dwc2_dump_channel_info(9)

💅 dwc2_dump_channel_info(9) — like, the Kernel API Manual but make it make sense ✨

okay bestie, buckle up, we're looking at dwc2_dump_channel_info from the Kernel API Manual 💖 this one's a little diagnostic darling — it's the function you call when you wanna see what a host channel is actually up to. short page, but every crumb matters, so let's go 🍓

---

🌸 NAME 🌸

dwc2_dump_channel_info — literally just prints out the state of a host channel. that's it. that's the whole vibe. 💅

---

✨ SYNOPSIS ✨

void dwc2_dump_channel_info (struct dwc2_hsotg *hsotg , struct
dwc2_host_chan *chan );

returns nothing (void), takes two pointers, no cap 🫶

---

🎀 ARGUMENTS 🎀

• hsotg — the programming view of the DWC_otg controller 👑 like, the big-picture controller context, the main character we're all here for.
• chan — pointer to the channel to dump 💖 the specific one you want the tea on.

---

🦋 DESCRIPTION 🦋

so here's the thing, and this is highkey important: it must be called with interrupt disabled and spinlock held 🔥 no exceptions, bestie. that's not a suggestion, that's the contract. do it wrong and the vibe check fails catastrophically 😭

---

⭐ NOTE ⭐

heads up, this function is on the way out 👋 it will be removed once the peripheral controller code is integrated and the driver is stable. so like, enjoy it while it lasts, iykyk 💀
