STRUCT VFIO_CCW_PARENT(9)

💜 struct vfio_ccw_parent(9) 💜

okay so bestie, welcome to the manual page for struct vfio_ccw_parent — that's the kernel API one, from the Kernel API Manual, and we're literally about to break it all down together 🫶

✨ NAME ✨

struct vfio_ccw_parent — no cap, that's the whole name section. The original just gives you the struct name and nothing else, so we're vibing with that 🌸

🎀 SYNOPSIS 🎀

here's the struct in all its glory, copy-pasted exactly because we do not mess with code:

struct vfio_ccw_parent {
    struct device           dev;
    struct mdev_parent      parent;
    struct mdev_type        mdev_type;
    struct mdev_type        *mdev_types;
 };

like… look at it. it's giving "I contain multitudes" 💅

👑 Members 👑

• dev — an embedded device struct. it's literally built into the struct, not a pointer, not a mystery, just cozy embedded device energy ✨
• parent — the parent data structures for the mdevs created. yes bestie, the mdevs (that's mediated devices, iykyk) 🦋
• mdev_type — identifying information for mdevs created. it's the little name tag at the party 🎀
• mdev_types — this one's a pointer to struct mdev_type (note the *, we love a pointer era). it lands under the same description as above in the original — identifying information for the mdevs created — so that's exactly what we're telling you, fr fr 💖

quick heads-up: in the original, mdev_types doesn't get its own separate description — it shares the "identifying information for mdevs created" wording that follows the parent line. so don't come for me, I'm just being faithful 💀

and that's the whole page, no crumbs left 🍓 this iconic little slice of kernel API manual came from ./drivers/s390/cio and it's dated October 2026 — so yes, it's from the future, she's ahead of her time 💅✨ slay 💜
