cvs_csi_get_mbus_config(9)

📦 version 7.3.1, in nixpkgs unstable

💅 cvs_csi_get_mbus_config(9) — like, the CSI-2 bus config page bestie

okay so this is from the Kernel API Manual, and it's literally called cvs_csi_get_mbus_config ✨ — no cap, that's the whole name.

🎀 NAME 🎀

cvs_csi_get_mbus_config — provides the current CSI-2 bus configuration. That's it, that's the gig. 💖

🦋 SYNOPSIS 🦋

int cvs_csi_get_mbus_config (struct v4l2_subdev *sd , unsigned int pad ,
struct v4l2_mbus_config *cfg );

like… it takes three things and gives you back an int. iconic behavior tbh 🫶

🌸 ARGUMENTS 🌸

  • sd — the sub-device. your main character struct 💅
  • pad — the pad index. yes bestie, the index, not the pad itself 🙈
  • cfg — the returned bus config. this one's an output, so it comes back filled in ✨

👑 DESCRIPTION 👑

So what does it actually do? It:

  • fills in the lane ordering and the number of lanes 🔥
  • retrieves the link frequency from the remote entity 🌈

that's the whole vibe check, fr fr 💜

⭐ RETURN ⭐

Returns 0 on success, or a negative errno if it's not giving 😭
