Hi Sasha, For future questions, please cc the lm-sensors mailing list since other people might be interested as well. > I compiled the driver and successfully installed the module on my > distribution (TimeSys 2.6.17) .

I'm not familiar with TimeSys but from the name I'm assuming your're running a 2.6.17 kernel. The official vt1211 driver is not part of this kernel, it got added later with 2.6.19. Are you using Lars Ekmans' driver? If so, you should switch to 2.6.19 or later and use the official vt1211 driver that comes with the kernel. Like all hwmon drivers, the vt1211 driver creates a bunch of sysfs files which are used to exchange data between the driver and user-space processes. After loading the official driver, check /sys/class/hwmon/vt1211. It contains a bunch of files that you can access using regular read() and write() file operations to retrieve data from the driver (like temps and fan RPMs) or write data to the driver (like thermal thresholds). Please check Documentation/hwmon/sysfs-interface and vt1211 for an explanation of how to interpret the various files and their content. The standard way is to use a tool called 'sensors' which is part of the lm-sensors package. It reads these files, manipulates the data according to some rules specified in /etc/sensors.conf and displays them.

VIA's tool doesn't work with the 2.6.19 vt1211 driver, it is tailored toward the old unofficial driver. ...juerg > Thanks for the help. > > -- sasha >
