STRUCT VDPA_MGMTDEV_OPS(9)

💅 struct vdpa_mgmtdev_ops — vdpa device ops ✨

okay bestie, welcome to the struct vdpa_mgmtdev_ops page from the Kernel API Manual, section 9 🎀 — this is the ops table you fill in when you're the management-device girlie running the whole vdpa show. no cap, it's short and it slays.

🌸 NAME 🌸

struct vdpa_mgmtdev_ops — literally vdpa device ops. that's the whole vibe. 💖

---

✨ SYNOPSIS ✨

here's the struct, in all its glory — don't touch the types, they're iconic:

struct vdpa_mgmtdev_ops {
    int (*dev_add)(struct vdpa_mgmt_dev *mdev, const char *name, const struct vdpa_dev_set_config *config);
    void (*dev_del)(struct vdpa_mgmt_dev *mdev, struct vdpa_device *dev);
    int (*dev_set_attr)(struct vdpa_mgmt_dev *mdev, struct vdpa_device *dev, const struct vdpa_dev_set_config *config);
};

three function pointers. that's it. three. and honestly? each one is doing main character energy in its own little lane. 🫶

🦋 Members 🦋

• dev_add — Add a vdpa device using alloc and register 😌 so you're out here allocating it AND registering it, both, in one callback. efficient queen behavior fr fr.
• dev_del — Remove a vdpa device using unregister 💀 the breakup callback — unregister that device, let it go, block the number.
• dev_set_attr — change a vdpa device's attr after it was create 🌈 the post-makeover glow-up hook: the device already exists and you still get to tweak its attrs. (yes, the original says "create" — we're keeping it, it's cute, lowkey iykyk.)

warning bestie: these are your callbacks — the kernel is gonna call them, so if you leave one doing something unhinged, that's on you, not on me 🙈
