🌸 NAME 🌸

okay so bestie, this is the xe_guc_klv_count(9) page, straight outta the Kernel API Manual ✨. It does exactly one iconic thing: count KLVs present in the buffer 💅. That's the whole main-character job, no cap 🎀.

✨ SYNOPSIS ✨

int xe_guc_klv_count (const u32 *klvs , u32 num_dwords );

the way this signature pulls up looking all official 😭🫶

🫶 ARGUMENTS 🫶

• klvs — the buffer with KLVs, periodt. This is the thing you're handing over, bestie 💖.
• num_dwords — number of dwords (u32) in the buffer. yes, dwords, and yes, u32 units 🔢✨.

---

🔥 RETURN 🔥

it's giving two possible outcomes, bestie:

• the number of recognized KLVs 👑
• or a negative error code if the KLV buffer is truncated 😭💀

so if things are cute, you get a count; if the buffer got cut off, you get that negative error code instead. periodt 🫶
