zynqmp_disp..._find_format(9)

✨ zynqmp_disp_layer_find_format — kernel api manual energy ✨

okay bestie, so this is a Kernel API Manual page for zynqmp_disp..._find_format(9) and it's genuinely giving "i know where all the formats live" 💅 buckle up 🎀

---

🌸 NAME 🌸

zynqmp_disp_layer_find_format — literally the function that finds the format info for a DRM format. that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

const struct zynqmp_disp_format * zynqmp_disp_layer_find_format (struct
zynqmp_disp_layer *layer , u32 drm_fmt );

like, it takes a layer and a format and hands you back a const struct zynqmp_disp_format *, no biggie 🫶

---

🎀 ARGUMENTS 🎀

• layer — the layer 💖 that's the thing you're searching inside, periodt.
• drm_fmt — the DRM format you want to search for 🔍 the whole reason we're here.

---

💫 DESCRIPTION 💫

so what it does is: it searches the display subsystem's format information that corresponds to the DRM format drm_fmt you passed in — for that specific layer — and then it returns a pointer to the format descriptor. that's it, that's the function, and honestly? iconic. 🌈

---

⭐ RETURN ⭐

• a pointer to the format descriptor if it's found 👑
• NULL otherwise 💀 (no cap, sometimes the format just isn't there)

💀 quick vibe check: the return can legit be NULL, so pls check it before you dereference, bestie. no cap, that's how people get got.
