💖 radeon_fence_wait_empty(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a little function from the radeon DRM crew, and honestly? it's giving "waiting room" energy. it just sits there until all the fences on a ring have signalled. no cap.

🎀 NAME 🎀

radeon_fence_wait_empty — wait for all fences to signal 💅

✨ SYNOPSIS ✨

int radeon_fence_wait_empty (struct radeon_device *rdev , int ring );

like, that's the whole signature. short and iconic 🌸

🦋 ARGUMENTS 🦋

  • rdev — the radeon device pointer. your main character device, basically 👑
  • ring — the ring index that the fence is associated with. which ring are we talking about, bestie? this one. ⭐

💜 DESCRIPTION 💜

So this function waits for all the fences on the requested ring to signal — and yes, that's all asics, no exceptions, everybody's invited 🫶

Returns 0 if the fences have passed. Returns an error for all other cases. that's it, that's the whole vibe check 😭

⚠️ ok important one: the caller must hold ring lock. fr fr. do not skip this. this is not the moment to be casual, bestie 💀
