STRUCT ACRN_IOREQ_NOTIFY(9)

✨ struct acrn_ioreq_notify(9) ✨

Okay bestie, gather round 💖 this is a page from the Kernel API Manual, and it's literally all about one little struct: struct acrn_ioreq_notify. It's not a function, it's not a syscall, it's a vibe — the actual shape of an ioreq completion notification. 🎀

🌸 NAME 🌸

struct acrn_ioreq_notify — the structure of ioreq completion notification. That's it, that's the whole assignment. 💅

🦋 SYNOPSIS 🦋

Here's the whole thing, no cap, copy it exactly:

struct acrn_ioreq_notify {
    __u16 vmid;
    __u16 reserved;
    __u32 vcpu;
 };

Lowkey adorable how small it is, right? Three fields. Three. Main character energy in a tiny package. 👑

💜 Members 💜

• vmid — the User VM ID 🫶 like, which VM are we even talking about, bestie?
• reserved — reserved, and it should be 0 ✨ don't be quirky, don't put a 5 in there, just leave it at 0 fr fr 🙈
• vcpu — the vCPU ID 🌈 the specific virtual CPU in question, iykyk
