dwc2_driver_probe(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dwc2_driver_probe(9) — the Kernel API Manual glow-up 🎀

okay bestie, welcome to the dwc2_driver_probe(9) page from the Kernel API Manual — yes, that's the manual name, we're being official today 💖 this is the ✨ Called when the DWC_otg core is bound to the DWC_otg driver ✨ situation, and honestly? it's giving main character energy for the whole USB bring-up. let's get into it 🦋

✨ SYNOPSIS ✨

int dwc2_driver_probe (struct platform_device *dev );

that's it. one function, one argument, one int coming back at you. no cap 🔥

🌸 ARGUMENTS 🌸

  • dev — the Platform device. that's the whole assignment, she's the platform device, she's the one showing up to the party 🎀

💅 DESCRIPTION 💅

okay so picture this: this routine is literally the vibe check that builds out all the driver components you need to actually control the device — and bestie, there are exactly three of them:

  • the core
  • the HCD
  • the PCD

yeah. all three. it creates those driver components, then it initializes the device. ✨ icon status ✨

and where do all these shiny new components live? they get stored in a dwc2_hsotg structure, obviously. slay 💖

then — and this is the important part, iykyk — a reference to the dwc2_hsotg gets saved in the device private data. why? because that's literally the whole point: it's what lets the driver go find that dwc2_hsotg structure again on subsequent calls to driver methods for this device. like leaving your own little sticky note so future-you can find the snacks 🍓

so fr fr, keep that reference alive and everything downstream just works. periodt 🫶
