STRUCT PCH_UDC_DATA_DMA_DESC(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME

So bestie, this page is struct pch_udc_data_dma_desc(9) — a Kernel API Manual entry, no big deal, just your fave little C struct. It's literally the structure that holds the DMA descriptor information for data. That's the whole vibe. 🎀

✨ SYNOPSIS

Here's the shape of it, and yes you have to keep every field exactly like this:

struct pch_udc_data_dma_desc {
    u32 status;
    u32 reserved;
    u32 dataptr;
    u32 next;
 };

Four u32 fields, all iconic, all necessary. Look at her go. 🦋

🌸 MEMBERS

Okay so here's the member-by-member breakdown, no skips, no cuts:

  • status — the status quadlet, living its truth. ⭐
  • reserved — reserved. It's giving "don't touch, it's not for you". 🙈
  • dataptr — the buffer descriptor. The pointer that actually matters here. 🔥
  • next — the next descriptor. She points forward, always. 👑
ngl that's the entire struct — four fields, zero drama. Slay.

🦋 SEE ALSO

First things first, the kernel file herself: ./drivers/usb/gadget/udc/pch_udc.c — that's where the struct lives and where all of these friends hang out too:

Like, that's the whole group chat. Every single one of them, mwah. 💜

Okay that's the page!! Written down from the source at ./drivers/usb/gadget/udc, dated October 2026 — screenshot it, cite it, send it to your bestie. Periodt. 🫶✨
