STRUCT PCI_EPC_BAR_RSVD_REGION(9)

🎀 struct pci_epc_bar_rsvd_region — Kernel API Manual 🎀

okay so bestie, we're in the Kernel API Manual today and the star of the show is a lil struct called struct pci_epc_bar_rsvd_region. it's a whole vibe, it's giving "tiny but important," and honestly? it ate.

---

✨ NAME ✨

struct pci_epc_bar_rsvd_region — literally just a fixed subregion that lives behind a BAR 🫶

---

🌸 SYNOPSIS 🌸

here's the shape of it, no cap, copy it exactly:

struct pci_epc_bar_rsvd_region {
    enum pci_epc_bar_rsvd_region_type       type;
    resource_size_t offset;
    resource_size_t size;
 };

three members, zero drama. periodt 💅

---

🦋 Members 🦋

• type — the reserved region type, iykyk. it's an enum pci_epc_bar_rsvd_region_type situation and it tells you what kind of reserved region this is.
• offset — the offset within the BAR aperture. like, where inside the BAR this thing actually sits 📍
• size — the size of the reserved region. how much room it's taking up, bestie. a resource_size_t of pure real estate 🏠

ngl this page is short and sweet, so there's no scary warning here — just remember every field is exactly what it says, and don't go inventing extra ones 💀

and that's a wrap, bestie!! this one came straight out of ./include/linux, dated October 2026, and it goes by the iconique name struct pci_e..._rsvd_region(9). slay, mwah 💖✨🎀🦋🌸💅
