STRUCT PCI_EPF_OPS(9)

💖 struct pci_epf_ops(9) 💖

okay so bestie, literally welcome to the Kernel API Manual ✨ — this is the page for struct pci_epf_ops, and ngl it's a whole vibe check on function pointers for performing EPF operations. no cap, let's get into it 🫶

🌸 NAME 🌸

struct pci_epf_ops — the set of function pointers for performing EPF operations 💅

---

🦋 SYNOPSIS 🦋

okay here's the actual shape of it, copied exactly, don't @ me:

struct pci_epf_ops {
    int (*bind)(struct pci_epf *epf);
    void (*unbind)(struct pci_epf *epf);
    struct config_group *(*add_cfs)(struct pci_epf *epf, struct
config_group *group);
 };

it's giving three little pointers and honestly they're all main characters in their own way 👑

🎀 Members 🎀

• bind — ops to perform when a EPC device has been bound to EPF device. this is the we're official now moment 😭💖
• unbind — ops to perform when a binding has been lost between a EPC device and EPF device. the breakup arc, lowkey sad 🥀
• add_cfs — ops to initialize function-specific configfs attributes. highkey the organizational one, keeping everything cute and filed away 🗂️✨

go read these next, bestie, they're all linked in the kernel file ./include/linux/pci-epf.h:

• struct pci_epf_header(9)
• struct pci_epc_event_ops(9)
• struct pci_epf_driver(9)
• struct pci_epf_bar_submap(9)
• struct pci_epf_bar(9)

like, that's a whole friend group right there 🌈👯‍♀️

real talk: this page lives in ./include/linux and it dropped October 2026. iconic behavior fr fr 💀🔥
