gnidorah 90deca3a0c nixos-generate-config: detect CPU governor
* cpu-freq: Try powersave if ondemand is not available

* Revert "cpu-freq: Try powersave if ondemand is not available"

This reverts commit 4dc56db37e32dcfecd667ebbf88263e47b296097.
Consult available scaling governors; for freshly generated configs, this provides a better experience than relying on a default that might not work everywhere.

aaron levin c3e0107201 Remove default scsiLinkPolicy 2015-12-17 16:40:35 +01:00
aaron levin 3b3be7a74b link_power_policy_management default to max_performance
The kernel default for `link_power_management_policy` is `"max_performance"`.
This commit:
f169f60575
set the NixOS default to `"min_performance"`.

This issue (https://github.com/NixOS/nixpkgs/issues/11276) details my long
journey to discover this after several file system failures incorrectly
attributed to `TRIM` and `NCQ` settings.

I think we should use the kernel default of `"max_performance"` to assure
the best experience for new users with SSDs and to conform to the defaults of
the kernel and other distros.

Thomas Strobel d5604f0b22 power management: restart post-resume.target on resume
Trigger a restart of the post-resume.target on resume.
That allows other systemd services to receive the restart signal
after resume by becoming 'partOf' the post-resume.target.

nixos/manual: Use literalExample when feasible.
Should bring most of the examples into a better consistency regarding
syntactic representation in the manual.

Thanks to @devhell for reporting.

William A. Kennington III dd209e901c cpu-freq: Use cpupower instead of cpufrequtils
Additionally, put the powersave utility in charge of loading the
cpufrequency modules based on the governor specified in the
configuration.

Eelco Dolstra 29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

ambrop7@gmail.com 49768ca8ff power-management: Don't enable acpid.
Running acpid along with systemd will cause double handling of acpi events.
