If you can use the Windows API, then this https://msdn.microsoft.com/en-us/library/ms683194.aspx > > Should be possible to have both info available ? > > Any idea how to obtain the other cache infos ? > > Not completely.

I have no patches, but another difference to Linux is that the CPU frequency reported is the maximum (non-turbo) frequency instead of the actual one (which could be larger or lower depending on the frequency scaling in effect). That seems to require more infrastructure, though.
