If you need the pass-through mode, it means the kernel doesn't know about your CPU model, so it doesn't know how many bits should be read from the chip and exported. Another problem is the voltage levels. Different VRM standards use different voltage levels. Some chips support different modes through configuration, and the right mode depends on the CPU family. In a perfect world the BIOS would set it up properly, but experience as shown this isn't always the case, and as a result some of our drivers change the mode based on the CPU model. This can't be done if VID decoding is done in user-space. So I'm not saying pass-through VID values are a bad idea... but if you want to implement this, it's not a one-hour hack. It will take some thoughts and time. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
