STRUCT SEV_DATA_LAUNCH_SECRET(9)

✨ NAME ✨

struct sev_data_launch_secret — LAUNCH_SECRET command parameters. This is the Kernel API Manual page for struct sev_data_launch_secret(9), and bestie it is literally all about those LAUNCH_SECRET command parameters. 💖

🦋 SYNOPSIS 🦋

okay so here’s the struct in all its structured glory — keep it exactly like this, no cap:

struct sev_data_launch_secret {
    u32 handle;
    u32 reserved1;
    u64 hdr_address;
    u32 hdr_len;
    u32 reserved2;
    u64 guest_address;
    u32 guest_len;
    u32 reserved3;
    u64 trans_address;
    u32 trans_len;
 };

💅 Members 💅

• handle — handle of the VM to process
• hdr_address — physical address containing the packet header
• hdr_len — len of packet header
• guest_address — system physical address of guest memory region
• guest_len — len of guest_paddr
• trans_address — physical address of transport memory buffer
• trans_len — len of transport memory buffer

also the synopsis has reserved1, reserved2, and reserved3 holding their spots, and this page doesn’t give them separate member blurbs — leaving them exactly as-is, periodt. 🫶
