STRUCT AMDXDNA_HWCTX_PARAM_CONFIG_CU(9)

💜 NAME 💜

struct amdxdna_hwctx_param_config_cu — the literal configuration blueprint for CUs inside a hardware context. Like, this struct is the vibe check for telling your hardware context which CUs it's working with. No cap.

(also hi bestie, this is from the Kernel API Manual — welcome to the section 9 group chat 🫶)

---

✨ SYNOPSIS ✨

okay so here's the whole shape of it, bestie, copy it exactly:

struct amdxdna_hwctx_param_config_cu {
    __u16 num_cus;
    __u16 pad[3];
    struct amdxdna_cu_config cu_configs[];
};

It's giving "small struct, big responsibilities" honestly 👑

---

🎀 Members 🎀

• num_cus — the count of CUs you're configuring. Literally just how many we're talking about here, bestie. Count them. Carefully. 💅
• pad — MBZ. and yes that means Must Be Zero, so put zeros in there, don't be quirky about it 🙈
• cu_configs — the flex of this struct: a whole array of CU configurations, and each one is a struct amdxdna_cu_config. Iconic. It's a flexible array member living its best main character life at the end of the struct 🦋

bestie note: pad is MBZ — must be zero. Not "probably zero". Not "zero-ish". Zero. I'm not being dramatic, that's just the rule 💀

okay that's the whole page, go forth and configure those CUs 💖 this came out of ./include/uapi/drm, dated October 2026, and the page itself is struct amdxdna_hwctx_param_config_cu(9) from the Kernel API Manual — mwah, slay, periodt 🧚‍♀️🌸
