222 | On powerpc using book3s_hv mode, the vcpus are mapped onto virtual | ||
223 | threads in one or more virtual CPU cores. (This is because the | ||
224 | hardware requires all the hardware threads in a CPU core to be in the | ||
225 | same partition.) The KVM_CAP_PPC_SMT capability indicates the number | ||
226 | of vcpus per virtual core (vcore). The vcore id is obtained by | ||
227 | dividing the vcpu id by the number of vcpus per vcore. The vcpus in a | ||
228 | given 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). | ||
230 | Userspace can control the threading (SMT) mode of the guest by its | ||
