At least a lot of the register handling, but that will always be somewhat architecture specific. > ... , so perhaps it'd be easier to start with the seccomp-based model: > > https://patchwork.ozlabs.org/project/linux-um/list/?series=329466 > > But that's not really done yet either. Yes, though I have quite some updates locally that solve the security issues (i.e. prevent host syscalls from userspace). So, it does need rebasing and I am sure bugfixes, but I think it is getting into a pretty good shape overall. Either way, the old patchset will give you a good idea about how it all works, the changes are mostly in the details. I am happy to push out a new version sooner rather than later if it might help with any efforts on your side.
