With the Intel microcode update that removed HLE and RTM, there will be different kinds of Haswell and Broadwell CPUs out there: some that still have the HLE and RTM features, and some that don't have the HLE and RTM features. On both cases people may be willing to use the pc-*-2.3 machine-types.
So instead of making the CPU model results confusing by making it depend on the machine-type, keep HLE and RTM on the existing Haswell and Broadwell CPU models, and introduce "Haswell-noTSX" and "Broadwell-noTSX" CPU models later, for people who have CPUs that don't have TSX feature available.
Eduardo Habkost (2): Revert "target-i386: Disable HLE and RTM on Haswell & Broadwell" target-i386: Haswell-noTSX and Broadwell-noTSX
No objections from a generic CPU point of view. Only thing that comes to mind is whether it might make sense to hierarchically make Broadwell the parent type of Broadwell-noTSX, to avoid duplication. But then again we already have a lot of it. ;) Regards, Andreas
