gsi_isr(9)

💅 gsi_isr(9) — from the Kernel API Manual, bestie

okay so this is a page straight out of the Kernel API Manual, and it's about gsi_isr — the top level GSI interrupt service routine. it's short, it's sweet, and it's literally the front door for GSI interrupts. let's get into it 🫶

✨ NAME ✨

gsi_isr — Top level GSI interrupt service routine 👑

🎀 SYNOPSIS 🎀

irqreturn_t gsi_isr (int irq , void *dev_id );

🌸 ARGUMENTS 🌸

• irq — the interrupt number, and honestly? it's ignored. not read, not checked, not used. it's just there being decorative. main character energy but with zero lines 💀
• dev_id — the GSI pointer that you handed over to request_irq. this is the one that actually matters, bestie.

🦋 DESCRIPTION 🦋

so this is the main handler function registered for the GSI IRQ — the top level one, the one that gets called first. and here's the cute part: each type of interrupt has its own separate handler function, and gsi_isr is the one that calls into them from here. it's giving head-of-the-group-chat energy, fr fr. 🌈
