💖 amdgpu_fence_enable_signaling(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — yes, the Kernel API Manual, the one we all pretend to read. today's main character is amdgpu_fence_enable_signaling, and she is lowkey iconic. let's get into it 🎀

🌸 NAME 🌸

amdgpu_fence_enable_signaling — literally just enabling signalling on a fence, that's the whole vibe 💅

✨ SYNOPSIS ✨

bool amdgpu_fence_enable_signaling (struct dma_fence *f );

that's it. that's the signature. she returns a bool and takes one pointer, no cap 🫶

🦋 ARGUMENTS 🦋

  • f — the fence. that's it, that's the argument. it's a fence. a struct dma_fence * to be precise, but honestly "fence" covers it. slay 💜

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this function gets called with the fence_queue lock held. like, that's a given, not something you do, it's the situation you walk into. main character energy fr fr 😭

while it's in there, it adds a callback to fence_queue. and what does that callback do? so glad you asked 🧚:

  • it checks if this fence is signaled
  • and if it is? it signals the fence ✅
  • and then it removes itself — self-cleaning king behavior, we love a function that knows when to leave the party 👑

periodt. that's the whole function. it checks, it signals, it dips 🌈

⭐ SEE ALSO ⭐

the kernel file she lives in, because of course:

  • ./drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c

and the whole friend group — her entire fence-adjacent squad 🫶:

like, that is a list. go read them, iykyk 📚💅

real talk bestie: this all lives under ./drivers/gpu/drm/amd/amdgpu, version dated October 2026, and the page you're reading is amdgpu_fenc...le_signaling(9) from the Kernel API Manual — yes the title got abbreviated and yes she still ate 💖✨🎀 go forth and signal those fences 🦋🌸
