xe_guc_klv_encode_object(9)

🎀 xe_guc_klv_encode_object(9) 🎀

okay bestie, welcome to the Kernel API Manual entry for xe_guc_klv_encode_object — it's giving “tiny helper, very important job” energy, and we're gonna read it together 💅✨

---

🌸 NAME 🌸

xe_guc_klv_encode_object — encodes an object using a custom encoder as a single KLV. periodt. 🦋

---

✨ SYNOPSIS ✨

u32 * xe_guc_klv_encode_object (u32 *klvs , u32 avail , u16 key , const
void *obj , u32 *(*encoder)(u32 *klvs, u32 avail, const void *obj) );

---

💖 ARGUMENTS 💖

• klvs — the buffer where to place the KLV. that's its whole moment, let it have it 🫶
• avail — number of dwords (u32) available in the buffer. like, how much room do we actually have, bestie 😭
• key — the key to be used. yes ma'am, the key 🔑
• obj — opaque object pointer. mysterious. iconic. no further questions 💀
• encoder — function pointer to the custom encoder. this is the main character function pointer, lowkey 👑

---

🔥 RETURN 🔥

on success, you get a pointer to the buffer location past the encoded KLV — slay 💅

but if there was no space to encode the KLV, you get an ERR_PTR instead. no space = no KLV, and that's the vibe check 🚫✨
