Subject: [Qemu-devel] [PATCH v3 2/6] target-i386: Rename KVM auto-feature-enable compat function
Date: Fri, 3 Oct 2014 16:39:47 -0300 [thread overview]
Message-ID: <1412365191-22858-3-git-send-email-ehabkost@redhat.com> (raw)
In-Reply-To: <1412365191-22858-1-git-send-email-ehabkost@redhat.com>
The x86_cpu_compat_disable_kvm_features() name was a bit confusing, as
it won't forcibly disable the feature for all CPU models (i.e. add it to
kvm_default_unset_features), but it will instead turn off the KVM
auto-enabling of the feature (i.e. remove it from kvm_default_features),
meaning the feature may still be enabled by default in some CPU models).
