✨ drm_client_modeset_probe(9) ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — yes we're reading kernel docs together, this is our era now, and honestly? it's giving main character energy. sit down, grab a strawberry beverage 🍓, and let's get into it.

---

🌸 NAME 🌸

drm_client_modeset_probe — the "hey, what displays do we even have?" probe function 💅

---

🦋 SYNOPSIS 🦋

int drm_client_modeset_probe (struct drm_client_dev *client , unsigned
       int width , unsigned int height );

literally just three args and a return value. no cap, that's it. 🫶

---

✨ ARGUMENTS ✨

• client — your DRM client, the whole reason we're here 💖
• width — maximum display mode width. it's optional, so like, no pressure bestie 🙈
• height — maximum display mode height. also optional, also no pressure 🌈

---

💜 DESCRIPTION 💜

so what does this icon actually do? it sets up display pipelines for the enabled connectors, and then it stores the resulting config in the client's modeset array. that's the whole vibe. connectors in, config out, iconic behaviour 👑

ngl, that's the entire description. sometimes the docs are short and sweet and we respect that.

---

🔥 RETURN 🔥

• 0 — slay, success ✨
• negative error code — not slay, failure 😭
