ppe_ring_queue_map_set(9)

💖 ppe_ring_queue_map_set(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's called ppe_ring_queue_map_set and it's literally the matchmaker between PPE queues and Ethernet DMA rings. let's get into it 🎀

---

✨ NAME ✨

ppe_ring_queue_map_set — Set the PPE queue to Ethernet DMA ring mapping 🦋

---

🌸 SYNOPSIS 🌸

int ppe_ring_queue_map_set (struct ppe_device *ppe_dev , int ring_id ,
const u32 *queue_map );

no cap, that's the whole signature. three args, one int coming back at you 💅

---

💜 ARGUMENTS 💜

• ppe_dev — the PPE device, your main character struct 🫶
• ring_id — the Ethernet DMA ring ID. yes, that ring ✨
• queue_map — a bit map of queue IDs that belong to the given Ethernet DMA ring 🌸

---

👑 DESCRIPTION 👑

so what does it actually do? it configures the mapping from a set of PPE queues to a given Ethernet DMA ring. that's it, that's the vibe — you point at a ring, you hand over your bitmap of queues, and the mapping gets set up. iconic behavior honestly 🔥

---

⭐ RETURN ⭐

• 0 on success 💖
• a negative error code on failure 😭 (so like, always check, bestie, fr fr)

ok that's the page!! mwah 💋 this one came out of ./drivers/net/ethernet/qualcom... and it's dated October 2026 — so yeah, future girl summer 🌸✨ bye bestie, go map some queues 💅💖
