dma_resv_iter_next_unlocked(9)

✨ dma_resv_iter_next_unlocked(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a function page, and yes it's a whole vibe.

---

🎀 NAME 🎀

dma_resv_iter_next_unlocked — get the next fence in an unlocked dma_resv obj. literally that's the whole thing, no cap 💖

---

🌸 SYNOPSIS 🌸

struct dma_fence * dma_resv_iter_next_unlocked (struct dma_resv_iter
*cursor );

look at that signature bestie, it's giving "one pointer in, one pointer out" 🦋

---

⭐ ARGUMENTS ⭐

• cursor — the cursor you're holding, like, the one that's currently sitting at the current position 📍 that's it, that's the arg.

---

🔥 DESCRIPTION 🔥

okay so this returns the next fence from an unlocked dma_resv obj. simple, right? but listen 👀

⚠️ Beware — the iterator can be restarted. so if your code is out here accumulating statistics or doing anything ~similar~, you have to check for that with dma_resv_iter_is_restarted. no cap, don't sleep on this one 😭

and for that exact reason, the manpage is like: prefer the locked dma_resv_iter_next whenever possible. like, whenever. it's right there. use it. 💅

so yeah — next fence from an unlocked dma_resv obj, but mind the restart, bestie 🫶
