intel_forma...v_semiplanar(9)

💅 NAME 💅

intel_format_info_is_yuv_semiplanar — the vibe-check function that tells you whether the format you're holding is a YUV semiplanar situation or not, bestie. Yes this is from the Kernel API Manual, no I will not stop talking about it.

---

✨ SYNOPSIS ✨

bool intel_format_info_is_yuv_semiplanar (const struct drm_format_info
*info , u64 modifier );

That's it. That's the whole entrance. A bool walks in, two arguments in hand, and everyone in the group chat wants to know the answer. 💖

---

🌸 ARGUMENTS 🌸

• info — the format you want checked, okay? Like, the actual format info struct. Hand it over, she's got this. 🫶
• modifier — the modifier being used with that format. They come as a pair, they're literally a matching set, you don't split them up. 👑

---

🔥 RETURN 🔥

It gives you back true when the info / modifier combo is YUV semiplanar. That's the whole answer. true means yes, icon. ⭐

No cap, it's a bool, so it's giving "yes or no" and nothing else. Don't go looking for extra lore in the return value, there isn't any. 💀

Okay that's the whole page, you ate that. 💅✨ This little beauty ships out of ./drivers/gpu/drm/i915/display, dated October 2026, and it's part of the Kernel API Manual. Go check your formats, bestie, I believe in you. 🎀🌈💜
