s5p_set_dma_hashdata(9)

💅 s5p_set_dma_hashdata ✨

okay bestie, welcome to the Kernel API Manual page for s5p_set_dma_hashdata(9) — yes that's the whole title, yes it's a mouthful, no we're not changing it 🫶

---

✨ NAME ✨

s5p_set_dma_hashdata — start DMA with sg 🚀

That's it. That's the whole job. It starts the DMA using an sg. Slay.

---

🦋 SYNOPSIS 🦋

void s5p_set_dma_hashdata (struct s5p_aes_dev *dev , const struct
scatterlist *sg );

notice the void — this one gives nothing back, it's a giving function, not a receiving one 😌💖

---

🌸 ARGUMENTS 🌸

• dev — the device 💻 that's it, that's the descriptor, it's literally just the device, she's the main character
• sg — the scatterlist that's ready to DMA transmit 📤 like she's packed and waiting at the door, fully ready to go

fr fr both of these are the ones you hand over — no defaults, no fallbacks, no "guess what I meant". You bring the device and you bring the ready-to-transmit scatterlist. periodt 💅
