STRUCT CDNS_PCIE_EPF(9)

✨ NAME ✨

struct cdns_pcie_epf — bestie, this is the structure to hold info about endpoint function. That’s the whole vibe. 💖

okay so this is a Kernel API Manual page, and yes we’re gonna get into every lil detail, no cap.

🎀 SYNOPSIS 🎀

struct cdns_pcie_epf {
    struct cdns_pcie_epf *epf;
    struct pci_epf_bar *epf_bar[PCI_STD_NUM_BARS];
};

💅 Members 💅

• epf — info about virtual functions attached to the physical function. The member is typed struct cdns_pcie_epf *epf — yes, same struct name, iconic behavior, no notes. 💀
• epf_bar — reference to the pci_epf_bar for the six Base Address Registers. The array type is struct pci_epf_bar *epf_bar[PCI_STD_NUM_BARS];, and it’s giving “six BARs, all accounted for.” ✨
