✨ xe_guc_buf_gpu_addr ✨

okay so bestie, welcome to the kernel API manual for xe_guc_buf_gpu_addr — this is a section 9 page from the Kernel API Manual, and honestly? it's a whole little vibe. it's short, it's sweet, it does exactly one thing, and it does it slayfully 💅

🌸 NAME 🌸

xe_guc_buf_gpu_addr — bestie, this one just obtains a GPU address of the sub-allocation. that's it. that's the whole personality. iconic behavior honestly 🎀

---

🦋 SYNOPSIS 🦋

u64 xe_guc_buf_gpu_addr (const struct xe_guc_buf buf );

yes that's the entire signature, no cap — it hands you back a u64, and it takes a const struct xe_guc_buf named buf. clean. minimal. main character energy ✨

---

🍓 ARGUMENTS 🍓

• buf — the xe_guc_buf to query 💖 like, this is the thing you're asking about, girl. you hand it over and it's gonna tell you where it lives on the GPU.

---

🔥 RETURN 🔥

it returns a GPU address of the sub-allocation. periodt. no complicated multi-value situation, no -errno dramatics described here — just the address, straight up 🫶

ngl this page is tiny but that doesn't mean you skip the details, okay? a GPU address is a GPU address, and you need it 🌈
