STRUCT SEV_DATA_SNP_DBG(9)

🎀 struct sev_data_snp_dbg(9) 🎀

okay bestie, so this is from the Kernel API Manual — welcome to the kernel side of the group chat 💅 we're doing the struct sev_data_snp_dbg page today and honestly? it's lowkey iconic.

---

✨ NAME ✨

struct sev_data_snp_dbg — the parameter struct for the DBG_ENCRYPT/DBG_DECRYPT command, no cap 🔥

---

🦋 SYNOPSIS 🦋

here's the whole vibe, literally the entire struct:

struct sev_data_snp_dbg {
    u64 gctx_paddr;
    u64 src_addr;
    u64 dst_addr;
 };

three u64s. that's it. she's minimal, she's clean, she's giving main character energy 😌

---

🌸 Members 🌸

gctx_paddr

the system physical address of the guest context page 🫶 that's the whole thing.

src_addr

the source address of the data you're operating on — like, where the data lives before anything happens to it ✨

dst_addr

the destination address of the data you're operating on — where it's headed, iykyk 💖
