💅 speedstep_detect_chipset(9) 💅

okay bestie, welcome to the speedstep_detect_chipset(9) page from the Kernel API Manual — we are officially in Southbridge detective mode 🕵️‍♀️✨

---

🌸 NAME 🌸

speedstep_detect_chipset — detect the Southbridge which contains SpeedStep logic. fr fr, that's the whole assignment. 💖

---

✨ SYNOPSIS ✨

unsigned int speedstep_detect_chipset (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments. not a single one, bestie. 🫶

---

💖 DESCRIPTION 💖

okay so this one detects ICH2-M, ICH3-M and ICH4-M so far. 👑

The pci_dev points to the LPC bridge / PM module which contains all power-management functions. it's giving "everything power-management lives here" energy. ⚡

It returns the SPEEDSTEP_CHIPSET_-number for the detected chipset, or zero on failure. so: detected chipset → that SPEEDSTEP_CHIPSET_-number; failure → 0. that's the vibe check 💀✨
