💖 pci_epc_add_epf 💖

okay so bestie, welcome to the Kernel API Manual — this one's called pci_epc_add_epf (that's the 9th section, iykyk) and it's literally about binding a PCI endpoint function to an endpoint controller. no cap, that's the whole vibe. let's get into it 🫶

✨ NAME ✨

pci_epc_add_epf — bind a PCI endpoint function to an endpoint controller 🎀

🌸 SYNOPSIS 🌸

int pci_epc_add_epf (struct pci_epc *epc , struct pci_epf *epf , enum
       pci_epc_interface_type type );

like, it returns an int, bestie. that's the tea ☕

🦋 ARGUMENTS 🦋

  • epc — the EPC device that the endpoint function should get added to. it's the main character here 👑
  • epf — the endpoint function that's being added. the one getting bound, periodt 💅
  • type — tells you whether the EPC is connected to the primary or the secondary interface of the EPF. pick your lane ✨

💜 DESCRIPTION 💜

so a PCI endpoint device can have one or more functions — like, it's not a one-function-only situation, she's multifaceted 🧚 in the case of PCIe, the spec allows up to 8 PCIe endpoint functions. iconic honestly.

invoke pci_epc_add_epf to add a PCI endpoint function to an endpoint controller. that's it, that's the function 💖
