mips_cm_vp_id(9)

🌸 NAME 🌸

okay bestie, welcome to mips_cm_vp_id(9) from the Kernel API Manual — manual name folded in right here so we don’t have to do the boring header-copy thing 💅

mips_cm_vp_id — calculate the hardware VP ID for a CPU. That’s the assignment, and it ate ✨

---

✨ SYNOPSIS ✨

unsigned int mips_cm_vp_id (unsigned int cpu );

---

🫶 ARGUMENTS 🫶

• cpu — the CPU whose VP ID to calculate. That’s the whole input, no cap 🦋

---

💅 DESCRIPTION 💅

okay so picture this: hardware like the GIC uses identifiers for VPs, and those identifiers may not match the CPU numbers used by Linux. Rude? A little. Iconic? Also yes 😭

This function calculates the hardware VP identifier corresponding to a given CPU. That’s it — it’s giving “translate the Linux CPU number into the hardware’s VP ID” energy, and honestly? We love a clear little mapping function 🌈

---

🎀 RETURN 🎀

the VP ID for the CPU. Yep — that’s the return value, bestie: the VP ID for the CPU, periodt 💖
