🌸 amdgpu_fence_wait_empty — it's giving "wait for the vibes to settle" ✨

Ok so bestie, real talk: this is amdgpu_fence_wait_empty(9) from the Kernel API Manual, and it's literally just the "hey, are we done yet??" function of the AMDGPU fence world 💅

✨ NAME ✨

amdgpu_fence_wait_empty — wait for all fences to signal 🎀

No cap, that's the whole vibe. You sit there, you wait, and eventually the fences all signal and you can go about your day 🦋

💫 SYNOPSIS 💫

int amdgpu_fence_wait_empty (struct amdgpu_ring *ring );

That's it, that's the whole signature. One arg, one int coming back at you 🫶

🎯 ARGUMENTS 🎯

  • ring — the ring index the fence is associated with. Like, which ring are we talking about, bestie? It's a struct amdgpu_ring *, so it's the actual ring, and it's the one whose fences we're gonna wait on 💖

🔥 DESCRIPTION 🔥

So what does it actually do? It waits for all fences on the requested ring to signal (all asics). Every single asic, no exceptions, we're not playing favourites 💀

Returns 0 if the fences have passed — slay, we're done ✅ — and an error for all other cases. Like, anything that isn't "yay the fences passed" is an error, periodt. Not me being dramatic, that's just literally what it says 🙈

Ngl, "error for all other cases" is doing a lot of heavy lifting in that sentence, but that's the deal: 0 = good, everything else = not good. Vibe check failed, basically 😭
