drm_get_format_info(9)

💅 drm_get_format_info(9) 💅

Okay so bestie, welcome to this page from the Kernel API Manual — it's giving “I just need the format info for a framebuffer configuration,” and honestly? Same. 🫶

---

✨ NAME ✨

drm_get_format_info — query information for a given framebuffer configuration. That's the whole vibe, no cap. 🌸

---

🎀 SYNOPSIS 🎀

const struct drm_format_info * drm_get_format_info (struct drm_device
*dev , u32 pixel_format , u64 modifier );

---

🦋 ARGUMENTS 🦋

• dev — the DRM device. Your main-character device energy. 👑
• pixel_format — the pixel format (DRM_FORMAT_*). Literally the format of the pixels, bestie. ✨
• modifier — modifier. That's it. That's the note. 💅

---

🔥 RETURN 🔥

The instance of struct drm_format_info that describes the pixel format, or NULL if the format is unsupported. So like… if it's unsupported, you get NULL, and that's the whole answer. 😭
