m/p/kexec: add auxiliary EFI handling

This makes kexec do auxiliary handling related to EFI. If a system is
booted using EFI and has an ACPI Root System Description Pointer (RDSP)
i.e. just about every modern system, the pointer to that structure needs
to be passed to the kexec'ed kernel on its command line.
Otherwise various EFI-related functionality breaks, like accessing
EFI variables which causes a kernel crash.

Logically I think this functionality belongs to kexec as callers
shouldn't need to be aware of kexec specifics and every caller
potentially running on EFI needs this functionality.

Monogon Monorepo

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!

Environment

Our build environment requires a working Podman binary (your distribution should have one).

Usage

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)

IntelliJ

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.

Metropolis

Run a single node cluster

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 //...
