[Qemu-devel] [PATCH 0/2] target-i386: Haswell-noTSX and Broadwell-noTSX CPU models |

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.

Revert "target-i386: Disable HLE and RTM on Haswell & Broadwell"
