dwc3_send_ga...eric_command(9)

💅 dwc3_send_ga...eric_command(9) — from the Kernel API Manual ✨

okay so bestie, listen. this one's from the Kernel API Manual, and the function we're hyping up today is dwc3_send_gadget_generic_command — yes the page title got chopped up like a bad haircut (dwc3_send_ga...eric_command(9), iconic of it honestly), but the real name is right there in the NAME section. let's get into it 🫶

---

🌸 NAME 🌸

dwc3_send_gadget_generic_command — literally just: issue a generic command for the controller. that's it, that's the whole vibe. 💅

---

✨ SYNOPSIS ✨

int dwc3_send_gadget_generic_command (struct dwc3 *dwc , unsigned int
cmd , u32 param );

no cap, that's the whole signature. three little arguments and one int coming back at you. 🎀

---

🦋 ARGUMENTS 🦋

• dwc — pointer to the controller context. it's the main character here, give it a little respect 👑
• cmd — the command to be issued. the thing you actually want to happen, you know?
• param — command parameter. the little sidekick that comes along with the command 🧚

---

🌈 DESCRIPTION 🌈

okay so this is the part where i hold your hand, bestie. the caller should take care of locking. not us! not this function! you. so lock up before you call this, fr fr 🔒

then it issues cmd with a given param to dwc, and waits for its completion. that's the whole flow — send it, then wait. literally "send and wait", the most patient little function in the gadget driver 💀

that's the page, bestie!! mwah 💋 this lil' writeup came from ./drivers/usb/dwc3, and it's dated October 2026 — so yeah, future-dated manual page, main character energy only 🌟 and the page it lives under is still stylin' as dwc3_send_ga...eric_command(9). slay, stay locked, stay hydrated 💜🦋
