ENUM V4L2_MBUS_FRAME_DESC_TYPE(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 enum v4l2_mbus_frame_desc_type(9) 🌸

okay bestie, this is a page from the Kernel API Manual, and it's honestly such a tiny icon — it's just an enum that tells you what kind of media bus a frame description is talking about. Like, it's giving "hello, which bus are you" energy. Let's get into it 💅

✨ NAME ✨

enum v4l2_mbus_frame_desc_type — the media bus frame description type, aka the little label that says what kind of bus we're on 🦋

✨ SYNOPSIS ✨

enum v4l2_mbus_frame_desc_type {
    V4L2_MBUS_FRAME_DESC_TYPE_UNDEFINED ,
    V4L2_MBUS_FRAME_DESC_TYPE_PARALLEL ,
    V4L2_MBUS_FRAME_DESC_TYPE_CSI2

};

like, that's the whole vibe. three constants, no cap 🎀

✨ Constants ✨

  • V4L2_MBUS_FRAME_DESC_TYPE_UNDEFINED — the undefined frame desc type, aka the "we don't know her" option 😭. Drivers should not use this one — nope, not even a little — it's purely there for backwards compatibility. It's legacy energy, don't touch it 🫶
  • V4L2_MBUS_FRAME_DESC_TYPE_PARALLEL — parallel media bus. that's it, that's the whole thing ✨
  • V4L2_MBUS_FRAME_DESC_TYPE_CSI2 — CSI-2 media bus 🌈. Important: the frame desc parameters must be set in struct v4l2_mbus_frame_desc_entry->csi2. Like, that's where they live, periodt 📍
this is the one your driver actually cares about — if you're on CSI-2, put your params in struct v4l2_mbus_frame_desc_entry->csi2 and nowhere else, iykyk 💀

✨ SEE ALSO ✨

first up, there's a kernel file you should look at:

  • Kernel file ./include/media/v4l2-subdev.h

and then the whole friend group of related symbols (it's a lot, bestie, but they're all iconic 👑):

that's the whole page, bestie — go forth and describe your frames correctly 💖✨

mwah 💋 this one came from the source path ./include/media, and the date on it is October 2026 — so yeah, she's from the future, main character energy fr fr 👑🦋
