DRM_MODE_INIT(9)

💅 DRM_MODE_INIT 💅

ok so bestie, we're in the Kernel API Manual today (yes, the Kernel API Manual, we're fancy now ✨) and the page we're reading is literally called DRM_MODE_INIT(9). She's a macro. She's iconic. Let's get into it 🎀

---

🌸 NAME 🌸

DRM_MODE_INIT — Initialize display mode 🖥️✨

---

🦋 SYNOPSIS 🦋

DRM_MODE_INIT (hz , hd , vd , hd_mm , vd_mm );

that's the whole vibe, no cap 💅

---

💖 ARGUMENTS 💖

okay so she takes five things, and every single one of them matters, so like… pay attention bestie 🙈

• hz — the Vertical refresh rate in Hertz. yes, the vertical one. the refresh-y one. ⚡
• hd — Horizontal resolution, width. so like, how wide she is. 📏
• vd — Vertical resolution, height. and how tall. 📐
• hd_mm — Display width in millimeters. that's the physical width, not the pixel width — don't mix them up, i'm begging 😭
• vd_mm — Display height in millimeters. physical height, same deal 🫶

---

✨ DESCRIPTION ✨

so this macro? she initializes a drm_display_mode — and that struct is literally the main character 👑 — with all the info about refresh rate, resolution, and physical size. like, she's giving you the full picture: how fast it refreshes, how many pixels, and how big the screen actually is in real life millimeters. no guessing, no vibes-only, actual numbers. slay 💅🔥
