💖 DESCRIPTION 💖

The viasio driver provides support for the VIA VT1211 LPC Super I/O IC. Right now, the hardware monitoring and watchdog timer functions are supported. Slay. 🔥

The hardware monitor gives you hardware monitoring capabilities to be used with the sysctl(8) interface. Here’s the sensor lineup, no cap:

• TEMP1 — units uK — typical use: Pentium II type thermal diode
• UCH1 — units uK or uV DC — typical use: CPU temperature
• UCH2 — units uK or uV DC — typical use: System temperature
• UCH3 — units uK or uV DC — typical use: CPU core voltage
• UCH4 — units uK or uV DC — typical use: +5V
• UCH5 — units uK or uV DC — typical use: +12V
• +3.3V — units uV — typical use: Internal +3.3V
• FAN1 — units RPM — typical use: Fan tachometer
• FAN2 — units RPM — typical use: Fan tachometer

If the hardware monitor is not enabled by firmware, the driver can try to enable it if value 0x0001 is present in the flags.

⚠️ Note that enabling the hardware monitor can lead to unexpected results. Like, fr fr, be aware.

The watchdog timer provides a standard watchdog(4) interface. If the watchdog timer is not enabled by firmware, the driver can try to enable it if value 0x0002 is present in the flags. 🫶
