mipsr2_decoder(9)

💅 mipsr2_decoder(9) — like, the Kernel API Manual entry bestie 🎀

Okay so, welcome to the <pink>Kernel API Manual</pink>, babe. Today's main character is mipsr2_decoder(9) — yes, that's the manpage name, and yes, she's iconic.

✨ NAME ✨

mipsr2_decoder — Decode and emulate a MIPS R2 instruction 🦋

Like, she takes a MIPS R2 instruction and does the whole decode-and-emulate thing. That's her job. That's her moment. Periodt.

---

🌸 SYNOPSIS 🌸

Girl, here's the signature, copy it exactly, no cap:

int mipsr2_decoder (struct pt_regs *regs , u32 inst , unsigned long
*fcr31 );

Yes bestie, that line break is on purpose. Keep it. 🙈

---

💖 ARGUMENTS 💖

Three args, three vibes, let's go:

• regs — Process register set. Like, all the registers for the process, handed to you on a silver platter 🫶
• inst — Instruction to decode and emulate. This is THE instruction, the one and only, the reason we're all here 👑
• fcr31 — Floating Point Control and Status Register Cause bits returned. Yup, the Cause bits come back through this pointer. She's giving float-control realness, honestly 💅

This lil masterpiece came from ./arch/mips/kernel, dated October 2026, and that's the whole footer moment — mwah, love you, see you at the next manpage 🎀💖⭐
