Currently the turbostat treats ICX the same way as SKX and shares the
code among them. But one difference is that ICX does not support Package
C6 Retention, unlike SKX and CLX.
So this patch:
1. Splitting SKX and ICX in turbostat.
2. Removing Package C6 Rentention for ICX.
And after this split, it would be easier to cutomize Ice Lake Server
in turbostat in the future.

Hi,
This patch (25368d7cefcd87a94ccabcc6f9f31796607bbe4e) has affected
Sapphire Rapids support.
Specifically Pkg%pc2 and Pkg%pc6 are now missing on Sapphire Rapids
(with package C6 retention).
See below for a diff of turbostat --list output with and without 25368d7.

My guess is that the max limited package c-state exposed might be '3' rather than '2'.
Artem has previously found this issue on ICX and there is a patch:
https://patchwork.kernel.org/project/linux-pm/patch/20211004105224.3145916-1-dedekind1@gmail.com/
would you please help check if that helps?

Hi Artem, Chen,
The patch "turbostat: fix PC6 displaying on some systems" fixes the
issue on our Sapphire Rapids system.
On this system I also checked MAX_PKG_C_STATE, and it is 3.
Thanks,
