devlink_por...s_pci_pf_set(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, grab your lil kernel-hacker notebook because we're in the Kernel API Manual today and this one is genuinely a whole vibe ✨ It's a tiny function, she's not doing the most, but she's important — she stamps the PCI PF port attributes onto a devlink port. Let's get into it 🫶

✨ NAME ✨

devlink_port_attrs_pci_pf_set — literally just sets the PCI PF port attributes 💖 no cap, that's the entire job.

🎀 SYNOPSIS 🎀

void devlink_port_attrs_pci_pf_set (struct devlink_port *devlink_port ,
u32 controller , u16 pf , bool external );

she's a void, she returns nothing, she simply does 👑

🌸 ARGUMENTS 🌸

  • devlink_port — the devlink port in question, the main character of this whole operation 💅
  • controller — a u32 with the associated controller number for the devlink port instance 🔥
  • pf — a u16, the associated PCI function number for the devlink port instance 🌈
  • external — a bool that indicates if the port is for an external controller 👀 (yes this matters, don't skip it)
