💅 drm_gpuvm_interval_empty — the kernel API manual, bestie edition

okay so real talk, this one's a little function from the kernel API manual that answers exactly one (1) question: is this chunk of the VA space, like… empty? That's it. That's the whole gig. And honestly? Iconic.

✨ NAME ✨

drm_gpuvm_interval_empty — tells you whether a given interval of the VA space is empty 🫧

🌸 SYNOPSIS 🌸

bool drm_gpuvm_interval_empty (struct drm_gpuvm *gpuvm , u64 addr , u64 range );

🎀 ARGUMENTS 🎀

  • gpuvm — the drm_gpuvm you're checking the range for, like, this is the whole vibe we're inspecting 💖
  • addr — the start address of the range, aka where the bit you care about begins
  • range — the range of the interval, so like how far it goes from there 🌈

⭐ RETURN ⭐

true if the interval is empty, and false otherwise. no cap, that's the whole answer 🫶
