xe_range_fence_insert(9)

💅 xe_range_fence_insert(9) — from the Kernel API Manual, bestie

okay so quick vibe check on the name: this whole page is about xe_range_fence_insert — the "range fence insert" girlie. That's it, that's the function. She inserts. She's a range fence. Iconic behavior honestly. ✨

---

🌸 SYNOPSIS 🌸

int xe_range_fence_insert (struct xe_range_fence_tree *tree , struct
xe_range_fence *rfence , const struct xe_range_fence_ops *ops , u64
start , u64 last , struct dma_fence *fence );

no cap, that's the whole signature — six args, one int return, and she's ready to go 🫶

---

💖 ARGUMENTS 💖

here's the cast of characters, one by one, no skips:

• tree — the range fence tree you're inserting intoi. yes. "intoi." that's literally what the page says, i'm not fixing it, she's perfect the way she is 😭
• rfence — the range fence. the main character of this whole operation fr fr.
• ops — the range fence ops. the ops!! the operations!!
• start — start address of the range fence 📍
• last — last address of the range fence 🎯 (note: last, not end. respect the name.)
• fence — a dma fence, and this one's got a job: it signals that the range fence can be removed and freed. the cleanup queen. she literally eats and deletes. 🔥

---

⭐ RETURN ⭐

• 0 on success ✨
• non-zero on failure 💀

that's the entire return story, bestie — zero is good, anything else means something went sideways.

• xe_range_fence_tree_next(9)

like… it's giving full range-fence-tree cinematic universe 🌈 iykyk

lowkey a reminder: the free-and-remove of that range fence is tied to the dma_fence signalling — that's the entire point of the fence argument, so don't sleep on it 🙈
