Intel Granite Rapids systems use domains 0-2 for CPUs, and 3-4 for IO, with cluster always 0.

For the "--show" and "--hide" options, use "UncMHz" to operate on all UMHz*.* as a group.

.SH TOO MUCH INFORMATION EXAMPLE

By default, turbostat dumps all possible information -- a system configuration header, followed by columns for all counters.
