222On powerpc using book3s_hv mode, the vcpus are mapped onto virtual
223threads in one or more virtual CPU cores. (This is because the
224hardware requires all the hardware threads in a CPU core to be in the
225same partition.) The KVM_CAP_PPC_SMT capability indicates the number
226of vcpus per virtual core (vcore). The vcore id is obtained by
227dividing the vcpu id by the number of vcpus per vcore. The vcpus in a
228given vcore will always be in the same physical core as each other
229(though that might be a different physical core from time to time).
230Userspace can control the threading (SMT) mode of the guest by its
231allocation of vcpu ids. For example, if userspace wants
232single-threaded guest vcpus, it should make all vcpu ids be a multiple
233of the number of vcpus per vcore.
