💅 ioat_dma_do_interrupt_msix(9)

okay so first thing, bestie, we're in the Kernel API Manual today — yes, that one, the big serious one — and we're talking about ioat_dma_do_interrupt_msix. Iconic name, I know. Say it three times fast, I dare you. 🫶

✨ NAME ✨

ioat_dma_do_interrupt_msix — the handler you use for vector-per-channel interrupt mode 🎀

That's it. That's the whole vibe. One job, one mode, no cap. 💅

---

🌸 SYNOPSIS 🌸

irqreturn_t ioat_dma_do_interrupt_msix (int irq , void *data );

Look at that signature. Clean. Minimal. Main character energy fr fr. ⭐

---

🦋 ARGUMENTS 🦋

• irq — the interrupt id, aka which interrupt we're talking about here 💖
• data — the interrupt data, the little payload that comes along for the ride 🍓

Two arguments. That's the whole lineup. Not me being obsessed with how tidy this is 😭

---

🔥 SEE ALSO 🔥

• Kernel file ./drivers/dma/ioat/dma.c — that's where the magic lives, go read the source bestie 💜
• ioat_dma_do_interrupt(9) — the sibling handler, iykyk 👀
• ioat_update_pending(9)
• ioat_check_space_lock(9)
• __ioat_cleanup(9)

Read them in order or read them out of order, I'm not your mom. But like… read them. 📚

ngl there's no extra DESCRIPTION section here, no warnings, no exit statuses — this page is short and it knows it. What you see is what you get. Don't go inventing behaviour that isn't written down, that's not slay, that's just making stuff up. 🙈

kay that's the whole page, hope you ate 💅✨

sign-off time 🎀 — this lil beauty comes from the kernel file ./drivers/dma/ioat/dma.c, dated October 2026, and it's page ioat_dma_do_interrupt_msix(9) of the Kernel API Manual. mwah 💖
