STRUCT VIRTIO_JACK(9)

💖 struct virtio_jack(9) 💖

okay so bestie, welcome to the struct virtio_jack page — that's section 9 of the Kernel API Manual, and yes she's a whole struct from the VirtIO world. VirtIO jack. That's the vibe. Let's get into it 🎀

✨ NAME ✨

struct virtio_jack — literally the VirtIO jack. that's the whole name. iconic, concise, no notes 💅

🌸 SYNOPSIS 🌸

struct virtio_jack {
    struct snd_jack *jack;
    u32 nid;
    u32 features;
    u32 defconf;
    u32 caps;
    bool connected;
    int type;
 };

look at her. seven fields, all accounted for, not one of them skipped. we love a complete struct 🫶

🦋 Members 🦋

• jack — the kernel jack control. this is the actual struct snd_jack * doing the work, main character energy fr fr.
• nid — the functional group node identifier. a u32, obviously. it knows which group it belongs to 😌
• features — the jack virtio feature bit map, written as 1 << VIRTIO_SND_JACK_F_XXX. that's the bit-map situation, exactly like that, no cap.
• defconf — the pin default configuration value. a u32. that's it, that's the field.
• caps — the pin capabilities value. also a u32. slay.
• connected — the current jack connection status. it's a bool, so like… true or false, plugged or not plugged, that whole storyline 💀
• type — the kernel jack type, written SND_JACK_XXX. an int, and the type system is doing its thing ✨

okay bestie that's the whole page 💖 it lives in ./sound/virtio, it's dated October 2026, and it's filed under struct virtio_jack(9). go off, you understood the assignment 🎀✨🦋
