STRUCT ACRN_PCIDEV(9)

💅 struct acrn_pcidev(9)

okay bestie, welcome to the kernel API manual for struct acrn_pcidev — it's giving "official docs" but make it cute. this page lives in the Kernel API Manual and it's literally all about Info for assigning or de-assigning a PCI device ✨ no cap, that's the whole vibe.

---

✨ SYNOPSIS ✨

here's the struct in all its glory, copied exactly, no edits, i promise 🫶

struct acrn_pcidev {
    __u32 type;
    __u16 virt_bdf;
    __u16 phys_bdf;
    __u8 intr_line;
    __u8 intr_pin;
    __u32 bar[ACRN_PCI_NUM_BARS];
 };

look at her. iconic. 👑

🎀 Members 🎀

okay so let's meet the cast, member by member:

• type — the Type of the assignment. it's the main character telling you what kind of assignment we're doing 💅
• virt_bdf — Virtual Bus/Device/Function. the virtual side of the BDF situation 🦋
• phys_bdf — Physical Bus/Device/Function. same energy, but the physical one, fr fr 🌸
• intr_line — PCI interrupt line. the literal line the interrupt rides in on ⭐
• intr_pin — PCI interrupt pin. the pin, bestie. the pin 📌
• bar — PCI BARs. that's it, that's the whole description, and honestly? confident. lowkey slay 💀

💖 Description 💖

so here's the tea: this structure will be passed to hypervisor directly. that's the entire description. no extra lore, no secret bonus info. it goes straight to the hypervisor, periodt. 🔥
