STRUCT LJCA_CLIENT(9)

🌸 NAME 🌸

struct ljca_client — okay bestie, this is the struct that represents a ljca client device, and we’re officially inside the Kernel API Manual. It’s giving kernel-struct realness, and every member below is a little icon that matters. 💖

✨ SYNOPSIS ✨

Here’s the whole shape of it, no cap — copy-paste this energy exactly:

struct ljca_client {
    u8 type;
    u8 id;
    struct list_head link;
    struct auxiliary_device auxdev;
    struct ljca_adapter *adapter;
    void *context;
    ljca_event_cb_t event_cb;
    spinlock_t event_cb_lock;
 };

Lowkey a whole lineup of fields, and each one has lore. 🫶

💅 MEMBERS 💅

• type — the ljca client type. Like, which flavor of ljca client this is. 🍓
• id — the ljca client id within the same client type. Periodt. 🎀
• link — the ljca client on the same ljca adapter. That’s the link energy. 🔥
• auxdev — the auxiliary device object. Cute auxdev representation, literally. 🦋
• adapter — the ljca adapter the ljca client sits on. Home sweet adapter. 🏠
• context — the execution context of the event callback. That’s the vibes the callback runs in. ✨
• event_cb — the callback that the ljca client driver registers to get firmware asynchronous rx buffer pending notifications. Driver signs up here, iykyk. 👑
• event_cb_lock — a spinlock to protect the event callback. Gotta keep the callback safe, no cap. 🔒
