[Qemu-devel] [PATCH v5 03/12] target-i386: Disable VME by default with TCG |
Date: |

VME is already disabled automatically when using TCG. So, instead
of pretending it is there when reporting CPU model data on
query-cpu-* QMP commands (making every CPU model to be reported
as not runnable), we can disable it by default on all CPU models
when using TCG.
Do that by adding a tcg_default_props array that will work like
kvm_default_props.
