drm_format_...s_yuv_planar(9)

💜 drm_format_info_is_yuv_planar — the "is this a three-plane YUV baddie?" check

okay so picture this, you're deep in the Kernel API Manual (that's the manual name btw, slay) and you need to know if some format info is giving planar YUV energy. that's literally the whole job of this function. it's a vibe check for pixel formats 🎀

---

✨ SYNOPSIS ✨

bool drm_format_info_is_yuv_planar (const struct drm_format_info *info
);

it returns a bool, bestie. a simple yes-or-no. no drama, no side effects, no cap 💅

---

🌸 ARGUMENTS 🌸

• info — the format info you're interrogating. that's it. that's the whole argument. one (1) single format info struct, and she's const so nobody's touching her ✨

---

🦋 RETURN 🦋

it hands you back a boolean indicating whether the format info matches a planar YUV format — like, YUV with the data laid out in three separate planes, one for each YUV component. three planes, three components, one iconic little bool 💖

so to be crystal clear: true = yes queen, three planes, one per YUV component. false = not that. we move on 🫶
