i915_gem_fence_size(9)

💖 NAME 💖

okay bestie, welcome to i915_gem_fence_size(9) from the Kernel API Manual — the manual name is literally right there in the group chat. This function is all about the required global GTT size for a fence, periodt.

✨ SYNOPSIS ✨

bestie, the signature is giving exactly this:

       u32 i915_gem_fence_size (struct drm_i915_private *i915 , u32 size ,
       unsigned int tiling , unsigned int stride );

🦋 ARGUMENTS 🦋

• i915 — i915 device. Yep, the i915 device itself, the main character of this call.
• size — object size. The size of the object, no cap.
• tiling — tiling mode. Which tiling mode we're rolling with.
• stride — tiling stride. The tiling stride value, iykyk.

🌸 DESCRIPTION 🌸

okay so here's the tea: it returns the required global GTT size for a fence — that's the view of a tiled object — and it takes into account potential fence register mapping. That's the whole function, bestie, and it's lowkey iconic ✨.
