STRUCT SDW_ENABLE_CH(9)

🎀 struct sdw_enable_ch(9) 🎀

okay so bestie, gather round, because this is the struct sdw_enable_ch(9) page from the Kernel API Manual and it's literally the little struct that turns a Data Port channel on and off. tiny struct, big main character energy 💅

---

✨ NAME ✨

struct sdw_enable_ch — Enable/disable Data Port channel 🎛️

Like, that's it. That's the whole job. It's giving "small but mighty."

---

🌸 SYNOPSIS 🌸

struct sdw_enable_ch {
    unsigned int port_num;
    unsigned int ch_mask;
    bool enable;
};

no cap, that's the entire shape of it 🫶

🦋 Members 🦋

• port_num — Port number 🔢 — which port we're talking about, bestie.
• ch_mask — Active channel mask 🎚️ — the mask for the channels that are actually active.
• enable — Enable (true) /disable (false) channel ⚡ — literally the on/off switch. true means on, false means off. iconic behavior.
