Newer ThinkPads have a new name for the Trackpoint - "TPPS/2 Elan TrackPoint".
Having the "[...] IBM Trackpoint" as default caused some weird
side-effects on my machine (e.g. stopped the trackpoint working after a
suspend) with the wrong name. Although this is mentioned in the option's
description[1], I think that this should be declared explicitly here.
As soon, as we supported newer models as well[2], we should probably
move this into its own common profile.

Most trackpoint users I know use the middle-button to have some
scrolling functionality. So I think that for ThinkPads at least we
should have this enabled by default if the trackpoint shall be used.
This will run TRIM once a week using a systemd timer. Running TRIM regularly
will improves the performance and increases the SSDs lifespan. Since it is based
on the utillinux no additional package is required.
Prior to this commit, an apu's boot would go through stages of varying visibility:
1. BIOS: exposed to serial
2. GRUB: not exposed to serial
3. Linux: exposed to serial
This commit changes (2) to be visible over serial, so the entire boot is visible over serial.
Tested on nixos 18.09 on a https://www.pcengines.ch/apu1d.htm
This is pretty much a copy of XPS 9370, without kaby-laky and the throttle bug. I was getting lockups with the kaby-laky changes and the throttle bug did not seem to have an impact either way.
nix-env picked up `default.nix`, which contained our hardware profiles.
This is not only cpu-intensive to evaluate but also fails because
it does some import-from-derivation.
By moving default.nix to release.nix it should be no longer loaded
With UEFI >= 1.30, there's an explicit option to enable S3 power management.
Once this is selected, S3 is enabled and "deep" is selected as the default
/sys/power/mem_sleep value without requiring any kernel boot parameters.
This adds basic support for the Thinkpad T440s, based on the work done for the T440p. The expression enables:
- microcode updates
- trackpoint support
- kernel module for battery level management
