STRUCT ACRN_CSTATE_DATA(9)

💖 NAME 💖

okay so bestie, welcome to the struct acrn_cstate_data(9) page in the Kernel API Manual — yes, that manual. This struct is literally a C state package defined in ACPI. It's giving "let's describe a C state package" energy, and honestly? Iconic. ✨

✨ SYNOPSIS ✨

Here's the whole vibe, exactly as written:

struct acrn_cstate_data {
    struct acrn_acpi_generic_address        cx_reg;
    __u8 type;
    __u32 latency;
    __u64 power;
};

No cap, that's the complete struct. 🫶

🎀 Members 🎀

• cx_reg — Register of the C state object. That's the field, bestie. 🎀
• type — Type of the C state object. Yep, the type of the C state object. 💅
• latency — The worst-case latency to enter and exit this C state. Important detail, keep it. 😭
• power — The average power consumption when in this C state. Also important. 🔥
