STRUCT SDW_MASTER_RUNTIME(9)

✨ NAME ✨

struct sdw_master_runtime — runtime stream parameters for Master 💅

Okay so this is the struct sdw_master_runtime(9) page from the Kernel API Manual, and it's literally the glow-up cheat sheet for the Master's runtime stream parameters. Slay. 🎀

🦋 SYNOPSIS 🦋

struct sdw_master_runtime {
    struct sdw_bus *bus;
    struct sdw_stream_runtime *stream;
    enum sdw_data_direction direction;
    unsigned int ch_count;
    struct list_head slave_rt_list;
    struct list_head port_list;
    struct list_head stream_node;
    struct list_head bus_node;
 };

🎀 Members 🎀

• bus — the Bus handle, fr fr. 🚌
• stream — the Stream runtime handle. main character energy for the stream side of things. 🌊
• direction — the Data direction for Master. which way the data is going, bestie. 🧭
• ch_count — Number of channels handled by the Master for this stream; can be zero. yep, zero is valid, no cap. 🔢
• slave_rt_list — the Slave runtime list. iconic little list energy. 👑
• port_list — List of Master Ports configured for this stream; can be zero. again, zero is allowed, okay? 🚪
• stream_node — sdw_stream_runtime master_list node. it's giving linked-list node realness. 🔗
• bus_node — sdw_bus m_rt_list node. same vibe, different list. 🧚
