STRUCT SEV_DATA_LAUNCH_MEASURE(9)

💅 NAME 💅

okay so bestie, this is the Kernel API Manual page for struct sev_data_launch_measure(9), and it's literally the parameters for the LAUNCH_MEASURE command. that's the whole vibe 🎀

struct sev_data_launch_measure — LAUNCH_MEASURE command parameters.

✨ SYNOPSIS ✨

struct sev_data_launch_measure {
    u32 handle;
    u32 reserved;
    u64 address;
    u32 len;
};

🌸 Members 🌸

here's the cast, no cap 🫶

• handle — handle of the VM to process. it's giving "which VM are we doing this for" 💅
• address — physical address containing the measurement blob. yes, physical address, bestie, not the vibe-address 🌈
• len — len of measurement blob. literally the len of the measurement blob, periodt ✨

also, u32 reserved; is up in the struct too — the manpage doesn't give it a Members description, so I'm not gonna invent lore. silent side character energy 💀
