Closes#376820
The issue with providing `moduleMakeFlags` via `passthru` of the kernel
package is that when this package gets overriden[1], the `moduleMakeFlags`
list still references the kernel without the overrides.
This broke e.g. kernel modules of linux-rpi4 which can be reproduced
with
nix-build --argstr system aarch64-linux -A linuxKernel.packages.linux_rpi4.zfs_2_3
This used to break with
Error: modDirVersion 6.6.51 specified in the Nix expression is wrong, it should be: 6.6.51-v8
since KBUILD_OUTPUT referenced the kernel without the changes from
`overrideDerivation` that also changes the `modDirVersion`.
The new approach is to add the build flags right into
`linuxKernel.packages.linux_X_Y`: that way we don't need any hacks to
update `moduleMakeFlags` when the derivation with the passthru gets
overridden.
By using the fixpoint of the package-set, the `kernelModuleMakeFlags`
list is correctly updated. E.g. given
with import ./. {};
linuxKernel.packages.linux_6_6.extend (self: super: {
kernel = super.kernel.overrideAttrs (_: {
name = "linux-snens";
});
})
the `makeFlags` is correctly updated:
$ nix-instantiate snenskek.nix -A zfs_2_3.makeFlags --eval --strict
[ "ARCH=x86_64" "CROSS_COMPILE=" "KBUILD_OUTPUT=/nix/store/gsp68549k1aqbwxwczpgw67w5jjn4shw-linux-snens-dev/lib/modules/6.6.74/build" ]
[1] E.g. `linux-rpi4`.
After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.
This commit was automatically created and can be verified using
nix-build a08b3a4d19.tar.gz \
--argstr baseRev b32a094368

Like with other morrownr modules, the 8821cu repo now links to
the 8821cu-20210118 repository as the place to get the driver code. I
kept the homepage as 8821cu though, because in future if a new version
of the driver is created, that's where the link will be posted.
Fixes the build with Linux 5.17.
