igb_init_interrupt_scheme(9)

💖 igb_init_interrupt_scheme(9) — like, the whole glow-up ✨

okay so bestie, welcome to the Kernel API Manual (section 9, yes, the ~fancy~ one 🎀). Today's main character is igb_init_interrupt_scheme, and honestly? she's the one who sets the whole party up before anyone else shows up. let's get into it 💅

---

✨ NAME ✨

igb_init_interrupt_scheme — she initializes interrupts and allocates queues/vectors. that's it, that's the vibe 🦋

---

🌸 SYNOPSIS 🌸

int igb_init_interrupt_scheme (struct igb_adapter *adapter , bool msix
);

like look at that signature. so clean. so iconic. 👑

---

🎀 ARGUMENTS 🎀

• adapter — the board private structure you're gonna initialize. she's the whole personality of the board tbh, so be nice to her 💖
• msix — a boolean value of the MSIX capability. yes/no energy. does she have MSIX or not, bestie, pick one 🌈

---

🔥 DESCRIPTION 🔥

so what does she actually do? okay so — this function initializes the interrupts, and it allocates all of the queues. all of them. every single one. no queues left behind, periodt 💀✨

that's genuinely the whole description ngl. short, sweet, and gets straight to the point. main character energy 🧚
