I wonder if we should take the issue of sysemu/system/softmmu topic into a separate series. Currently basically starting from the build system already, "softmmu", sysemu and system are treated as a single thing, and the convention from build system and directories seems to be "softmmu", while from the header files we get "sysemu/". I agree that this is not a sufficient model to account for the new feature that Richard wants to develop, I just suggest we could also consider tackling this separately, with a pass through the whole code, gathering more input in the context of a dedicated series. What do you think? Also Paolo, any comments, since softmmu is all over meson? Ciao, Claudio
