the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
This should be a significant disk space saving for most NixOS
installations. This method is a bit more complicated than doing it in
the postInstall for the firmware derivations, but this way it's
automatic, so each firmware package doesn't have to separately
implement its compression.
Currently, only xz compression is supported, but it's likely that
future versions of Linux will additionally support zstd, so I've
written the code in such a way that it would be very easy to implement
zstd compression for those kernels when they arrive, falling back to
xz for older (current) kernels.
I chose the highest possible level of compression (xz -9) because even
at this level, decompression time is negligible. Here's how long it took
to decompress every firmware file my laptop uses:
i915/kbl_dmc_ver1_04.bin 2ms
regulatory.db 4ms
regulatory.db.p7s 3ms
iwlwifi-7265D-29.ucode 62ms
9d71-GOOGLE-EVEMAX-0-tplg.bin 22ms
intel/dsp_fw_kbl.bin 65ms
dsp_lib_dsm_core_spt_release.bin 6ms
intel/ibt-hw-37.8.10-fw-22.50.19.14.f.bseq 7ms
And since booting NixOS is a parallel process, it's unlikely (but
difficult to measure) that the time to user interaction was held up at
all by most of these.
Fixes (partially?) #148197
First, add the builtin udev rules to /etc/udev/rules.d so they are used.
Then, add all networkd .link units to the initrd. This is done in the
old stage 1 as well so I assume this is needed even when networkd is not
used. I assume this is for things like changing the MAC address.
Also limit the number of udev/lib binaries that is put into the initrd
because the old initrd doesn't use all units either.
One of the valid values for the fan speed is "level disengaged",
however, it is represented as "level disengage" and does not match
what thinkfan expects.
adds defaultText for all options that use `cfg.*` values in their
defaults, but only for interpolations with no extra processing (other
than toString where necessary)
NixOS should be able to support the Nintendo Switch Pro controller for
steam and non-steam at the same time. Currently there are two mutually
exclusive ways to support the Pro Controller: Steam and `hid-nintendo`.
Unfortunately these don't work together, but there's a workaround in
newer versions of `joycond` (described [here](https://wiki.archlinux.org/title/Gamepad#Using_hid-nintendo_pro_controller_with_Steam_Games_(with_joycond))). To use this
workaround `hid-nintendo` and `joycond` need to be updated, and the
systemd and udev configuration needs to be made available in NixOS.
The attributes got renamed in PR #126440 and in some places this caused
evaluation errors, e.g. the tarball job was saying (locally)
> attribute 'alsaUtils' missing, at /build/source/nixos/modules/services/audio/alsa.nix:6:4
and I suspect that trunk-combined jobset's failure to evaluate was also caused.
set a group and user for the service
remove default null config
it's required, now it throws an error pointing to the option
set myself (module author) as maintainer
Upstream has been providing a very thoroughly designed set of systemd units,
udev and polkit rules. With these the brltty daemon is activated
asynchronously via udev, runs as a dedicated user with runtime and state
directories set up using systemd-tmpfiles.
This is much better than the current unit, which runs a single instance
as root and pulls in systemd-udev-settle to wait for the hardware.
- Actually run tcsd as tss/tss
- Install a udev rule to set /dev/tpm* permissions
- Remove systemd-udev-settle dependency, use dev-tpm0.device instead
- Use systemd-tmpfiles to set up the state directory
- Add documentation URI to tcsd.service
This module cannot be easily tested with a NixOS test due to the TPM
dependency. Technically, one could be emulated using swtpm[1], but this
is not packaged in Nixpkgs. If you computer has a real TPM you can do a
passthrough in Qemu, but this requires running the VM as root and of
course it's not determinstic:
$ nix build -f nixos vm --arg configuration '
{
virtualisation.qemu.options = [
"-tpmdev passthrough,id=tpm0,path=/dev/tpm0,cancel-path=/sys/class/tpm/tpm0/cancel"
"-device tpm-tis,tpmdev=tpm0"
];
users.users.root.hashedPassword = "";
services.tcsd.enable = true;
}'
After starting the VM, log in as root, you can check the service has
started with `systemctl status tcsd`.

I'm sorry guys.
Thinkfan underwent some major changes and the config file
is now based on YAML. This commit contains a number of changes:
- rewrite the module to output the new format;
- add a `settings` option, following RFC 0042[1];
- add fancy type-checking for the most critical options
- use upstream systemd units (which fix the resume issue)

There was some issues with the fallback to passive mode on 2.3, but on
2.4 adaptive mode is always enabled upstream and thermald will fallback
to passive if necessary.

These were broken since 2016:
f0367da7d1
since StartLimitIntervalSec got moved into [Unit] from [Service].
StartLimitBurst has also been moved accordingly, so let's fix that one
too.
NixOS systems have been producing logs such as:
/nix/store/wf98r55aszi1bkmln1lvdbp7znsfr70i-unit-caddy.service/caddy.service:31:
Unknown key name 'StartLimitIntervalSec' in section 'Service', ignoring.
I have also removed some unnecessary duplication in units disabling
rate limiting since setting either interval or burst to zero disables it
(ad16158c10/src/basic/ratelimit.c (L16))
We no longer escape the flags because the power limit flags want two arguments
If we escaped them, we'd only get one argument with an escaped space in it.
Undervolt's flags don't have anything in them that would need to be escaped, so
that shouldn't break anything
We need to keep the passthru.filesInstalledToEtc and passthru.defaultBlacklistedPlugins in sync with the package contents so let's add a test to enforce that.
udev gained native support to handle FIDO security tokens, so we don't
need a module which only added the now obsolete udev rules.
Fixes: https://github.com/NixOS/nixpkgs/issues/76482
The default `undervolt` package does not accept floating point numbers for any of its numeric
arguments. This also mentions in what units are the values expressed.
https://github.com/NixOS/nixpkgs/pull/88492 flipped some references to
systemctl from config.systemd.package to /run/current-system/systemd/,
which udevRules obviously isn't able resolve.
If we encounter such references, replace them with
config.systemd.package before doing the check.
invalid test was introduced in 297d1598ef
and it is disabled in the shipped daemon.conf.
I forgot to reflect that in the module, which caused the daemon to print the following on start-up:
FuEngine invalid has incorrect built version invalid
and the command to warn:
WARNING: The daemon has loaded 3rd party code and is no longer supported by the upstream developers!
To reduce the change of this happening in the future, I moved the list of default disabled plug-ins to the package expression.
I also set the value of the NixOS module option in the config section of the module instead of the default value used previously,
which will allow users to not care about these plug-ins.
Aligned systemd service config with the definition in the upstream repo:
https://github.com/Irqbalance/irqbalance/blob/master/misc/irqbalance.service#L7.
Other than adding some level of sandboxing it also fixes the "Daemon
couldn't be bound to the file-based socket." warning reported on
irqbalance startup due to the fact that the "/run/irqbalance" directory
didn't exist. The "RuntimeDirectory" property makes sure it gets
created. The aforementioned warning didn't cause any problems I could
spot though.
I have verified that both `irqbalance` as well as `irqbalance-ui` work
fine with this new systemd service config.
In the process of making UPower.conf customizable (#73968), it came up
that UPower doesn't load its config from /etc by default.
The UPower derivation is modified to make it load its config from /etc
at runtime, but still install the default config to its nix store path
as before.
The UPower module is modified to put the config in /etc.
- Add services.hardware.bluetooth.config option
- Use lib.generators.toINI with both config and extraConfig options
hardware/bluetooth: a couple suggestions

* lm_sensors: add fancontrol module + nixos test
fancontrol is a small script that checks temperature sensors and adapts
fan speeds accordingly. It reads a text config file that can be
auto-generated by running the pwmconfig wizard on the live system.
Since https://github.com/NixOS/nixpkgs/pull/61321, local-fs.target is
part of sysinit.target again, meaning units without
DefaultDependencies=no will automatically depend on it, and the manual
set dependencies can be dropped.
The udev rules we are shipping no longer work with systemd v242 and were
remove upstream some time ago. It seems like the entire renaming is now
done in C and not in the udev rules.
Don't add the testing "webcam" device,
which is unexpected to see when querying
what devices fwupd believes exist :).
Won't change behavior for anyone defining
the blacklistPlugin option already,
but doesn't seem worth making more complicated.
This adds a NixOS option for setting the CPU max and min frequencies
with `cpufreq`. The two options that have been added are:
- `powerManagement.cpufreq.max`
- `powerManagement.cpufreq.min`
It also adds an alias to the `powerManagement.cpuFreqGovernor` option as
`powerManagement.cpufreq.governor`. This updates the installer to use
the new option name. It also updates the manual with a note about
the new name.
Add package libratbag and service module ratbagd
Libratbag contains ratbagd daemon and ratbagctl cli to configure
buttons, dpi, leds, etc. of gaming mice.
Add mvnetbiz to maintainers.
thermald has two modes: zero-config and manual. Sometimes it is useful
to manually configure thermald to achieve better thermal results or to give
thermald a hand when detecting possible cooling options.
We override the ESP mount point in the config file /etc/fwupd/uefi.conf
(available since version 1.0.6), as it is set to a path in the nix store
during build time.
Tests are disabled as it needs /etc/os-release, which is not available
when building with sandboxing enabled.
This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.
Misc...
- qtikz: use libsForQt5.callPackage
