STRUCT GB_CAMERA(9)

💖 struct gb_camera(9) 💖

okay bestie, so this is a page from the Kernel API Manual — yes, the kernel has its own manual, and yes it's iconic. today's main character is struct gb_camera, which is literally A Greybus Camera Device. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

like, here's the whole struct, character for character, no cap:

struct gb_camera {
    struct gb_bundle *bundle;
    struct gb_connection *connection;
    struct gb_connection *data_connection;
    u16 data_cport_id;
    struct mutex mutex;
    enum gb_camera_state state;
    struct {
      struct dentry *root;
      struct gb_camera_debugfs_buffer *buffers;
    } debugfs;
    struct gb_camera_module module;
 };

🌸 Members 🌸

okay so let's meet the squad, one field at a time 🫶

• connection — the greybus connection for camera management. this is the one that handles the talking, the admin of it all 💅
• data_connection — the greybus connection for camera data. this one's the actual content pipeline, the one doing the real work 🔥
• data_cport_id — the data CPort ID on the module side. lowkey just an ID, but it's the ID, bestie 🦋
• mutex — protects the connection and state fields. do not touch those fields without it, fr fr, that's its whole job 👑
• state — the current module state. it's giving "how are we doing today" but for the camera 🌈
• debugfs — debugfs entries for camera protocol operations testing. yep, that's the little nested struct up there with root and buffers inside it 🧚
• module — Greybus camera module registered to HOST processor. big main character energy, honestly ⭐

ngl, bundle is chilling in the struct too — it's right there in the synopsis, and we didn't make it up. the Members list just doesn't give it a lil description, so I'm not gonna invent one for it 💀
