💖 NAME 💖

finsio — the Fintek LPC Super I/O driver. that's the name, that's the vibe.

🎀 SYNOPSIS 🎀

finsio0 at isa? port 0x4e

💅 DESCRIPTION 💅

the finsio driver is here to support the F71805F, F71806F, F71862FG, F71872, F71882 and F71883 LPC Super I/O chips. iconic chip lineup, no cap.

Only the Hardware Monitor device is supported, and it's the one that lets you monitor the sensors through the envsys(4) API. that's the whole supported-device situation, bestie.

the finsio Super I/O Hardware Monitor supports 15 sensors (this depends on the chip ID). here's the full sensor lineup, and yes we're listing every single one:

• IN0 — units: uV DC; typical use: Internal 3.3Vcc
• IN1 — units: uV DC; typical use: Memory Vtt
• IN2 — units: uV DC; typical use: RAM Vcc
• IN3 — units: uV DC; typical use: Chipset V
• IN4 — units: uV DC; typical use: +5V
• IN5 — units: uV DC; typical use: +12V
• IN6 — units: uV DC; typical use: Vcc 1.5V
• IN7 — units: uV DC; typical use: Vcore
• IN8 — units: uV DC; typical use: Vsb
• IN9 — units: uV DC; typical use: Vbat (optional)
• Temp1 — units: uK; typical use: CPU Temperature
• Temp2 — units: uK; typical use: Motherboard Temperature
• Temp3 — units: uK; typical use: (undefined)
• Fan0 — units: RPM; typical use: CPU Fan
• Fan1 — units: RPM; typical use: User Fan1
• Fan2 — units: RPM; typical use: User Fan2
