pch_udc_ep_set_bufsz(9)

✨ NAME ✨

pch_udc_ep_set_bufsz — sets the maximum packet size for the endpoint, bestie 💖

🌸 SYNOPSIS 🌸

void pch_udc_ep_set_bufsz (struct pch_udc_ep *ep , u32 buf_size , u32
       ep_in );

It returns void btw — no return value, no little gift back, it just does the thing, periodt ✨

🎀 ARGUMENTS 🎀

• ep — a reference to a structure of type pch_udc_ep_regs. Like, it's the endpoint you're out here trying to configure. She's the main character of this call 🫶
• buf_size — the buffer word size. This is the number you're feeding in, the whole point of the operation, the moment 💅
• ep_in — EP is IN. That's literally the whole description, no cap — it's the flag that says this endpoint is IN 👑

🦋 SEE ALSO 🦋

So like… the kernel file lives at ./drivers/usb/gadget/udc/pch_udc.c, and honestly the whole friend group shows up here. Obsessed with how long this list is, fr fr 😭

Okay bye bestie, this page came straight out of ./drivers/usb/gadget/udc, dated October 2026 — go set some buffer sizes and slay 💅✨🌸
