centrino_init(9)

✨ NAME ✨

centrino_init — initializes the Enhanced SpeedStep CPUFreq driver. And yes bestie, this is the centrino_init(9) page, so buckle up for some main character energy 💅

🎀 SYNOPSIS 🎀

int centrino_init (void );

🦋 ARGUMENTS 🦋

• void — no arguments. Literally none. Not a single one. Slay.

💖 DESCRIPTION 💖

Okay so centrino_init initializes the Enhanced SpeedStep support. That’s the vibe. It returns stuff, and every return matters:

• -ENODEV — on unsupported devices.
• -ENOENT — if there’s no voltage table for this particular CPU model.
• -EINVAL — on problems during initiatization.
• zero — on success. Periodt.

This driver is quite picky. Not only does the CPU have to advertise the "est" flag in the cpuid capability flags, we look for a specific CPU model and stepping, and we need to have the exact model name in our voltage tables. That is, be paranoid about not releasing someone’s valuable magic smoke 🔥 no cap.

Bestie, this is the “do not let the magic smoke out” part. The page literally says be paranoid, so we’re being paranoid 🫶
