| * kernel: fix passthru.testsAtemu2023-08-06
| | | | | | | | | | | | | | | | | | https://github.com/NixOS/nixpkgs/pull/191540 indirectly broke kernel passthru.tests; calling the testsForLinuxPackages and testsForKernel functions with some args intended for some other exposed test-internal function. Organise the passed-through functions under `passthru` to prevent this from happening.

* linux: default stdenv.hostPlatform.linux-kernelAlyssa Ross2023-05-22
| | | | | | | | | | | | With this change, we can do a reasonable default build of Linux for configurations that do not have a corresponding platforms.nix entry, and where the user has not explicitly specified the linux-kernel values. This allows us to do best effort builds for obscure architectures (I tested a build for s390x). The platformName binding has not been used since 70cb7050f5c ("Trying to make the linux kernels also cross-build."), so I removed it.
* linuxManualConfig: don't ignore cross config errorsAlyssa Ross2023-05-19
| | | | | All "pc" kernel configurations in lib.systems.examples build fine without errors when cross compiling.
* nixos/doc: update custom kernel instructionsNaïm Favier2022-12-22
| | | | | | | Document the `linux.override` way first, then `linuxManualConfig`. Add a `linux.configEnv` passthru attribute for quickly getting a `make nconfig`-ready shell.
* linuxManualConfig: don't require lib and stdenv argumentsNaïm Favier2022-12-22
| | | | | | | Reverts https://github.com/NixOS/nixpkgs/commit/7c7c83e2335c3aa6f26a4f9c905c49c430b5be09 which was only needed for the minimal-kernel.nix test module and clutters the call site. stdenv can still be overridden with `linuxManualConfig.override { stdenv = ...; }`.

* linux: provide pahole when configuringK9002022-08-02
| | | | | | | | The kernel checks the version of pahole at configuration time to know if it supports features like split BTFs. If pahole doesn't exist, all of that gets disabled in the config file, so the kernel ends up built without split BTFs, despite having a working pahole for the actual build.

* linux: make sure that `src`/`version` actually refer to the declaring fileMaximilian Bosch2021-11-01
| | | | | | | | | | | | | | With this change it's ensured that `builtins.unsafeGetAttrPos` actually points to `<nixpkgs/pkgs/os-specific/linux/kernel/linux-x.y.nix>` when retrieving the position of `src` or `version` of `linuxPackages.kernel`. This is relevant to make sure that ofborg pinging maintainers on kernel updates actually works[1]. While the underlying issue should be fixed in ofborg or Nix itself, this is IMHO a pragmatic change to ensure that all kernel maintainers are automatically notified on updates.

* kernel/generic: add kernelTests automaticallyAtemu2021-08-23
| | | | | | | | Unfortunately, there seems to be no way of referencing an overridable version of the package you're in, so it had to be stubed to work at all. This isn't important for our current, very basic kernel nixosTests but might become important when we add more sophisticated ones.

* | buildLinux: pass buildPackages to linuxManualConfigBernardo Meurer2021-07-17
| | | | | | | | | | | | | | | | | | | | We should be using the _same_ buildPackages when we generate the configuration (which happens in buildLinux) as when we actually build the kernel (which happens in linuxManualConfig). This change enforces that when we callPackage `manual-config.nix` we pass on whatever `buildPackages` that `buildLinux` itself was called with.
* | buildLinux: preserve structuredExtraConfig and extraMakeFlags in passthruBernardo Meurer2021-07-13
| | | | | | | | | | This allows users to override custom kernel packages (e.g. linux_xanmod) that set their own structuredExtraConfig with ease.
* | buildLinux: take and propagate extraMakeFlagsBernardo Meurer2021-07-12
| | | | | | | | | | | | | | This is just for practicity, as it allows users of buildLinux to pass along extra flags they need in the kernel's make invocation. This makes, for example, supporting LLVM _much_ easier, and could enable us in the future to provide clang-built kernels.
* | buildLinux: apply hostPlatform.linux-kernel.makeFlags to generate-config.plBernardo Meurer2021-07-12
| | | | | | | | | | | | | | | | | | | | | | | | This enforces that the configuration generated will obey any/all flags set in the platform/stdenv configuration. This is crucial, for example, if you'd like to build a kernel using clang. Without this patch, anything you set in `stdenv.hostPlatform.linux-kernel.makeFlags` is wholly ignored during config generation, causing (for example) any changes in the desired toolchain (e.g. `LLVM`, `LLVM_IAS`) to not be reflected in the generated config, and for the subsequent build to fail.

* | linux: remove remnants of grsecurityAlyssa Ross2021-04-06
| | | | | | | | | | | | | | | | | | | | Nixpkgs hasn't supported grsecurity kernels since 2017, so unless anybody is manually enabling the grsecurity feature to make these small kernel tweaks this is dead code. This means we don't actually support any "features" in the kernel common-config any more, but I've left the argument there because it's conceivable we could have some again in future.
* | linux: remove xen_dom0 feature entirelyAlyssa Ross2021-04-05
|/ | | | | | | Xen is now enabled unconditionally on kernels that support it, so the xen_dom0 feature doesn't do anything. The isXen attribute will now produce a deprecation warning and unconditionally return true. Passing in a custom value for isXen is no longer supported.

* lib: Clean up how linux and gcc config is specifiedJohn Ericson2021-01-21
| | | | | | | | | | | | | | | | 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.

* treewide: add warning comment to “boot” packagesMatthew Bauer2020-07-31
| | | | | | | | | | | | | | | This adds a warning to the top of each “boot” package that reads: Note: this package is used for bootstrapping fetchurl, and thus cannot use fetchpatch! All mutable patches (generated by GitHub or cgit) that are needed here should be included directly in Nixpkgs as files. This makes it clear to maintainer that they may need to treat this package a little differently than others. Importantly, we can’t use fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale hashes, we need to include patches that are subject to changing overtime (for instance, gitweb’s patches contain a version number at the bottom).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This should make the composability of kernel configurations more straigthforward. - now distinguish freeform options from tristate ones - will look for a structured config in kernelPatches too one can now access the structuredConfig from a kernel via linux_test.configfile.structuredConfig in order to reinject it into another kernel, no need to rewrite the config from scratch The following merge strategies are used in case of conflict: -- freeform items must be equal or they conflict (mergeEqualOption) -- for tristate (y/m/n) entries, I use the mergeAnswer strategy which takes the best available value, "best" being defined by the user (by default "y" > "m" > "n", e.g. if one entry is both marked "y" and "n", "y" wins) -- if one item is both marked optional/mandatory, mandatory wins (mergeFalseByDefault)
