STRUCT CI_HW_EP(9)

💖 NAME 💖

okay so bestie, welcome to the struct ci_hw_ep(9) page — it's the manual page for struct ci_hw_ep, aka the endpoint representation. Yes, we're doing a whole struct field-by-field, and honestly? iconic. ✨

🦋 SYNOPSIS 🦋

Here's the struct exactly as it is, no edits, no cap:

struct ci_hw_ep {
    struct usb_ep                           ep;
    u8 dir;
    u8 num;
    u8 type;
    char name[16];
    struct {
      struct list_head        queue;
      struct ci_hw_qh         *ptr;
      dma_addr_t dma;
    } qh;
    int wedge;
    struct ci_hdrc                          *ci;
    spinlock_t *lock;
    struct dma_pool                         *td_pool;
    struct td_node                          *pending_td;
 };

psst: pending_td is right there in the struct, but the Members section below doesn't give it its own little blurb — and I'm not out here inventing one. 💅

🌸 Members 🌸

Time for the member-by-member vibe check, bestie:

• ep — endpoint structure for gadget drivers
• dir — endpoint direction (TX/RX)
• num — endpoint number
• type — endpoint type
• name — string description of the endpoint
• qh — queue head for this endpoint
• wedge — is the endpoint wedged
• ci — pointer to the controller
• lock — pointer to controller's spinlock
• td_pool — pointer to controller's TD pool
