enum vmw_sm_type — Graphics context capability supported by device.</p> 🫶

Basically: a menu of "how much shader-model can your GPU handle, queen?" and the driver picks the highest one that applies.

---

✨ SYNOPSIS ✨

enum vmw_sm_type {
    VMW_SM_LEGACY ,
    VMW_SM_4 ,
    VMW_SM_4_1 ,
    VMW_SM_5 ,
    VMW_SM_5_1X ,
    VMW_SM_MAX

};

no cap, that's the whole shape of it — a ladder from "old school" all the way up to VMW_SM_MAX. 🪜

---

🦋 Constants 🦋

okay so here's each one, in order, exactly as listed — every single one gets its moment 💅

• VMW_SM_LEGACY — the pre-DX context era. Baby's first context, if you will. 😭
• VMW_SM_4 — context support up to SM4. We stan a solid mid-tier queen.
• VMW_SM_4_1 — context support up to SM4_1. tiny upgrade, big slay.
• VMW_SM_5 — context support up to SM5. now we're cooking 🔥
• VMW_SM_5_1X — adds support for sm5_1 and gl43 extensions. she's got extras, she's main character energy fr fr 👑
• VMW_SM_MAX — should be the last. that's literally the whole job description. keep her at the end or the vibe check breaks 🫶
