gic_get_c0_fdc_int(9)

💖 gic_get_c0_fdc_int(9) — the Kernel API Manual, bestie edition 💖

Okay so picture this: you're deep in the MIPS kernel, it's 2am, and this lil function — gic_get_c0_fdc_int, from the Kernel API Manual — is here to hand you the interrupt number you've been looking for. Yeah. That one. Let's gooo. ✨

🦋 NAME 🦋

gic_get_c0_fdc_int — Return fast debug channel interrupt virq 💅

Like, it literally returns the virq for the fast debug channel interrupt. The name is not lying to you, bestie, for once. 👑

---

🌸 SYNOPSIS 🌸

int gic_get_c0_fdc_int (void );

No args, no drama. She takes nothing and she gives you an int. Iconic behaviour honestly. 🎀

---

🫶 ARGUMENTS 🫶

• void — no arguments. Not a single one. Empty handed. Nada. She doesn't want your parameters, she doesn't need them, she is ✨self-sufficient✨. 😭

---

💜 DESCRIPTION 💜

So what does she actually do? She determines the virq number — that's virtual interrupt request number, iykyk — to use for fast debug channel (FDC) interrupts, which may be routed via the GIC. Yes, may be. That's the vibe. No cap. 🌈

And then?

She returns the virq number. Or a negative error number if things went sideways. 💀

That's it. That's the whole function. Short, sweet, absolutely main character energy. Not every kernel function needs to be a 400-line saga, and honestly? Respect. 🙈

⭐ SEE ALSO ⭐

Go read these next, bestie, they're all besties with this one:

• Kernel file ./arch/mips/include/asm/mips-gic.h enum mips_gic_local_interrupt(9)
• mips_gic_present(9)
• mips_gic_vx_map_reg(9)
• gic_get_c0_compare_int(9)
• gic_get_c0_perfcount_int(9)

The whole GIC girl squad, fr fr. Read them in order, or don't, I'm not your mom. 🍓🧚

That's a wrap, gorgeous. This page lives under ./arch/mips/include/asm, dated October 2026, and it's called gic_get_c0_fdc_int(9) — go forth and route those interrupts. Mwah. 💖🔥👑
