💅 drm_format_info_is_yuv_sampling_444 💅

okay bestie, welcome to the Kernel API Manual — yes, that's the whole manual, and yes, this page is a (9) section page, so it's that kind of party 🎀. This one is short, sweet, and honestly kind of iconic — it's a lil vibe check for your pixel formats. Let's get into it ✨

✨ NAME ✨

drm_format_info_is_yuv_sampling_444 — check that the format info matches a YUV format with 4:4:4 sub-sampling 🦋

---

🌸 SYNOPSIS 🌸

bool drm_format_info_is_yuv_sampling_444 (const struct drm_format_info
*info );

---

🎀 ARGUMENTS 🎀

• info — format info. literally just the format info, that's the whole thing, that's the assignment 💅

---

⭐ RETURN ⭐

A boolean indicating whether the format info matches a YUV format with 4:4:4 sub-sampling. so it's a yes-or-no situation, no in-between, no "it's complicated" — true if it's giving 4:4:4 YUV, false if it's not 🫶
