Only if you were using "-cpu somethingThatHasAVX", though, no?
Yes. The same argument goes the other way around. I want to use AVX
emulation, do "allow-emulation" and suddenly I get MONITOR/MWAIT
emulation.
What about:
- letting "-cpu foo,+emulatedfeature" just work
- adding emulated=yes that blindly enables all emulated features
- making "-cpu ...,check" prints a warning for emulated features
unless emulated=yes
So:
-cpu foo,+emulatedFeature just works
-cpu foo,+notEmulatedFeature still sets the CPUID bit for that feature
-cpu foo,check prints warnings for all cpuid bits not in the
"allowed" bitmap. It prints different warnings depending on whether the
bit is in "emulated" or not
