STRUCT SEV_DATA_INIT(9)

okay so bestie 💖 you’ve landed on struct sev_data_init(9), and yes, that’s the page title — it’s part of the Kernel API Manual. This whole thing is about the INIT command parameters, and it’s lowkey a tiny struct with main-character energy. Let’s get into it ✨

🌸 NAME 🌸

struct sev_data_init — INIT command parameters 💅

✨ SYNOPSIS ✨

       struct sev_data_init {
           u32 flags;
           u32 reserved;
           u64 tmr_address;
           u32 tmr_len;
        };

🎀 Members 🎀

• flags — processing flags 🚩
• tmr_address — system physical address used for SEV-ES 📍
• tmr_len — len of tmr_address 📏

Also, the struct itself has a u32 reserved; field in the synopsis — the Members section doesn’t give reserved its own little description. That’s just how the page is set up, no cap 🫶
