STRUCT ACRN_MMIO_DEV_RES(9)

✨ struct acrn_mmio_dev_res(9) ✨

okay bestie, welcome to the Kernel API Manual page for struct acrn_mmio_dev_res(9) — it's giving very specific, very useful resource-description energy, and honestly? iconic. 💅

🌸 NAME 🌸

struct acrn_mmio_dev_res — MMIO device resource description. no cap, that's the whole vibe. 🦋

🎀 SYNOPSIS 🎀

struct acrn_mmio_dev_res {
    __u64 user_vm_pa;
    __u64 service_vm_pa;
    __u64 size;
    __u64 mem_type;
};

💖 Members 💖

• user_vm_pa — Physical address of User VM of the MMIO region for the MMIO device. literally the User VM's physical-address moment. ✨
• service_vm_pa — Physical address of Service VM of the MMIO region for the MMIO device. Service VM gets its own physical-address spot too, periodt. 🫶
• size — Size of the MMIO region for the MMIO device. the "how big is this region" bestie. 🎀
• mem_type — Memory type of the MMIO region for the MMIO device. the memory-type label, slay. 🌸
