xe_hw_fence_alloc(9)

✨ xe_hw_fence_alloc(9) ✨

okay so bestie, you found the Kernel API Manual page for xe_hw_fence_alloc 💅 and honestly? it's a little one. a tiny little guy. but we're gonna give it the full main character treatment anyway 🎀

---

🌸 NAME 🌸

xe_hw_fence_alloc — literally just allocate an hw fence. that's the whole vibe 🦋

---

⭐ SYNOPSIS ⭐

struct dma_fence * xe_hw_fence_alloc (void );

like, it returns a struct dma_fence * and takes void. no notes. slay 💖

---

🧚 ARGUMENTS 🧚

• void — no arguments, bestie. none. zero. the function said "i need nothing from you" and honestly? iconic 👑

---

🌈 DESCRIPTION 🌈

so what it does is: it allocates an hw fence. that's it. that's the post 💅

but — and this is the important part, don't skip it — it does not initialize it. allocate, yes. initialize, absolutely not. that's somebody else's job (xe_hw_fence_init(9), we see you 👀). so you get a fence, but it's giving blank canvas, not ready-to-go. no cap 🫶

---

🔥 RETURN 🔥

you get back a pointer to the allocated fence, OR a negative error pointer if something went wrong 😭 so like, vibe check your return value before you use it, fr fr 💀

and that's the page!! written down in ./drivers/gpu/drm/xe and dated October 2026 — so go forth, allocate responsibly, and remember: allocated ≠ initialized 🍓🧚💜
