STRUCT ES58X_OPERATORS(9)

💅 struct es58x_operators(9) 💅

okay bestie, you're in the Kernel API Manual and this is the page for struct es58x_operators(9) — the little squad of function pointers that handle encoding/decoding the TX/RX messages. no cap, it's giving “pluggable device behavior” energy. 🦋

✨ NAME ✨

struct es58x_operators — function pointers used to encode/decode the TX/RX messages. periodt. 💖

🎀 SYNOPSIS 🎀

struct es58x_operators {
    u16 (*get_msg_len)(const union es58x_urb_cmd *urb_cmd);
    int (*handle_urb_cmd)(struct es58x_device *es58x_dev, const union
es58x_urb_cmd *urb_cmd);
    void (*fill_urb_header)(union es58x_urb_cmd *urb_cmd, u8 cmd_type,
u8 cmd_id, u8 channel_idx, u16 cmd_len);
    int (*tx_can_msg)(struct es58x_priv *priv, const struct sk_buff
*skb);
    int (*enable_channel)(struct es58x_priv *priv);
    int (*disable_channel)(struct es58x_priv *priv);
    int (*reset_device)(struct es58x_device *es58x_dev);
    int (*get_timestamp)(struct es58x_device *es58x_dev);
 };

• get_msg_len — grabs the msg_len field of the urb_cmd. The offset of msg_len inside urb_cmd depends of the device model. iykyk, it's per-device behavior. 🌸
• handle_urb_cmd — decodes the URB command received from the device and dispatches it to the relevant sub function. main character energy for incoming messages fr fr. 👑
• fill_urb_header — fills the header of urb_cmd. cute little header moment. 🎀
• tx_can_msg — encodes a TX CAN message and adds it to the bulk buffer cmd_buf of es58x_dev. slay, get that message queued. 🔥
• enable_channel — starts the CAN channel. go bestie go. ✨
• disable_channel — stops the CAN channel. okay bye channel. 💅
• reset_device — full reset of the device. N.B: this feature is only present on the ES581.4. For ES58X FD devices, this field is set to NULL. very important, don't forget the NULL vibe. 😭
• get_timestamp — requests a timestamp from the ES58X device. time check, but make it kernel. ⭐
