1# Zenstates provides access to a variety of CPU tunables no Ryzen processors.
2#
3# In particular, I am adding Zenstates because I need it to disable the C6
4# sleep state to stabilize wake from sleep on my Lenovo x395 system. After
5# installing Zenstates, I need a before-sleep script like so:
6#
7# before-sleep = pkgs.writeScript "before-sleep" ''
8# #!${pkgs.bash}/bin/bash
9# ${pkgs.zenstates}/bin/zenstates --c6-disable
10# '';
11#
12# ...
13#
14# systemd.services.before-sleep = {
15# description = "Jobs to run before going to sleep";
16# serviceConfig = {
17# Type = "oneshot";
18# ExecStart = "${before-sleep}";
19# };
20# wantedBy = [ "sleep.target" ];
21# before = [ "sleep.target" ];
22# };
