STRUCT SEV_DATA_SNP_ACTIVATE(9)

💖 NAME 💖

struct sev_data_snp_activate — the param bundle for the SNP_ACTIVATE command 🎀 (and yes bestie, it's a Kernel API Manual situation, this is the deep kernel lore)

✨ SYNOPSIS ✨

okay so here's literally the whole shape of it, no cap:

struct sev_data_snp_activate {
    u64 gctx_paddr;
    u32 asid;
 };

that's it. two members. tiny struct, big main character energy 💅

🦋 Members 🦋

• gctx_paddr — the system physical address of the guest context page 📍 like, the actual physical one, not a virtual vibe
• asid — the ASID that gets bound to the guest 🔗 that's the thing it does, it binds it, periodt

and if you wanna see where this little icon actually lives, it's chillin' in the kernel file ./include/linux/psp-sev.h 📁 go say hi 🫶

ok that's the whole page bestie, you ate that 💖 and like always: the source of truth is the kernel tree at ./include/linux, snagged back in October 2026 — so go touch grass or go read the kernel, either way slay 💅✨🌸
