STRUCT VIRTIO_RPMSG_CHANNEL(9)

💖 struct virtio_rpmsg_channel(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's a tiny little struct page and it's honestly kind of iconic for how much it does with so little. sit down, hydrate, let's go 🫶

---

✨ NAME ✨

struct virtio_rpmsg_channel — the rpmsg channel descriptor, no cap. that's it, that's the whole vibe check 🎀

---

🌸 SYNOPSIS 🌸

struct virtio_rpmsg_channel {
    struct rpmsg_device rpdev;
    struct virtproc_info *vrp;
 };

look at her. two members. zero notes. the way that struct just sits there being exactly what it needs to be 😭💅

---

🦋 Members 🦋

• rpdev — this is the rpmsg channel device itself, the main character energy of the whole struct, literally the device you're here for 🔥
• vrp — the virtio remote processor device that this channel belongs to, i.e. the struct virtproc_info pointer that tells you which remote proc this channel is riding with 💜

---

🌈 Description 🌈

so here's the tea, bestie: this structure stores the channel that links the rpmsg device to the virtio remote processor device. that's the whole job. it's the little bridge between rpdev and vrp and honestly? she ate. 🍓
