cdns3_ep_inc_trb(9)

🎀 cdns3_ep_inc_trb — Kernel API Manual 🎀

okay bestie, this is the Kernel API Manual entry for cdns3_ep_inc_trb(9) — yes, the little TRB-index-bumping moment. let’s get into it 💅✨

✨ NAME ✨

cdns3_ep_inc_trb — increment a trb index. periodt. 🎀

💖 SYNOPSIS 💖

here’s the exact signature, no cap:

void cdns3_ep_inc_trb (int *index , u8 *cs , int trb_in_seg );

🦋 ARGUMENTS 🦋

• index — Pointer to the TRB index to increment. like, it’s literally pointing at the index you’re bumping up 🫶
• cs — Cycle state. the cycle-state situation, iconic 💫
• trb_in_seg — number of TRBs in segment. the count of TRBs chillin’ in that segment 🍓

🌸 DESCRIPTION 🌸

okay so the index should never point to the link TRB. after incrementing, if it is pointing to the link TRB, it wraps around to the beginning and reverts the cycle state bit. and yes — the link TRB is always at the last TRB entry. that’s the vibe 💀✨
