msubu_func(9)

📦 version 7.3.1, in nixpkgs unstable

💅 msubu_func(9) — like, the Kernel API Manual girlies know ✨

Okay bestie, so this is msubu_func, a little function from the Kernel API Manual (yes, that's the manual section 9 vibe, kernel-level, very main character of it) 🎀

🌸 NAME 🌸

msubu_func — the function that literally emulates a MSUBU instruction. That's it, that's the whole job. Slay 💅

🦋 SYNOPSIS 🦋

int msubu_func (struct pt_regs *regs , u32 ir );

✨ ARGUMENTS ✨

  • regs — the process register set 🫶 like, all the registers for the process, handed over so the emulation has somewhere to work.
  • ir — the instruction 🔥 the actual instruction being dealt with, typed as a u32.

💖 DESCRIPTION 💖

It returns 0 because it always succeeds. No cap. Every single time. Zero drama, zero failure, just 0 and vibes 😌✨

👑 SEE ALSO 👑

Pop off, cross-reference section, you're iconic. Everything here lives around the kernel file ./arch/mips/kernel/mips-r2-to-r6-emul.c:

💀 Friendly reminder: the only thing this one does is return 0. If you were bracing for an error code, breathe — there isn't one. 🙈

Okay that's the whole page, mwah 💜 This little star comes from the kernel source spot ./arch/mips/kernel and it's dated October 2026 — go off, calendar icon 🗓️✨ bye bestie, iykyk 🌈💖
