💅 dwc2_gadget_handle_incomplete_isoc_out ✨

okay bestie so we're in the Kernel API Manual, page dwc2_gadget_...ete_isoc_out(9) 🎀 — yes the header itself is doing a little truncation moment, that's literally how it's printed, we are NOT fixing it, periodt.

✨ NAME ✨

dwc2_gadget_handle_incomplete_isoc_out — handle incomplete ISO OUT Interrupt 🦋

💖 SYNOPSIS 💖

void dwc2_gadget_handle_incomplete_isoc_out (struct dwc2_hsotg *hsotg );

no cap, that's the whole signature, one argument, void return, we love a lowkey function 🫶

🌸 ARGUMENTS 🌸

  • hsotg — The device state: 👑

🔥 DESCRIPTION 🔥

So this interrupt is basically the kernel going "bestie… something happened" 😭 — it fires to tell you that one of the following conditions occurred while transmitting an ISOC transaction:

  • Corrupted OUT Token for ISOC EP. 💀
  • Packet not complete in FIFO. 🙈

and then, because we are nothing if not proactive, the following actions will be taken:

  • Determine the EP 🎯
  • Set DCTL_SGOUTNAK and unmask GOUTNAKEFF if target frame elapsed. ⭐

that second bullet is the main character energy of this whole function, ngl — but fr fr it only happens if the target frame elapsed, so don't come for me, read the conditional 💅
