Design

There are three usecases that I want to support here

1. High level interface to software tooling allowing all syseng diagnostics collectable via tt-smi and tt-mod to be readback and interacted with as a library.
   • This will only be a high level interface so it will only support pci connections and remote connections via pci
   • Will ignore all details of using communication channels such as which pci tlb or which erisc core to use.
2. General chip discovery and init, replacing create-ethernet-map and tt-smi wait. We'll probably also add the ability to issue resets.
3. Low level syseng-only debug capability (via pyluwen)
   • To avoid needing to have multiple in flight stacks you will be able to drop down a level and access the implemented communication apis directly. Practically this means direct access to the types defined in luwen-ref. This means that you can modify pci tlbs and erisc cores being used or cut out the middle man entirely and issue raw calls.
