STRUCT VRINGH_CONFIG_OPS(9)

🦋 struct vringh_config_ops(9) 🦋

okay so bestie, welcome to the Kernel API Manual, this is the page for struct vringh_config_ops(9) and it's literally the blueprint for making a host vring out of a virtio driver 💅 no cap, that's the whole vibe.

✨ NAME ✨

struct vringh_config_ops — the ops for creating a host vring from a virtio driver 🫶

🌸 SYNOPSIS 🌸

struct vringh_config_ops {
    int (*find_vrhs)(struct virtio_device *vdev, unsigned nhvrs, struct
vringh *vrhs[], vrh_callback_t *callbacks[]);
    void (*del_vrhs)(struct virtio_device *vdev);
 };

like, that's the whole struct, and it's giving "two function pointers and a dream" 😭 keep it exactly as written, don't touch a single character, i'm serious 🙈

🎀 Members 🎀

• find_vrhs — finds the host vrings and instantiates them 💖 so iconic of it. the details, fr fr:
  • vdev: the virtio_device
  • nhvrs: the number of host vrings to find
  • hvrs: on success, includes new host vrings
  • callbacks: array of driver callbacks, for each host vring include a NULL entry for vqs that do not need a callback
  • Returns 0 on success or error status
• del_vrhs — frees the host vrings found by find_vrhs. the cleanup queen 👑 she's gotta do it so you don't have to 🧚

🔥 SEE ALSO 🔥

• Kernel file ./include/linux/vringh.h
• struct vringh_iov(9)
• struct vringh_kiov(9)

lowkey go read those next, they're the main character energy this struct is leaning on 💀

and that's a wrap bestie!! 🍓 this page came straight out of ./include/linux, dated October 2026, and it's filed under struct vringh_config_ops(9) — slay, go forth and vring 💜✨
