third_party/linux: improve kernel configuration These configuration changes are required to boot the Metropolis kernel via kexec on a PowerEdge R750. kexec needs to be enabled even if we're not using it as just using kexec to launch a kernel on an EFI machine requires a fixup performed only if the target kernel is built with kexec enabled. Otherwise it crashes immediately after mounting efivars by dereferencing a null pointer. bpfilter should be disabled because it needs a userspace helper (the .ko actually runs in userspacee) and we ship none of that, causing an error-level log message on every boot. Until we actually ship the required infrastructure disable it. irq_remap is required for x2apic, without it the kernel can't even boot on that platform. intel_iommu is just a drive-by enable because the AMD IOMMU is already enabled and we want the protection.

This is the main repository containing the source code for the Monogon Project.
This is pre-release software - feel free to look around, and check back later for our first release!
Our build environment requires a working Podman binary (your distribution should have one).
Spinning up: scripts/create_container.sh
Spinning down: scripts/destroy_container.sh
Running commands: scripts/run_in_container.sh <...>
Using bazel using a wrapper script: scripts/bin/bazel <...> (add to your local $PATH for convenience)
This repository is compatible with the IntelliJ Bazel plugin, which enables full autocompletion for external dependencies and generated code. All commands run inside the container, and necessary paths are mapped into the container.
The following steps are necessary:
Install Google's Bazel plugin in IntelliJ. On IntelliJ 2020.3 or later, you need to install a beta release of the plugin.
Add the absolute path to your ~/.cache/bazel-monogon folder to your idea64.vmoptions (Help → Edit Custom VM Options) and restart IntelliJ:
-Dbazel.bep.path=/home/leopold/.cache/bazel-monogon
Set "Bazel Binary Location" in Other Settings → Bazel Settings to the absolute path of scripts/bin/bazel. This is a wrapper that will execute Bazel inside the container.
Use File → Import Bazel project... to create a new project from .bazelproject.
After running the first sync, everything should now resolve in the IDE, including generated code.
Launch the node:
scripts/bin/bazel run //:launch -c dbg
Run a kubectl command:
scripts/bin/bazel run //metropolis/cli/dbg -c dbg -- kubectl describe
Run tests:
scripts/bin/bazel test -c dbg //...
