STRUCT SEV_DATA_SNP_PAGE_UNSMASH(9)

✨ struct sev_data_snp_page_unsmash(9) ✨

okay so bestie, welcome to the section-9 kernel API manual page for struct sev_data_snp_page_unsmash 💅 this is the lil params struct for the SNP_PAGE_UNSMASH command, and yes it's giving "one field but make it iconic" 🎀

---

🌸 NAME 🌸

struct sev_data_snp_page_unsmash — literally the params for the SNP_PAGE_UNSMASH command, no cap 🫶

---

⭐ SYNOPSIS ⭐

struct sev_data_snp_page_unsmash {
    u64 paddr;
};

that's it. that's the whole struct. main character energy tbh 👑

---

💖 MEMBERS 💖

• paddr — the system physical address of the page you wanna unsmash, fr fr. plot twist: the 0th bit in the address is the page-size indicator 🕵️‍♀️ 0h means a 4 KB page, and 1h means a 2 MB page. so like, the low bit is doing double duty as a vibe check on your page size 💀
