STRUCT OMNIA_LED(9)

🌈 struct omnia_led(9) — the per-LED glow-up 💅

okay so bestie, this is a page from the Kernel API Manual (the 9 section, for all you kernel-curious girlies) and it's all about struct omnia_led — literally the per-LED part of a driver's private data structure. it's giving "backstage pass to your LEDs" ✨

---

🌸 NAME 🌸

struct omnia_led — the per-LED slice of the driver's private data structure. like, every LED gets its own lil vibe folder 🎀

---

✨ SYNOPSIS ✨

here's the whole struct, exactly as it lives, no notes:

struct omnia_led {
    struct led_classdev_mc mc_cdev;
    struct mc_subled subled_info[OMNIA_LED_NUM_CHANNELS];
    u8 cached_channels[OMNIA_LED_NUM_CHANNELS];
    bool on, hwtrig;
    int reg;
 };

(that last brace is indented one space in the original and honestly? we respect the choices 💅)

🦋 Members 🦋

okay so let's meet the cast, one member at a time:

• mc_cdev — the multi-color LED class device. this is the main character of the struct ngl 👑
• subled_info — per-channel information. one entry for each channel, holding all its lil details 🍓
• cached_channels — cached values of per-channel brightness that was sent to the MCU. yes bestie, we keep receipts of what we told the microcontroller 💀
• on — whether the LED was set on. on or off, iconic either way 🔥
• hwtrig — whether the LED blinking was offloaded to the MCU. hardware handles it, so you don't have to, periodt ✨
• reg — the LED identifier to the MCU. it's literally the LED's name-tag when it talks to the MCU 🎀

• struct omnia_leds(9)

like, go read the actual driver file and then its big sibling struct — iykyk 🫶

lowkey a reminder: these struct members are described exactly as the manual says, no extra lore added, fr fr 🙈
