STRUCT VIRTIO_SND_MSG(9)

💖 struct virtio_snd_msg(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this is the whole entire glow-up of struct virtio_snd_msg, aka the Control message. that's it, that's the name. she's a control message. main character energy fr fr 👑

🎀 SYNOPSIS 🎀

struct virtio_snd_msg {
    struct scatterlist sg_request;
    struct scatterlist sg_response;
    struct list_head list;
    struct completion notify;
    refcount_t ref_count;
 };

like, copy that exactly, don't @ me 💅

🌸 Members 🌸

• sg_request — the scattergather list holding a device request (the header). it's giving "here's what I want from you" 🫶
• sg_response — the scattergather list holding a device response (the status). the comeback. the reply. the receipts 💀
• list — pending message list entry. she's literally in the queue, waiting her turn, lowkey iconic 🦋
• notify — request completed notification. the "we're done here bestie" ping ✨
• ref_count — reference count used to manage a message lifetime. keep track of her, don't let her ghost you, no cap 👑
