Description

Features that we would like to see

Required (we almost certainly want them)

• Automatically determining the right Rust version to use.
  • The kernel currently only supports one Rust version at a time. It would be great to support several Rust versions at a time so that the right one is picked to compile a given kernel.
  • Apparently hard to do in the legacy system, but perhaps it is possible to have a single "universal" image with a rustc binary that redirects to the right one. In other words, for the purposes of KernelCI, Rust would have a single toolchain version.
• Enable KUnit tests.
  • i.e. CONFIG_RUST_KERNEL_DOCTESTS.

Nice to have (not critical, we could workaround if needed, etc.)

Low priority (we will likely not use them in the end)

Done (stabilized, fixed, not needed anymore, etc.)
