STRUCT OOBMSM_PLAT_INFO(9)

✨ struct oobmsm_plat_info(9) ✨

okay bestie, so this is a page from the Kernel API Manual — we're talking about struct oobmsm_plat_info, and it's literally the little info card that holds all the platform tea for a device instance 🫶

---

🌸 NAME 🌸

struct oobmsm_plat_info — platform information for a device instance 💅

---

🎀 SYNOPSIS 🎀

struct oobmsm_plat_info {
    u16 cdie_mask;
    u8 package_id;
    u8 partition;
    u8 segment;
    u8 bus_number;
    u8 device_number;
    u8 function_number;
 };

yes the extra space before the closing brace is canon, don't come for me 🙈 it's copied exactly, iykyk

💖 Members 💖

• cdie_mask — the mask of all the compute dies in the partition 👑 like, every single one, accounted for
• package_id — the CPU Package id, a.k.a. which package this bad boy belongs to
• partition — the package partition id, and it comes into play when there are multiple VSEC PCI devices per package 🦋 so if that's your situation, this field is the main character
• segment — the PCI segment ID ✨
• bus_number — the PCI bus number 🌈
• device_number — the PCI device number 💜
• function_number — the PCI function number ⭐

---

🧚 Description 🧚

so basically this struct's whole job is to store platform data for an OOBMSM device instance 🎀 that's it, that's the vibe — it's the container, the little basket of PCI-and-partition facts, no cap 💅
