STRUCT HDM_CHANNEL(9)

🦋 struct hdm_channel(9) 🦋

okay bestie, welcome to the Kernel API Manual ✨ this one's a struct, it's private, it's giving backstage-pass energy, and it's literally just here to hold channel-specific data. let's get into it 💅

✨ NAME ✨

struct hdm_channel — the private structure whose whole job is keeping channel specific data 🫶

🌸 SYNOPSIS 🌸

struct hdm_channel {
    char name[sizeof caNNN"];"
    bool is_initialized;
    struct dim_channel ch;
    u16 *reset_dbr_size;
    struct list_head pending_list;
    struct list_head started_list;
    enum most_channel_direction direction;
    enum most_channel_data_type data_type;
 };

ngl that char name[...] line is exactly how it shows up in the page — not me editing it, not me fixing it, we do not touch the source text in this house 💀 character for character, periodt.

💖 Members 💖

• name — the channel name 🏷️ like, its whole identity
• is_initialized — the little identifier that tells you whether the channel is initialized or not 👀 (vibe check: initialized? yes/no)
• ch — HAL specific channel data 🧚 the hardware-abstraction-layer's own stash
• reset_dbr_size — reset DBR data buffer size 📏 that's the size, for the reset DBR data buffer
• pending_list — the list that keeps MBO's before starting transfer 🕐 the waiting room, fr fr
• started_list — the list that keeps MBO's after starting transfer 🔥 the "we're so on" list
• direction — channel direction, which is TX or RX ↔️ pick a lane
• data_type — channel data type 🍓 the flavor of data, basically
