ish_irq_handler(9)

💅 ish_irq_handler(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to the glow-up of ish_irq_handler(9), straight out of the Kernel API Manual. it's giving "small function, big responsibilities" and honestly? we're obsessed. let's get into it ✨

🌸 NAME 🌸

ish_irq_handler — the ISH IRQ handler, aka the girl who answers the door when the interrupt knocks 🔔

🦋 SYNOPSIS 🦋

irqreturn_t ish_irq_handler (int irq , void *dev_id );

💖 ARGUMENTS 💖

• irq — the irq number, literally just the number of the interrupt in question. she's an int. she's doing her best. 🔢
• dev_id — the ishtp device pointer, aka the little handle that tells you which device we're talking about 🫶

👑 DESCRIPTION 👑

so here's the vibe: ish_irq_handler is the ISH IRQ handler. if an interrupt gets generated and it's for ISH, then this function will process the interrupt. that's it, that's the whole personality. no cap, no drama, just handling her interrupts and slaying 💅

ngl this is the "if it's for me, I'll deal with it" energy we should all aspire to 🙈
