In the process of developing nueDynamicClock, I developed a need to monitor the other clock speeds on MSM7xxxA based devices. The MSM7xxxA actually has a number of clocks which control internal functions such as USB, Display, I2C, etc… I think there are maybe 40+ different clocks in total, which is pretty impressive. Anyway, nueClockViewer will display in real time these clock speeds – except for the applications processor (use nueClockControl for that). The meaning of the index differs from device to device- I think the htc-linux wiki has a description of some of the clocks. Probably only useful for developers, but I figured someone might find it useful.
