💖 dw_pcie_ep_init(9) — the kernel API manual, but make it make sense 💖

okay so bestie, welcome to the dw_pcie_ep_init page from the Kernel API Manual. yes it's a manpage, no it doesn't have to be boring. let's get into it 🫶

✨ NAME ✨

dw_pcie_ep_init — literally just: initialize the endpoint device. that's the whole vibe. 🎀

✨ SYNOPSIS ✨

int dw_pcie_ep_init (struct dw_pcie_ep *ep );

one function, one pointer, one int coming back at you. iconic honestly.

✨ ARGUMENTS ✨

  • ep — the DWC EP device. that's your endpoint bestie. hand it over and let the function do its thing 💅

✨ DESCRIPTION ✨

so what does it actually do? it initializes the endpoint device. and like, not just vibes — it genuinely does the work: it allocates resources and creates the EPC device using the endpoint framework. no cap, that's the whole job. main character energy from a single function call 🔥

✨ RETURN ✨

  • 0 on success — slay, we ate 💅✨
  • errno otherwise — i.e. if it doesn't work out, you get an errno back. not a 0, not a vibe. 😭

✨ SEE ALSO ✨

ngl if you're calling this you probably also want the deinit and cleanup pages open in another tab. that's not me being technical, that's just literally what's listed above. 💀

and that's the page!! 🎀 this gem lives under ./drivers/pci/controller/dwc, dated October 2026, and it's filed as dw_pcie_ep_init(9) — periodt. 💖✨🌸
