STRUCT SEV_USER_DATA_PDH_CERT_EXPORT(9)

✨ struct sev_user_data_pdh_cert_export(9) ✨

okay so bestie, this is a page straight out of the Kernel API Manual — like, the actual kernel docs, not a vibe. buckle up 🫶

---

🌸 NAME 🌸

struct sev_user_data_pdh_cert_export — the params for the PDH_CERT_EXPORT command 💅

---

🦋 SYNOPSIS 🦋

here's the whole struct, copied exactly, no cap:

struct sev_user_data_pdh_cert_export {
    __u64 pdh_cert_address;
    __u32 pdh_cert_len;
    __u64 cert_chain_address;
    __u32 cert_chain_len;
 };

that's it. that's the struct. she's cute, she's compact, she's giving "i hold command parameters and i know it" ✨

---

🎀 Members 🎀

• cert_chain_address — this one's the PDH certificate chain itself. the address. where the chain lives. iconic 👑
• cert_chain_len — and this is the length of that PDH certificate chain. how long it is. the way that a chain needs a length, honestly 💀

real talk: those are the only two members the page spells out, so those are the only two i'm spelling out. the other two fields are in the struct up there and i'm not out here inventing lore 🙈

• struct sev_user_data_get_id(9)
• struct sev_user_data_get_id2(9)

they're all linked, they all matter, go read them, iykyk 📚✨

and that's the page!! mwah 💋 before you go — this one lives in ./include/uapi/linux and it's dated October 2026, and the header on top is struct sev_u..._cert_export(9) (yes it's truncated with the dots in the original, that's not me being lazy, that's literally the title 🌈). slay, go export some certs, bye bestie 🧚💖
