KVM: PPC: Book3S HV: XIVE: Show detailed configuration in debug output
This is useful to track allocation of the HW resources on per guest basis. Making sure IPIs are local to the chip of the vCPUs reduces rerouting between interrupt controllers and gives better performance in case of pinning. Checking the distribution of VP structures on the chips also helps in reducing PowerBUS traffic.
