dwc2_hc_do_ping(9)

💖 dwc2_hc_do_ping(9) — NAME 💖

okay bestie, welcome to the dwc2_hc_do_ping(9) page from the Kernel API Manual — yes, the one with the (9) and the whole kernel-api vibe. This function literally starts a PING transfer, and it's giving tiny-but-important host-channel moment. ✨

✨ SYNOPSIS ✨

void dwc2_hc_do_ping (struct dwc2_hsotg *hsotg , struct dwc2_host_chan *chan );

🎀 ARGUMENTS 🎀

• hsotg — the programming view of the DWC_otg controller. Basically the controller's whole setup energy, handed over as a pointer. 🫶
• chan — the information needed to initialize the host channel. Everything the host channel needs for its setup era. 💅

🦋 DESCRIPTION 🦋

okay so real talk: this function should only be called in Slave mode. Do not freestyle it anywhere else, bestie — Slave mode only, no cap. 😭

Here's the whole sequence, and it's literally two steps: the Do Ping bit gets set in the HCTSIZ register, and then the channel is enabled. That's the transfer-starter slay. Periodt. 💅
