configure_new_device(9)

💅 configure_new_device — the Kernel API Manual page, but make it make sense

okay so bestie, welcome to the configure_new_device(9) glow-up ✨ this is a kernel API manual page and we're gonna get through it together, no cap. grab a boba, we're configuring stuff.

✨ NAME ✨

configure_new_device — configures the PCI header information of one board. that's it, that's the whole vibe. one board, header info, configured. periodt 💅

🫶 SYNOPSIS 🫶

u32 configure_new_device (struct controller *ctrl , struct pci_func *func , u8 behind_bridge , struct resource_lists *resources );

look at that signature, it's giving main character energy 🌈 four whole arguments, returns a u32. iconic honestly.

🎀 ARGUMENTS 🎀

• ctrl — pointer to the controller structure. yes bestie, a pointer, handle with care 🙈
• func — pointer to the function structure. another pointer, we stay pointing 🌸
• behind_bridge — 1 if this is a recursive call, 0 if it's not. that's the whole bit. one or zero. binary icon behavior 💀
• resources — pointer to the set of resource lists. pointer number three, we love a consistent aesthetic 🦋

💖 DESCRIPTION 💖

returns 0 if success. that's literally it. no notes. 0 means success, and that is the entire description 😭✨
