From 711956722c6764336f8b78a2106e57c55f02f36d Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Tue, 3 Nov 2015 17:24:18 -0200 Subject: target-i386: Remove ABM from qemu64 CPU model ABM is not available on Sandy Bridge and older, and we want to make the default CPU runnable in most hosts, so it won't be enabled by default in KVM mode. We should eventually have all features supported by TCG enabled by default in TCG mode, but as we don't have a good mechanism today to ensure we have different defaults in KVM and TCG mode, disable ABM in the qemu64 CPU model entirely.
