STRUCT D40_PHY_LLI_BIDIR(9)

✨ struct d40_phy_lli_bidir(9) ✨

okay so bestie, we're in the Kernel API Manual today and the star of the show is struct d40_phy_lli_bidir 💅 (yes the title is the same as the name, that's just how manpages roll, don't come for me)

---

🌸 NAME 🌸

struct d40_phy_lli_bidir — literally just a struct for a transfer, that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

struct d40_phy_lli_bidir {
    struct d40_phy_lli      *src;
    struct d40_phy_lli      *dst;
 };

look at her, two little pointer fields, living her best life 🫶

---

💖 Members 💖

• src — the register settings for the src channel. like, all the configuration energy for where stuff comes from 👑
• dst — the register settings for the dst channel. same deal, but for where stuff's headed 🎯

---

🌈 Description 🌈

no cap, this one's simple: all DMA transfers have a source and a destination. every single one. that's the whole reason this struct exists — one pointer for each side of the transfer, holding their register settings ✨
