STRUCT DWC3_EVENT_BUFFER(9)

✨ struct dwc3_event_buffer(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one is a little struct from ./drivers/usb/dwc3 and it's literally the software representation of an event buffer. that's it, that's the vibe. software. event buffer. representation. slay.

🌸 SYNOPSIS 🌸

struct dwc3_event_buffer {
    void *buf;
    void *cache;
    unsigned int            length;
    unsigned int            lpos;
    unsigned int            count;
    unsigned int            flags;
  #define DWC3_EVENT_PENDING      BIT(0);
    dma_addr_t dma;
    struct dwc3             *dwc;
 };

like look at her. gorgeous. no notes. 🫶

💅 Members 💅

• buf — _THE_ buffer. not a buffer, THE buffer. the main character, honestly. 👑
• cache — the buffer cache used in the threaded interrupt. yes bestie, threaded. 🌈
• length — size of this buffer, i.e. how much buffer there is. iconic of her to keep track. 📏
• lpos — event offset. that's the position, don't overthink it. 🎀
• count — cache of last read event count register. it's a cache, of the last read one, from the event count register. all three details matter, iykyk. 💜
• flags — flags related to this event buffer. flags. for this buffer. related to the event. periodt. 🚩
• dma — a dma_addr_t. that's the whole description and honestly? respect for the brevity. 💀
• dwc — pointer to DWC controller. hi controller 👋

go read them fr fr, they all ate. 🔥

ngl bestie the one thing to remember: this is just the software side of things. no cap, that's the entire point of her. 💖

and that's the page!! 🦋💫 this was served up from ./drivers/usb/dwc3, dated October 2026, in the Kernel API Manual — struct dwc3_event_buffer(9), mwah, take care of her, bye bestie! 💅✨🍓
