e1000_alloc_ring_dma(9)

💖 e1000_alloc_ring_dma — it's giving "kernel API manual" energy 💖

okay so bestie, we're in the e1000_alloc_ring_dma(9) page, which lives in the Kernel API Manual and honestly? it's a whole little icon. she does exactly one (1) thing and she does it slayfully.

✨ NAME ✨

e1000_alloc_ring_dma — allocate memory for a ring structure 🎀

like. that's the whole vibe. it hands out memory so a ring can do ring things. no cap.

---

🌸 SYNOPSIS 🌸

int e1000_alloc_ring_dma (struct e1000_adapter *adapter , struct
e1000_ring *ring );

yes she's an int, yes she takes two pointers, yes the source code wraps the line like that, and yes we're keeping it exactly as-is because facts are facts 🫶

---

💅 ARGUMENTS 💅

• adapter — the board private structure. this is the "who's the parent" of it all, main character energy fr fr.
• ring — the ring struct we're out here allocating DMA for. she's the one getting the memory. periodt.

like I said. the whole group chat. 🌈

---

💀 real talk though: this is a kernel API page, so nothing here is a "try it in production and see what happens" moment — it's reference material, and the reference material is what it is. no invented behavior over here, bestie, we keep it honest.

---

and that's the page, bestie — short, sweet, and fully documented 🍓

this cutie was brought to you by the source file ./drivers/net/ethernet/intel/e... (yes, the terminal just truncates her name like that, she's mysterious 💜) and she's dated October 2026, so she's lowkey from the future. iconic. no notes. 💅✨🧚
