Subject: [Qemu-devel] [PULL v2 1/5] target-i386: Rename KVM auto-feature-enable compat function
Date: Tue, 4 Nov 2014 17:30:43 +0100 [thread overview]
Message-ID: <1415118647-16359-2-git-send-email-afaerber@suse.de> (raw)
In-Reply-To: <1415118647-16359-1-git-send-email-afaerber@suse.de>
From: Eduardo Habkost <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).
