dim2_ahb_isr(9)

💖 dim2_ahb_isr(9) — the Kernel API Manual, but make it group chat 💖

okay so bestie, buckle up, we're doing a kernel API manual page today and honestly? it's giving "small but mighty" ✨ this one lives in the dim2 section of the Kernel API Manual, and it's about the AHB interrupt service routine 🎀

---

🌸 NAME 🌸

dim2_ahb_isr — interrupt service routine. literally that's the whole vibe, it's the ISR, no cap 💅

---

✨ SYNOPSIS ✨

irqreturn_t dim2_ahb_isr (int irq , void *_dev );

yes the spacing is exactly like that, don't come for me, I'm just the messenger 🫶

---

🦋 ARGUMENTS 🦋

• irq — the irq number. that's it, that's the argument 💫
• _dev — the private data. it's a void *, so like… it could be anything, main character energy fr 🙈

---

💜 DESCRIPTION 💜

so what does it do? glad you asked, bestie 🔥

It acknowledges the interrupt, and then it services each initialized channel — if needed — in task context 👑

like — the way that ack-then-service pipeline works is honestly iconic. and note the "in task context" part, that's not a throwaway detail, that's the detail 🎀

ngl bestie, if you're poking around here you probably want the rest of that list too. read the docs, hydrate, and remember: it acknowledges the interrupt and services each initialized channel, if needed, in task context. periodt 💅

🌸 and finally, a cute little sign-off: this page hangs out in ./drivers/staging/most/dim2, it's dated October 2026, and yeah — that's the whole footer, so consider yourself informed, bestie. ily, go ack some interrupts 💜✨🍓
