The sysfs file /sys/kernel/mm/ksm/run seems to be available as soon as
the kernel has started, so no point in waiting for udev to "settle". If
for some reason it doesn't, we let the unit fail explicitly.
This is a very simple module that installs a single udev rule.
The rule set the ownership of all /dev/i2c-* devices to a
group, "i2c" by default but can be changed. The "uaccess" tag
also makes systemd add an ACL for users with a seat[1].

The `platform` field is pointless nesting: it's just stuff that happens
to be defined together, and that should be an implementation detail.
This instead makes `linux-kernel` and `gcc` top level fields in platform
configs. They join `rustc` there [all are optional], which was put there
and not in `platform` in anticipation of a change like this.
`linux-kernel.arch` in particular also becomes `linuxArch`, to match the
other `*Arch`es.
The next step after is this to combine the *specific* machines from
`lib.systems.platforms` with `lib.systems.examples`, keeping just the
"multiplatform" ones for defaulting.
Ports an OpenWRT patch for Atheros wireless drivers (ath*) which allows
the user to change the regulatory domain code to the one which actually
applies.
All Atheros devices have a regulatory domain burned into their EEPROM.
When using a device as AP, this domain is frequently overly restrictive
when compared to the regulation which applies in the country the device
actually operates in; often, this restriction disallows IR on all
channels making it impossible to use the device as an AP at all.
This commit introduces the NixOS config option
networking.wireless.athUserRegulatoryDomain which, if enabled, applies
the patch and sets the kernel config option ATH_USER_REGD.
The original OpenWRT patch targets Linux 5.8.
- This is fetched from a different URL, so allow passing that explicitly.
- There also isn't an nvidia-persistenced or nvidia-settings release for
this version, so use 450.57 instead. Also implement passing
persistenced and settings version explicitly.

Now allows applying external overlays either in form of
.dts file, literal dts context added to store or precompiled .dtbo.
If overlays are defined, kernel device-trees are compiled with '-@'
so the .dtb files contain symbols which we can reference in our
overlays.
Since `fdtoverlay` doesn't respect `/ compatible` by itself
we query compatible strings of both `dtb` and `dtbo(verlay)`
and apply only if latter is substring of the former.
Also adds support for filtering .dtb files (as there are now nearly 1k
dtbs).

Since systemd 243, docs were already steering users towards using
`journal`:
eedaf7f322
systemd 246 will go one step further, it shows warnings for these units
during bootup, and will [automatically convert these occurences to
`journal`](f3dc6af20f):
> [ 6.955976] systemd[1]: /nix/store/hwyfgbwg804vmr92fxc1vkmqfq2k9s17-unit-display-manager.service/display-manager.service:27: Standard output type syslog is obsolete, automatically updating to journal. Please update│······················
your unit file, and consider removing the setting altogether.
So there's no point of keeping `syslog` here, and it's probably a better
idea to just not set it, due to:
> This setting defaults to the value set with DefaultStandardOutput= in
> systemd-system.conf(5), which defaults to journal.

This can be used to explicitly specify a specific dtb file, relative to
the dtb base.
Update the generic-extlinux-compatible module to make use of this option.
It's `lib.versions`, not `lib.version`. Also I'm really sure that it's
supposed to be the current version of Gutenprint, not Cups, as thats
what `lpinfo -m` says on my system.

Mesa has been supporting S3TC natively without requiring these libraries
since the S3TC patent expired in December 2017.
Due to the support of the systemd-logind API the udev rules aren't
required anymore which renders this module useless [0].
Note: brightnessctl should now require a working D-Bus setup and a valid
local logind session for this to work.

This fixes a harmless error from systemd-udevd that looks like:

A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file
The SLIM project is abandoned and their last release was in 2013.
Because of this it poses a security risk to systems, no one is working
on it or picked up maintenance. It also lacks compatibility with systemd
and logind sessions. For users, there liikely isn't anything like slim
that's as lightweight in terms of dependencies.
Invoke xrandr to actually connect the device.
Additionally, we let systemd create the logs directory and use our module loader
instead of handling it manually.
uinput needs to be added to boot.kernelModules in order for the udev
rules defined by steam to be run and set permissions correctly on
/dev/uinput.
See https://github.com/NixOS/nixpkgs/issues/70471.
Add support for custom device-tree files, and applying overlays to them.
This is useful for supporting non-discoverable hardware, such as sensors
attached to GPIO pins on a Raspberry Pi.
This was added in #19936 so that vulkan-loader finds the ICD config files. It is
not needed any more after #62869 where it was ensured that the loader looks in
/run/opengl-driver(-32)/share.
A new internal option `hardware.opengl.setLdLibraryPath` is added which controls if `LD_LIBRARY_PATH` should be set to `/run/opengl-driver(-32)/lib`. It is false by default and is meant to be set to true by any driver which requires it. If this option is false, then `opengl.nix` and `xserver.nix` will not set `LD_LIBRARY_PATH`.
Currently Mesa and NVidia drivers don't set `setLdLibraryPath` because they work with libglvnd and do not override libraries, while `amdgpu-pro`, `ati` and `parallels-guest` set it to true (the former two really need it, the last one doesn't build so is presumed to).
Additionally, the `libPath` attribute within entries of `services.xserver.drivers` is removed. This made `xserver.nix` add the driver path directly to the `LD_LIBRARY_PATH` for the display manager (including X server). Not only is it redundant when the driver is added to `hardware.opengl.package` (assuming that `hardware.opengl.enable` is true), in fact all current drivers except `ati` set it incorrectly to the package path instead of package/lib.
This removal of `LD_LIBRARY_PATH` could break certain packages using CUDA, but only those that themselves load `libcuda` or other NVidia driver libraries using `dlopen` (not if they just use `cudatoolkit`). A few have already been fixed but it is practically impossible to test all because most packages using CUDA are libraries/frameworks without a simple way to test.
Fixes#11434 if only Mesa or NVidia graphics drivers are used.
In this update:
* binaries `ckb` and `ckb-daemon` are renamed to `ckb-next` and `ckb-next-daemon`
* build system changed from qmake to cmake
* the directory searched for animation plugins no longer needs to be patched, as a result of the build system change
* modprobe patch has been bumped, since the source repository layout has changed
* the cmake scripts are quite FHS-centric and require patching to fix install locations
This adds configuration options which automate the configuration of NVIDIA Optimus using PRIME. This allows using the NVIDIA proprietary driver on Optimus laptops, in order to render using the NVIDIA GPU while outputting to displays connected only to the integrated Intel GPU. It also adds an option for enabling kernel modesetting for the NVIDIA driver (via a kernel command line flag); this is particularly useful together with Optimus/PRIME because it fixes tearing on PRIME-connected screens.
The user still needs to enable the Optimus/PRIME feature and specify the bus IDs of the Intel and NVIDIA GPUs, but this is still much easier for users and more reliable. The implementation handles both the X configuration file as well as getting display managers to run certain necessary `xrandr` commands just after X has started.
Configuration of commands run after X startup is done using a new configuration option `services.xserver.displayManager.setupCommands`. Support for this option is implemented for LightDM, GDM and SDDM; all of these have been tested with this feature including logging into a Plasma session.
Note: support of `setupCommands` for GDM is implemented by making GDM run the session executable via a wrapper; the wrapper will run the `setupCommands` before execing. This seemed like the simplest and most reliable approach, and solves running these commands both for GDM's X server and user X servers (GDM starts separate X servers for itself and user sessions). An alternative approach would be with autostart files but that seems harder to set up and less reliable.
Note that some simple features for X configuration file generation (in `xserver.nix`) are added which are used in the implementation:
- `services.xserver.extraConfig`: Allows adding arbitrary new sections. This is used to add the Device section for the Intel GPU.
- `deviceSection` and `screenSection` within `services.xserver.drivers`. This allows the nvidia configuration module to add additional contents into the `Device` and `Screen` sections of the "nvidia" driver, and not into such sections for other drivers that may be enabled.
By default, OnlyKey device (https://crp.to/p/) won't work on Linux (and,
therefore, NixOS). This is unintuitive and requires one to search for a
solution in the documentation.
This change allows one to enable OnlyKey device support directly from
their NixOS configuration.

All available options were just enabling
hardware.enableRedistributableFirmware. There were nix files without
modules which weren't referenced anywhere.
Due the recent inclusion of broadcom-bt-firmware in enableAllFirmware,
it was required to set `nixpkgs.config.allowUnfree` to obtain the full
list. To make this dependency more explicit an assertion is added and an
alternative option `enableRedistributalFirmware` is provided to only
obtain firmware with an license allowing redistribution.
This PR adds support for ```iio-sensor-proxy``` used by GNOME v3 and
others for reading data from the accelerometer, gps, compass and similar sensors
built into some relatively recent laptops.
Additionally, there is a NixOS module exposed via hardware.sensor.iio
for enabling services, udev rules and dbus services.
ckb is a driver for Corsair keyboards/mice. It also contains a graphical tool for configuring their LED backlight settings.
The driver is implemented as a userland daemon. A NixOS module is included that runs this as a systemd service.
...instead of mesa_noglu.out. Closures of systems remain unchanged,
as both are in (and the .out output is very small anyway).
This is to make sure that we use lib*GL* that aren't slowed down by grsecurity.
The pre-sleep service exits if any command fails. Unloading facetimehd
without it being loaded blocks subsequent commands from running.
Note: `modprobe -r` works a bit better when unloading unused modules,
and is preferrable to `rmmod`. However, the facetimehd module does not
support suspending. In this case, it seems preferable to forcefully
unload the module. `modprobe` does not support a `--force` flag when
removing, so we are left with `rmmod`.

This commit adds the firmware for the Intel 2200BG wireless cards for
the ipw2200 kernel module. Also it changes the
networking.enableIntel2200BGFirmware option to set it as
hardware.firmware since firmware-linux-nonfree does not contain the
appropiate firmware anymore. Also hardware.enableAllFirmware does enable
the intel2200BGFirmware now.
This is essentially what's been done for the official NixOS build slaves
and I'm using it as well for a few of my machines and my own Hydra
slaves.

Added configurations to `bumblebee` package to easy multiple monitors on Optimus
machines.
The behaviour of the default `bumblebee` package hasn't change, so this change
is backwards compatible. Users who want to connect a monitor to their discrete
card should use the package `bumblebee_display` instead.
Also added new configuration option to nixos bumblebee module:
```
hardware.bumblebee.connectDisplay = true
```
will enable the new configuration, but the default is still false.
/run/opengl-drivers should contain only libGL-related libraries, not
stuff like udev. Injecting anything into LD_LIBRARY_PATH is dangerous
because it can break applications that expect a different version of
the library.
Caused by eef9a8ac2a. Fixes#5371.
Using primusrun will work as expected in a multilib environment. Even if the initial program
executes a antoehr program of the another architecture. Assuming the program does not modify
LD_LIBRARY_PATH inappropriately.
This does not update virtualgl for seemless multilib. I was unable to get a mixed 64/32 bit
environment to work with VirtualGL. The mechanism VirtualGL uses to inject the fake GL library would
fail if both 32bit and 64 bit libraries were in the environment. Instead the bumblebee package
creates a optirun32 executable that can be used to run a 32bit executable with optimus on a 64 bit
host. This is not created if the host is 32bit.
For my usage, gaming under wine, the primusrun executable works as expected regardless of
32bit/64bit.
