xudc_ep0_stall(9)

📦 version 7.3.1, in nixpkgs unstable

💅 xudc_ep0_stall — from the Kernel API Manual ✨

Okay bestie, gather round, because we're talking about xudc_ep0_stall(9) — a whole function that does exactly one iconic thing and we're gonna stan it properly. 🫶

✨ NAME ✨

xudc_ep0_stall — stall endpoint zero. That's it, that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

void xudc_ep0_stall (struct xusb_udc *udc );

No cap, that's the entire signature. Returns void, so don't go looking for a return value, she gives you nothing back and she's at peace with that. 💅

🦋 ARGUMENTS 🦋

  • udc — pointer to the udc structure. Yep, that's the one and only thing you hand her. She takes it, she does her thing, she does not elaborate. 🙈

💖 DESCRIPTION 💖

So like, this function stalls endpoint zero. That's the assignment. That's literally what it says on the tin. ✨ Endpoint zero? Stalled. By this function. The way that xudc_ep0_stall just does that one job and doesn't overcomplicate it? Main character energy fr fr. 👑

🌈 SEE ALSO 🌈

Okay this is the part where the page just keeps going and going and honestly? Iconic behavior. Here's the whole fam, and yes you're getting every single one of them because we don't do half-finished lists around here. 💀

The kernel file you wanna peek at is ./drivers/usb/gadget/udc/udc-xilinx.c, and then there's this absolute squad:

Like, look at that list. Forty-eight little cross-references all living their best lives. Obsessed. 🔥

Ngl bestie, if you're here because endpoint zero is acting up, at least now you know who to call. Go read the other ones too, they're all in ./drivers/usb/gadget/udc, iykyk. 🧚

And that's the page!! Sourced straight from ./drivers/usb/gadget/udc, dated October 2026, and if you need me I'll be right here hyping up endpoint zero forever. Slay, bye! 💜🍓⭐
