Thomas,

I think the ACPI C-state names are fine the way they are.

I don't understand the value proposition you have presented
to replace the C-state names with ACPI C-state types.

I think this would be extremely confusing, particularly
since it would mean that multiple states can then appear
with duplicate names.

Thus I do not recommend changing the format of the name
that we have been exporting since cpuidle went
upstream 3 years ago.

thanks,
