💅 dwc2_hcd_queue_transactions(9) 💅

okay bestie, welcome to the Kernel API Manual entry for dwc2_hcd_queue_transactions — yes, that whole iconic name is the title, and we’re gonna get through it together 🫶

✨ NAME ✨

dwc2_hcd_queue_transactions — processes the currently active host channels and queues transactions for these channels to the DWC_otg controller. Called from the HCD interrupt handler functions. 💫

🌸 SYNOPSIS 🌸

void dwc2_hcd_queue_transactions (struct dwc2_hsotg *hsotg , enum
dwc2_transaction_type tr_type );

🎀 ARGUMENTS 🎀

• hsotg — the HCD state structure, aka the main-character state object for your host controller 💅
• tr_type — the type(s) of transactions to queue: non-periodic, periodic, or both. pick your vibe ✨

🦋 DESCRIPTION 🦋

⚠️ no cap, bestie: dwc2_hcd_queue_transactions() must be called with interrupt disabled and spinlock held. that’s the rule, not a suggestion 💀
