STRUCT RPROC_VRING(9)

💖 struct rproc_vring(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's all about struct rproc_vring, aka the remoteproc vring state. it's giving "small struct, big responsibilities" and honestly? we're obsessed. 🎀

---

✨ NAME ✨

struct rproc_vring — the remoteproc vring state, fr fr 💅

---

🦋 SYNOPSIS 🦋

struct rproc_vring {
    void *va;
    int num;
    u32 da;
    u32 align;
    int notifyid;
    struct rproc_vdev *rvdev;
    struct virtqueue *vq;
 };

like, that's the whole struct. not me memorizing it. 😭

🌸 Members 🌸

• va — the virtual address. that's it, that's the vibe. ✨
• num — the vring size. how many. the count. the number. 🔢
• da — the device address. yes it's a u32, no we're not discussing it. 💜
• align — the vring alignment. everything gotta line up, periodt. 📐
• notifyid — the rproc-specific unique vring index. unique!! iconic behavior honestly. 👑
• rvdev — the remote vdev. it's the parent-ish situation. 🫶
• vq — the virtqueue of this vring. the actual queue doing the actual work. main character energy tbh. 🔥

and that's the whole page, bestie!! 💖 this little number lives in ./include/linux, it's from the October 2026 era, and it's filed under struct rproc_vring(9). slay, go read some remoteproc code, ily 🫶✨🌸💅
