STRUCT SEV_DATA_PDH_CERT_EXPORT(9)

💅 struct sev_data_pdh_cert_export(9) 💅

okay bestie, so this is a page from the Kernel API Manual, and it's all about one little struct: struct sev_data_pdh_cert_export. It's giving "backstage pass to the PDH_CERT_EXPORT command" energy, and honestly? iconic. Let's get into it 🫶

---

✨ NAME ✨

struct sev_data_pdh_cert_export — the parameters for the PDH_CERT_EXPORT command. that's the whole vibe, no cap.

---

🦋 SYNOPSIS 🦋

here's the struct in all her main-character glory, copied exactly so you know I'm not playing with you:

struct sev_data_pdh_cert_export {
    u64 pdh_cert_address;
    u32 pdh_cert_len;
    u32 reserved;
    u64 cert_chain_address;
    u32 cert_chain_len;
 };

like… look at her. five fields. lowkey flawless 💖

---

🎀 Members 🎀

okay so the manual only spells out two of the fields, and I'm not about to make stuff up about the rest (that's not the vibe, fr fr). so:

• cert_chain_address — the PDH certificate chain. yes bestie, the address of it. that's what the page says, and I'm just the messenger 🧚
• cert_chain_len — the length of the PDH certificate chain. the manual literally says "len of PDH certificate chain," so we're keeping it cute and keeping it exact ✨

the other fields (pdh_cert_address, pdh_cert_len, reserved) are chillin' up in the struct too — they're right there in the synopsis, no erasure happening. the page just doesn't give them their own little blurbs. iykyk 💅
