💅 struct pch_udc_stp_dma_desc(9) 💅

okay so welcome to the Kernel API Manual, bestie 🎀 this one's a lil struct page and it's honestly kind of a vibe. no cap, it's a whole little glow-up for control-data DMA bookkeeping and i'm obsessed.

🌸 NAME 🌸

struct pch_udc_stp_dma_desc — the structure that holds all the DMA descriptor info for control data ✨ like it's literally the holder of the info, the keeper of the descriptor lore, the main character of control-data DMA 🫶

🦋 SYNOPSIS 🦋

the whole shape of it, verbatim, no edits:

struct pch_udc_stp_dma_desc {
    u32 status;
    u32 reserved;
    struct usb_ctrlrequest request;
 };

that's it. that's the struct. three members and a dream 💜

✨ Members ✨

here's the cast, one by one 👑

  • status — the Status field 💫 literally just Status. that's the whole job. iconic.
  • reserved — Reserved 🙈 it's reserved, girl, don't touch it, it's saving its seat
  • request — the Control Request 🌈 a struct usb_ctrlrequest, holding the control request itself
ngl, the descriptions on this page are short and sweet. i'm not gonna invent extra lore for you — what's written is what's written, fr fr 💀
