💅 i915_vma_pin_fence — a Kernel API Manual moment

okay so bestie, welcome to the i915_vma_pin_fence(9) page 💖 this is from the Kernel API Manual and it's lowkey iconic, so let's get into it ✨

🌸 NAME 🌸

i915_vma_pin_fence — pin fencing state 🎀

✨ SYNOPSIS ✨

int i915_vma_pin_fence (struct i915_vma *vma );

🦋 ARGUMENTS 🦋

  • vma — the vma you're pinning fencing for, like that's her job now 💅

💜 DESCRIPTION 💜

So what this does is it pins the fencing state — and yes that means whether it's tiled or untiled, both count 🫶 — to make sure the vma (and its object, can't forget the object, they're a package deal fr fr) is ready to be used as a scanout target. main character energy only 🌟

⚠️ but listen, the fencing status must be synchronized first by calling i915_vma_get_fence — don't skip this step bestie, it's giving prerequisites 😭

And then the resulting fence pin reference must be released again with i915_vma_unpin_fence. like, you can't just leave it pinned, that's not the vibe 🙈

👑 RETURN 👑

True if the vma has a fence, false otherwise. simple as that, no cap 💀
