This enables report of a signature in CPUID for the TCG interpretor. Changed in v4:
- Report 0x40000001 in EAX for 0x40000000 index (Eduardo) - Report all zeros for 0x40000001 index (Eduardo) - Make code style consistent when checking limits (Eduardo) Changed in v3: - Simplify CPU limit code still further (Eduardo) Changed in v2: - Rewrite the way we bounds check / cap the CPUID index to use a flat switch, instead of nested ifs (Eduardo) - Add a 'tcg-cpuid' property to allow it to be hidden (Eduardo) - Hide the TCG signature for old machine types - Force code to a no-op if tcg_enabled() is false (Eduardo) NB, I did not introduce a general 'hypervisor-cpuid' property to obsolete the existing 'kvm=off|on' -cpu property, since it appears impossible to get the back compat semantics right, as described in a previous reply.
