Thanks to Felix for bringing this to my attention. Obviously there was
already a safety net for feeding progressbars and graphs... and while
this makes for a good coding practice it's not a big deal. We have
widgets of type textbox for one, and a lot of string concatenation
happens. Strings are formatted, markup is applied...
It also won't break anymore when voltage support is missing since it
happens so often. But there are no handlers for the frequency or
governors - if you don't have those what the hell are you doing with
this widget anyway?
The cpufreq widget supplements the cpu widget. It returns the current
CPU scaling frequency (in MHz and GHz), voltage (in mV and V) and
governor information for a requested CPU. If supported by the
processor and correct kernel modules are loaded.
