✨ radeon_fence_enable_signaling(9) ✨

okay so this is a page from the Kernel API Manual, and bestie, it's a little one but it's lowkey important 💅 — it's all about radeon_fence_enable_signaling, and we're gonna get you comfy with it in like two minutes, fr fr.

🌸 NAME 🌸

radeon_fence_enable_signaling — literally just enable signalling on fence, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

bool radeon_fence_enable_signaling (struct dma_fence *f );

that's it, that's the whole signature, she's sleek 👑

💖 ARGUMENTS 💖

  • f — the fence. yeah. the fence itself. the main character of this whole situation 🫶

🔥 DESCRIPTION 🔥

okay so picture this: this function gets called while the fence_queue lock is already held — like, you don't grab the lock yourself, it's already in your hand, do NOT go grabbing it again 💀 — and what it does is it adds a callback to fence_queue.

and that callback? it checks if this fence is signaled, and if it is, it signals the fence and then removes itself. self-cleaning icon behavior honestly. ate and left no crumbs ✨🧹

ngl the lock-held part is the whole tea here — that's a precondition, not a suggestion, so respect it 🙈

🌈 SEE ALSO 🌈

this list is long long, so buckle up bestie, we're going through all of them 💅

the kernel file lives right here: ./drivers/gpu/drm/radeon/radeon_fence.c

and then the whole friend group:

and that's the whole page, bestie, you're officially fenced-in and fluent 💜 this little cutie came out of ./drivers/gpu/drm/radeon back in October 2026 — same title, same (9) energy, we just gave her a glow-up 🌟 slay, go read some kernel code 🧚‍♀️⭐
