radeon_fence...e_completion(9)

📦 version 7.3.1, in nixpkgs unstable

💖 radeon_fence_driver_force_completion — from the Kernel API Manual bestie 💖

okay so this is a kernel API manual page, and no cap it's kind of a dramatic one — it's the "everything is on fire, get the waiters out" function. let's get into it 🫶

🌸 NAME 🌸

radeon_fence_driver_force_completion — force all fence waiter to complete

like literally all of them. every sad little process waiting on a fence gets to stop waiting. periodt 💅

✨ SYNOPSIS ✨

void radeon_fence_driver_force_completion (struct radeon_device *rdev ,
       int ring );

returns void btw, so don't go looking for a return value, there isn't one 🎀

🦋 ARGUMENTS 🦋

  • rdev — radeon device pointer. it's the radeon device, and it's a pointer, iykyk 💜
  • ring — the ring to complete. literally the thing you're forcing to completion, one ring, that's the vibe ✨

🔥 DESCRIPTION 🔥

okay so hear me out, this one is basically the emergency exit 🌈

In case of GPU reset failure make sure no process keep waiting on fence that will never complete.

that's it, that's the whole thing. if the GPU reset goes sideways and a fence genuinely is never, ever going to complete, you do not leave processes hanging on it forever — this is the function that makes sure nobody's stuck waiting on a fence that will never complete. it's giving cleanup crew energy, it's giving "we tried, it failed, let everybody go home" 😭

lowkey a warning, highkey important: this exists because the GPU reset failed. it's the fallback, not the flex. the fence it's completing is one that will never complete on its own — that's the whole reason this function is here fr fr 💀

okay that's the page bestie 🧚 this whole thing comes from ./drivers/gpu/drm/radeon, and it's dated October 2026 — so yeah, mark your calendar, or don't, it's a manual page not a birthday 🎂 mwah, go read the fence code, ily, bye 💖🎀💅
