✨ intel_memory_region_reserve(9) ✨

okay so bestie, this one's from the Kernel API Manual and honestly it's giving "small function, big responsibility" 💅 it lives in the i915 DRM driver and its whole thing is reserving a chunk of a memory region. let's get into it 🫶

🌸 NAME 🌸

intel_memory_region_reserve — Reserve a memory range 🔥

---

🎀 SYNOPSIS 🎀

int intel_memory_region_reserve (struct intel_memory_region *mem ,

💖 ARGUMENTS 💖

• mem — The region for which we want to reserve a range. like, which memory region are we doing this to, bestie? 👑
• offset — Start of the range to reserve. where the range begins, no cap 📍
• size — The size of the range to reserve. how much we're grabbing, periodt 📏

0 on success, negative error code on failure. so if you get 0 you're slaying ✨, and if it's negative… yeah that's a vibe check you failed 😭
