💖 radeon_fence_wait(9) 💖

okay so bestie, welcome to the Kernel API Manual page for radeon_fence_wait(9) — like, the actual kernel documentation, but make it make sense. this one is short and sweet, so let's go 🌸

✨ NAME ✨

radeon_fence_wait — the function that just sits there and waits for a fence to signal 🫶 like literally it waits. that's the whole gig.

🌈 SYNOPSIS 🌈

int radeon_fence_wait (struct radeon_fence *fence , bool intr );

yes mamas, that's the whole signature — two args, one int coming back at you 💅

🎀 ARGUMENTS 🎀

  • fence — a radeon fence object. that's the thing you're waiting on, okay? the main character of this function fr fr.
  • intr — use interruptible sleep. it's a bool, so it's a yes/no vibe check: true means interruptible, false means non-interruptible. iykyk.

🔥 DESCRIPTION 🔥

so what does it do? it waits for the requested fence to signal — and yes, on all asics babes, every single one, no exceptions 💜

the intr argument is the little switch that decides your sleeping situation while you wait for that fence:

  • true → interruptable sleep 😴✨ (something can come interrupt your nap)
  • false → non-interruptable sleep 💀 (you are SLEEPING, do not perceive, do not disturb)

and the return value? here's the tea:

  • it returns 0 if the fence has passed ✅
  • it returns an error for all other cases 😭 like every single other case, no in-between
ngl bestie that's the entire description — no hidden lore, no extra side quests. it waits, it returns 0 or an error, periodt. 👑

the kernel file lives right here, go look:

and the whole fence friend group 🫶 — these are all the siblings:

like, that's a whole family reunion and radeon_fence_wait is invited to all of it 💅✨

okay that's the page!! 💖 this gem comes out of ./drivers/gpu/drm/radeon, dated October 2026, and it's filed under radeon_fence_wait(9) — go forth and wait on those fences, bestie, you're gonna slay 🎀⭐
