dma_fence_end_signalling(9)

💅 dma_fence_end_signalling (9) — Kernel API Manual

okay so bestie, welcome to the kernel API manual, this one's a little one but she's important 🎀

---

✨ NAME ✨

dma_fence_end_signalling — end a critical DMA fence signalling section

no cap, that's the whole vibe: you're closing out a critical section. periodt 💅

---

🌸 SYNOPSIS 🌸

void dma_fence_end_signalling (bool cookie );

---

🦋 ARGUMENTS 🦋

• cookie — the opaque cookie you got back from dma_fence_begin_signalling. it's giving "receipt for your vibes" — you hand it back and everything matches up 🍓

---

💖 DESCRIPTION 💖

she closes a critical section annotation that was opened by dma_fence_begin_signalling. that's it, that's the whole function. open with one, close with the other, keep the annotation balanced or the whole thing is lowkey cursed 😭

think of it like the } to your {, bestie — the matching piece that tells everyone the critical section is done 🫶

🧚 friendly reminder from your local kernel bestie: this pairs with dma_fence_begin_signalling(9). don't leave a section hanging, that's not the move 🙈
