dwc2_port_resume(9)

✨ dwc2_port_resume — a kernel API manual moment ✨

okay so bestie, this is a page from the Kernel API Manual (the dwc2_port_resume(9) one, iykyk) and it's lowkey a tiny little function with a very specific job 💅

---

🌸 NAME 🌸

dwc2_port_resume — Exit controller from suspend mode for host.

like, it wakes the host side back up out of suspend. that's the whole vibe. periodt 🫶

---

🎀 SYNOPSIS 🎀

int dwc2_port_resume (struct dwc2_hsotg *hsotg );

that's it. one argument, one return value. simple queen behavior ✨

---

🦋 ARGUMENTS 🦋

• hsotg — Programming view of the DWC_otg controller 👑

(yeah, that's the literal description and honestly? it's giving "you already know what this is" energy. it's the controller's programming view, bestie. hand it over and let it cook.)

---

💜 RETURN 💜

not zero if it failed to exit suspend mode for host 😭 — so non-zero = things did not slay. 0 = success, we're so back 🌈

---

⭐ DESCRIPTION ⭐

This function is for exiting Host mode suspend. that's its whole main character moment 💫

⚠️ Must NOT be called with interrupt disabled or spinlock held. ⚠️

fr fr, do not do that. that's a hard no. like, the way that this is a big deal — interrupting with interrupts off or a spinlock in your hand is not the move, bestie. respect the caveat 🙈

🧚 and that's the whole page! the ./drivers/usb/dwc2 source and the October 2026 date are the little footer crumbs at the bottom of the original, so consider them officially shouted out here at the end instead. mwah 💋 🌸 🦋 💅
