These two packages don't have a lib/firmware directory, so putting
them in hardware.firmware has no effect. This will become a hard
error once firmware compression is implemented.
(In the case of Linux, the firmware was all moved to linux-firmware.)
We can't assume that DRI card minor is the same as NVidia GPU device minor,
because some DRI minors could be taken by GPUs of other vendors.
Fixes#87788, #98942.
The current type for the busId options are too relaxed, a stricter
constraint should be imposed to guard against typos which result
in Xorg unable to start.
This commit restricts the type to adhere to the B/D/F notation[1] for
addressing devices as expected by the module option.

The new option (disabled by default) pulls in the experimental sensor
calibration files for the Facetime HD camera. These will also be pulled
in by hardware.enableAllFirmware.
For displays with high pixel density, there is no need to do subpixel
anti-aliasing (which is the default) – grayscale antialiasing is enough.
In terms of fontconfig, we keep antialiasing on, but tell it not to play
any RGB tricks.
GDM enables Wayland on supported platforms automatically (see ${gnome.gdm}/lib/udev/rules.d/61-gdm.rules), so we removed the `gdm.nvidiaWayland` option.
You will still need `hardware.nvidia.modesetting.enable = true;` with `nvidia` driver, though.
The Intel SGX DCAP driver makes the SGX application enclave device and
the SGX provisioning enclave available below the path `/dev/sgx/`. Since
Linux 5.11, a derivation of the DCAP driver is part of the kernel and
available through the X86_SGX config option; NixOS enables this option
by default.
In contrast to the out-of-tree DCAP driver, the in-tree SGX driver uses
a flat hierarchy for the SGX devices resulting in the paths
`/dev/sgx_enclave` for the application enclave device and
`/dev/sgx_provison` for the provisioning enclave device.
As of this commit, even the latest version of the Intel SGX PSW
libraries still tries to open the (legacy) DCAP paths only. This means
that SGX software currently cannot find the required SGX devices even if
the system actually supports SGX through the in-tree driver. Intel wants
to change this behavior in an upcoming release of intel/linux-sgx.
Having said that, SGX software assuming the SGX devices below
`/dev/sgx/` will prevail. Therefore, this commit introduces the NixOS
configuration option `hardware.cpu.intel.sgx.enableDcapCompat` which
creates the necessary symlinks to support existing SGX software. The
option defaults to true as it is currently the only way to support SGX
software. Also, enabling the SGX AESM service enables the option.
The permissions of the devices `/dev/sgx_enclave` and
`/dev/sgx_provison` remain the same, i.e., are not affected regardless
of having the new option enabled or not.
This renames our `firmwareLinuxNonfree` package to `linux-firmware`.
There is prior art for this in multiple other distros[1][2][3].
Besides making the package more discoverable by those searching for the
usual name, this also brings it in-line with the `kebab-case` we
normally see in `nixpkgs` pnames, and removes the `Nonfree` information
from the name, which I consider redundant given it's present in
`meta.license`.
The corresponding alias has been added, so this shouldn't break
anything.

This patch fixes a bug caused by an incorrect reference to
'nvidiaSettings' rather than 'cfg.nvidiaSettings'. The bug caused
the system to not build when using the nvidia drivers.
Tested on my local machine.
For security reasons, and generally, it is best to create a more fine
grained group than plugdev. This way users that wish to tweak razer
devices don't have access to the entire plugdev group's permissions.
This is of course a breaking change.

fixes#57053
fixes "Direct firmware load for regulatory.db failed with error -2"
in dmesg
Note that all kernels on unstable are newer that 4.15, which is required
for this to work.
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.
I just got an Xbox One controller and I wasn't satisfied with the xpad
driver that ships with the Linux kernel
xpadneo supports more features and fixes problems with

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.
