Can't really comment as I don't know which change is being discussed here. But VID is really not that interesting these days due to 1* hardware vendors no longer connecting these pins and 2* our support being somewhat limited, so you can just ignore that part. > Secondly: I assume that the correct work-flow is to make your changes in > > the it87 source code, compile the file, replace the driver and modprobe it. > > I have compiled programs before but not very frequently and nothing > > kernel-related.

As a general rule, we prefer having more testers on various kernel versions than only a few with the latest kernel. So potential testers should use whatever kernel makes their life easier. -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
