✨ ig3rdma_ena_irq ✨

okay so real talk, this is a page from the Kernel API Manual, and honestly? it's a short one, but she's iconic. we're talking about ig3rdma_ena_irq — the lil function that wakes an interrupt back up. enabling. turning it ON. the glow-up of interrupts, if you will 💅

🌸 NAME 🌸

ig3rdma_ena_irq — Enable interrupt ✨

that's it. that's the whole vibe. she enables. she's an interrupt enabler. 🫶

---

🦋 SYNOPSIS 🦋

void ig3rdma_ena_irq (struct irdma_sc_dev *dev , u32 idx );

bestie look at her, she returns void, she takes two things, she does not miss 😭✨

---

🎀 ARGUMENTS 🎀

• dev — pointer to the device structure. like, the device. the actual struct irdma_sc_dev situation. she needs to know which device, obviously 💖
• idx — vector index. which vector, bestie. it's a u32. that's the one you're enabling. no cap 🔥

---

👑 SEE ALSO 👑

• Kernel file ./drivers/infiniband/hw/irdma/ig3rdma_hw.c — yeah this is where she lives, go look at her in her natural habitat 🐚
• ig3rdma_disable_irq(9) — her evil twin. the opposite one. the one that turns it OFF. you're gonna need both, iykyk 😌

---

ngl the whole lesson here is: ig3rdma_ena_irq = on, ig3rdma_disable_irq = off. match them up and you're slaying 💀✨
