STRUCT MC_SUBLED(9)

💖 struct mc_subled(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for struct mc_subled — it’s giving “tiny but mighty color-component glow-up” ✨ and we’re gonna read it together, no cap.

✨ NAME ✨

struct mc_subled — Color component description. 💅

🦋 SYNOPSIS 🦋

       struct mc_subled {
           unsigned int color_index;
           unsigned int brightness;
           unsigned int intensity;
           unsigned int max_intensity;
           unsigned int channel;
        };

👑 Members 👑

• color_index — Color ID. 🎨
• brightness — Scaled intensity. ⚖️
• intensity — Current intensity. ⚡
• max_intensity — Maximum supported intensity value. 🚦
• channel — Channel index. 🔢

🌸 Description 🌸

okay so this struct literally describes a color component of a multicolor LED. 🌈 Many multicolor LEDs do not support global brightness control in hardware, so they use the brightness field together with led_mc_calc_color_components to perform the intensity scaling in software. Such drivers should set max_intensity to 0 to signal the multicolor LED core that the maximum global brightness of the LED class device should be used for limiting incoming intensity values. 💅

Multicolor LEDs that do support global brightness control in hardware should instead set max_intensity to the maximum intensity value supported by the hardware for a given color component. No cap. 👑
