STRUCT SEV_DATA_SNP_DOWNLOAD_FIRMWARE(9)

🌸 NAME 🌸

okay so bestie, welcome to the Kernel API Manual (section 9, we're fancy here) ✨ — this page is all about struct sev_data_snp_download_firmware, aka the params for the SNP_DOWNLOAD_FIRMWARE command 💅

Literally it's the little bundle of info the kernel hands over when it wants firmware downloaded. That's the whole vibe. 🦋

---

🎀 SYNOPSIS 🎀

the way it's just two fields and yet it's doing so much 😭

struct sev_data_snp_download_firmware {
    u64 address;
    u32 len;
};

---

💜 Members 💜

like, here's the whole cast, both of them, main character energy only 👑

• address — the physical address of the firmware image 🫶 yes, physical, not virtual, don't come for me
• len — the length of the firmware image 📏 that's how big the thing is

---

🔥 SEE ALSO 🔥

okay this list is genuinely iconic, it's the whole SEV extended family reunion and everyone showed up 🌈

it all lives in the kernel file ./include/linux/psp-sev.h — go say hi 💖
