geni_configure_xfer_mode(9)

💅 geni_configure_xfer_mode(9) — from the Kernel API Manual, bestie 🎀

okay so this one is literally the "pick your transfer mode" function and honestly? she's simple, she's iconic, she gets straight to the point. no cap. ✨

---

✨ NAME ✨

geni_configure_xfer_mode — set the transfer mode. that's it, that's the whole job 🫶

---

💖 SYNOPSIS 💖

int geni_configure_xfer_mode (struct geni_se *se , enum
geni_se_xfer_mode mode );

---

🌸 ARGUMENTS 🌸

• se — a pointer to the concerned serial engine. yes, that serial engine, the one you're worried about 👀
• mode — the SE data transfer mode. this is you choosing your vibe 🦋

---

🧚 DESCRIPTION 🧚

so basically: you call this and it sets the transfer mode to either FIFO or DMA, depending on the mode that the protocol driver specified. that's the tea ☕ the protocol driver says "this one," and this function makes it happen. lowkey elegant.

---

⭐ RETURN ⭐

returns 0 if successful — otherwise it returns an error value 😭 so like, always check. fr fr.

💀 reminder: only FIFO or DMA, only whatever the protocol driver told you. don't be out here inventing modes, bestie. 🙈
