dwc2_hcd_sel...transactions(9)

✨ NAME ✨

okay so bestie, this page is from the Kernel API Manual, and it's all about dwc2_hcd_select_transactions 💅✨. She selects transactions from the HCD transfer schedule and assigns them to available host channels. Called from the HCD interrupt handler functions. That's the whole gig, no cap 🫶.

🌸 SYNOPSIS 🌸

enum dwc2_transaction_type dwc2_hcd_select_transactions (struct dwc2_hsotg *hsotg );

🧸 ARGUMENTS 🧸

• hsotg — the HCD state structure. That's the one thing she needs, bestie 🎀.

🔁 RETURN 🔁

The types of new transactions that were assigned to host channels. Literally which new transactions got picked and sent to the channels 💖.
