STRUCT MEDIA_DEVNODE(9)

💖 NAME 💖

struct media_devnode — the Media device node, bestie 💅 like this is literally the struct that holds the whole media-devnode situation together ✨

🦋 SYNOPSIS 🦋

okay so here's the whole thing, no edits, no cap:

struct media_devnode {
    struct media_device *media_dev;
    const struct media_file_operations *fops;
    struct device dev;
    struct cdev cdev;
    struct device *parent;
    int minor;
    unsigned long flags;
    void (*release)(struct media_devnode *devnode);
 };

🌸 Members 🌸

• media_dev — pointer to struct media_device 💖
• fops — pointer to struct media_file_operations holding the media device ops, iykyk
• dev — pointer to struct device that contains the media controller device 🎀
• cdev — the struct cdev pointer, aka the character device
• parent — the parent device 👑
• minor — the device node minor number, fr fr
• flags — the flags, and they're a combination of the MEDIA_FLAG_* constants 🌈
• release — release callback, and it gets called at the very end of the media_devnode_release routine in media-device.c ⭐

✨ Description ✨

So this structure represents a media-related device node. That's the whole vibe 🦋

The parent is a physical device — and lowkey this part matters: it must be set by core or device drivers before registering the node 🙈 like it's not optional, it's giving prerequisite, periodt.
