In KVM for Book3S PPC we currently have 2 implementations. There is the PR based implementation which works on any POWER system you pass in and the super fast HV implementation which requires libre firmware (so almost nobody can use it). Currently, the two target two different machine types, with PR KVM being used for bare metal system virtualization, while the HV KVM is used to virtualize PAPR. In an effort to make things more cozy and transparent to the user, this patch set implements PAPR capabilities to the PR KVM side, so a user doesn't have to worry what the respective kernel module supports. Any machine he's virtualizing "just works".
