💅 sxgbe_init_dma_engine(9) — bestie's guide to DMA init ✨

okay so you're in the Kernel API Manual, section 9, and today's main character is sxgbe_init_dma_engine 🫶 buckle up, this one's short but it's important.

---

🌸 NAME 🌸

sxgbe_init_dma_engine — DMA init. that's it. that's the job. she inits the DMA 💖

---

✨ SYNOPSIS ✨

int sxgbe_init_dma_engine (struct sxgbe_priv_data *priv );

returns an int, takes one pointer, very demure, very mindful 🎀

---

🦋 ARGUMENTS 🦋

• priv — the driver's private structure. yes queen, the whole struct sxgbe_priv_data comes through the door 👑

---

💜 DESCRIPTION 💜

so what actually happens? it inits the DMA by invoking the specific SXGBE callback — that's the vibe, that's the whole move 🔥

some DMA parameters can be passed down from the platform, iykyk. but if they're not passed, a default is kept for the MAC or GMAC — so you're never left hanging with nothing, the fallback is literally built in 💅 no cap.
