i915_gem_get_tiling_ioctl(9)

💅 i915_gem_get_tiling_ioctl ✨

okay so bestie, welcome to the i915_gem_get_tiling_ioctl(9) page — yeah it's a mouthful, iykyk 😭. This one lives in the Kernel API Manual, and it's literally the little ioctl handler that tells you what tiling mode your object is rocking. Let's get into it 🎀

---

🌸 NAME 🌸

i915_gem_get_tiling_ioctl — the IOCTL handler that gets the tiling mode. no cap, that's the whole vibe check 🦋

---

✨ SYNOPSIS ✨

int i915_gem_get_tiling_ioctl (struct drm_device *dev , void *data ,
       struct drm_file *file );

like, here's the exact signature, character for character, don't @ me 💅

---

🫶 ARGUMENTS 🫶

• dev — the DRM device. main character energy, obviously 👑
• data — the data pointer for the ioctl. it's giving "payload delivery" 📦
• file — the DRM file for the ioctl call. yes bestie, that file 🌈

---

💖 DESCRIPTION 💖

So what does it actually do? It returns the current tiling mode and the required bit 6 swizzling for the object. that's it, that's the whole thing, and honestly? iconic ⭐

and yeah — it's called by the user via ioctl. so this is the handler sitting there waiting for userspace to come ask 🧚

---

🔥 RETURN 🔥

• Zero on success 🎉
• negative errno on failure 😭 (yes, negative, keep that in mind fr fr)
