i915_gem_object_has_iomem(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual page for i915_gem_object_has_iomem(9) — yes the name is long, she's iconic like that 💅. This is the function that tells you whether the object is iomem-backed. That's the whole vibe check, fr fr.

✨ SYNOPSIS ✨

bool i915_gem_object_has_iomem (const struct drm_i915_gem_object *obj );

🎀 ARGUMENTS 🎀

• obj — the object to query. You're literally asking this object a question, so be nice to her 🫶.

🦋 DESCRIPTION 🦋

okay so the rule is: only call this while the object is locked or pinned. If you don't, the iomem backing may change under the caller — and that's the warning, no cap 😭.

⚠️ bestie pls respect this: locked or pinned, periodt. Calling it any other way means the iomem backing may change under the caller, and that is not a cute look 💀.

⭐ RETURN ⭐

True if iomem-backed, false otherwise. Simple, clean, slay 💖.
